Surface Resistance Testers Compared: 3 Listings
As an Amazon Associate we earn from qualifying purchases.
A surface resistance tester is a handheld meter that reads how resistive a coating, film or fabric surface is, which matters for static-control work. This page compares three listings whose titles name a surface resistance or surface resistivity meter. For each one it sets out the stated resistance range, operating temperature, battery arrangement and any standard the listing cites, and it marks what the listing leaves out.
Keep each figure with the listing it came from. The three listings use different units and different limits, so a number from one does not describe another. Listing data was checked on 2026-10-20.
Quick answer
If you need a surface resistance tester with a stated resistance range and a battery included in the box, the first listing covers both points: it states a range of 10^3 to 10^12 ohms and a 9V battery that is included. The second listing states a narrower range of 10³ to 10¹⁰ Ω and says its 9V battery is not included. The third listing mentions a 9V battery in its bullets but does not say whether one ships with it, and its listing text does not state a resistance range at all.
Before ordering any of the three, confirm the temperature band and the standard your work follows, because each listing states these in different units and with different wording.
Comparison table
| Listing | Stated resistance range | Stated operating temperature | 9V battery | Standard named |
|---|---|---|---|---|
| CINARIS HZR-100 surface resistivity meter (first listing) | 10^3 to 10^12 ohms, ±10% accuracy (bullets) | 5 °C to 49 °C, 5% to 90% RH (bullets) | Included (bullets) | ASTM D257 (specification field and bullets) |
| Surface resistance meter GM3110, plplaaoo brand (second listing) | 10³ to 10¹⁰ Ω, ±10% accuracy (bullets) | 0 to 50 °C (bullets); upper rating 50 °C (specification field) | Not included (bullets) | None named in the listing text |
| Portable handheld surface resistance tester, plplaaoo brand (third listing) | Not stated | 40 °F to 120 °F (specification field and bullets) | Battery type stated; inclusion not stated | ANSI (specification field); ANSI ESD S20.20, IEC61340-5-1 and ASTM D257 (bullets) |
The first listing: CINARIS HZR-100 surface resistivity meter
The listing names CINARIS and model HZR-100 and describes a handheld surface resistivity meter with a test lead, automatic range and LED indicator. Its specification fields list battery power, a measurement type of ohmmeter, a minimum and maximum operating voltage of 9 volts, and an item weight of 6.9 ounces. The stated dimensions are 5 x 2.8 x 1 inches, and the included components field reads “tester”.
The bullets give the resistance span as 10^3 to 10^12 ohms with ±10% accuracy. They say the LED indicators signal conductor, ESD anti-static compliance and fully insulated readings. They also state that a single 9V battery, which the bullets say is included, supports more than 40 hours of continuous use. The stated operating band is 5 °C to 49 °C and 5% to 90% RH, and the bullets refer to a self-calibration feature and ASTM D257 compliance.
- Stated range: 10^3 to 10^12 ohms, ±10% (bullets)
- Battery: 9V, included (bullets)
- Operating band: 5 °C to 49 °C, 5% to 90% RH (bullets; the specification fields show a lower rating of 5 °C and an upper rating of 49 °C)
- Standard: ASTM D257 (specification field and bullets)
This is the only one of the three that states both an included battery and a resistance range. It suits a buyer who needs the widest stated range here and a battery in the box on arrival. The listing does not give an electrode spacing, so check the lead and probe geometry on the product page before using it on a specific surface.
The second listing: GM3110 surface resistance meter
The listing title names the GM3110 as a handheld resistance tester with a high-definition LCD backlight, sold for ESD, electronics lab and industrial safety work. The specification fields list battery power with a minimum operating voltage of 9 volts, an upper temperature rating of 50 °C, an item weight of 6.5 ounces and a unit count of one. The brand field reads plplaaoo.
The bullets state a range from 10³ to 10¹⁰ Ω with ±10% accuracy, three resistance display modes and a 1-second response. They say the unit supports °C and °F readouts across 0 to 50 °C, has a backlit LCD and a data hold function, and has textured sides for grip. They also say the 9V battery is not included and that the package holds a ground wire and a manual.
- Stated range: 10³ to 10¹⁰ Ω, ±10% (bullets)
- Operating band: 0 to 50 °C (bullets); upper rating 50 °C (specification field)
- Battery: 9V, not included (bullets)
- Included: ground wire and manual (bullets)
Its upper stated range is 10^10 ohms, against 10^12 ohms for the first listing. The listing names no standard by name, so anyone who needs a named ESD or ASTM method should confirm the standard on the product page before buying.
The third listing: portable handheld surface resistance tester
The third listing’s title describes a portable handheld surface resistance tester with automatic range and LED display, and it names a humidity measurement range of 5%-90% RH. Its specification fields list battery power, a minimum operating voltage of 9 volts, a measurement type of ohmmeter, a lower temperature rating of 40 °F and an upper rating of 120 °F. The brand field reads plplaaoo and the item weight is 6.7 ounces.
Its bullets say the unit is certified to ANSI ESD S20.20, IEC61340-5-1 and ASTM standards. They describe one-key operation and a 9V battery that supports more than 40 hours of use. They say the method is based on the ASTM D257 parallel grid induction approach with automatic calibration, and they state operation from 40°F to 120°F with humidity up to 90% RH, noting that accuracy may vary above 65% RH. The bullets give no resistance range and no accuracy percentage.
- Standards: ANSI (specification field); ANSI ESD S20.20, IEC61340-5-1 and ASTM D257 (bullets)
- Operating band: 40 °F to 120 °F, up to 90% RH (bullets); accuracy may vary above 65% RH (bullets)
- Battery: 9V, inclusion not stated
This listing names more standards than the other two, but it gives the fewest numbers for the measured quantity. Choose it when the standard list matters more to you than a stated range, and confirm the range on the product page.
How these three were chosen
Each listing above has a title that names a surface resistance or surface resistivity meter. Other products that came up in related searches, including multimeters, a mold test kit and an insulation tester, are left out because they are different product types. Each listing’s figures come from its own specification fields and bullet points, and its check date is 2026-10-20.
Worked example: resistance range and temperature span
Start with the resistance ceiling. The first listing states 10^12 ohms as its upper limit, and the second states 10^10 ohms. The first ceiling is 100 times the second. Both listings start at 10^3 ohms, so the first spans nine decades and the second spans seven. That comparison reads only what the two listings state; it says nothing about how either meter behaves at the ends of its range.
Next compare the temperature bands. The first listing states 5 °C to 49 °C, a span of 44 °C. The second states 0 °C to 50 °C, a span of 50 °C. The third states 40 °F to 120 °F. Converted from those Fahrenheit values, that is about 4.4 °C to 48.9 °C, a span of about 44.4 °C. The converted figures are arithmetic on the listing values, not numbers the third listing gives in Celsius.
The bands are close in width, so the decision turns on where each one starts and stops. If your work stays between 5 °C and 48 °C, all three stated bands cover it. Above 49 °C, only the second listing’s stated band includes the reading.
What the listings do not say
- None of the three states a test voltage applied to the surface. The first and third listings give 9 volts as an operating voltage in their specification fields, and the listings do not explain how that figure relates to a surface measurement.
- None states electrode or probe dimensions, which are part of how a surface resistance reading is set up.
- The third listing gives no resistance range in its text, so its measurement span cannot be compared with the other two.
- The second listing names no standard. The third lists ANSI in one field and three standards in its bullets, and the two sets do not match exactly.

Bottom line
For a surface resistance tester with a stated range and an included battery, the first listing matches both points on what it states. The second gives a stated range and a clear battery note, but its battery is not included and it names no standard. The third names the most standards but states no resistance range. Match the listing to the requirement your work cannot do without, and confirm the rest on the product page.
