Best Fluke 28 Ii Rugged Digital Multimeter
Best Fluke 28 II Rugged Digital Multimeter: Three Rugged Fluke Meters Compared
As an Amazon Associate we earn from qualifying purchases.
The fluke 28 ii rugged digital multimeter is built for harsh industrial sites, where a standard hand-held meter may not survive a drop or a wet floor. The Fluke 28 II is IP 67 rated for water and dust, tested to survive a 3 m drop with its holster, and rated CAT IV 600 V and CAT III 1000 V. Its sibling, the 28 II EX, adds intrinsic safety for hazardous areas. The Fluke 87V is an older rugged industrial meter that many electricians still use. This guide compares the three and explains which one fits which job.
How we chose
We searched our product list for rugged Fluke multimeters. The Fluke 28 II and the 28 II EX matched by name. The Fluke 87V matched as the other rugged industrial meter in the same Fluke line, so we included it as a comparison pick. We did not add meters from other families, such as the 117 or the 15B+, because they are not built to the same industrial rating. Other Fluke items in the list are clamp meters, insulation testers or test leads, and they are outside this comparison.
For each pick we read a Fluke page or a retailer page in full. The Fluke product page gave us the specifications and safety ratings for the 28 II. The Fluke category page gave us the rating and voltage summary for the 87V and the 28 II EX. The Amazon listing for the 28 II EX gave us its certifications and temperature range. We left out prices, star ratings and warranty length, which are not part of this comparison.
Quick answer
- Fluke 28 II: the general rugged pick. IP 67, true RMS, 1000 V AC and DC, CAT IV 600 V and CAT III 1000 V, 3 m drop rating.
- Fluke 28 II EX: the intrinsically safe version for hazardous locations, with a -200 °C to +1090 °C temperature range in its listing.
- Fluke 87V: an older industrial meter that many plant electricians already use. The Fluke category page gives a rugged rating only for the 87V MAX variant, so we do not assign that rating to the plain 87V.
Fluke 28 II: the rugged industrial meter
The Fluke 28 II is the core of this guide. The Fluke product page describes it as completely sealed against dust and water with an IP 67 rating, and designed and tested to survive a 3 m drop with the holster. It is rated for an operating range of -15 °C to +55 °C, with a short-term tolerance of -40 °C for up to 20 minutes, and handles 95% humidity.
The meter measures true-RMS AC voltage and current, with min, max and average recording, peak min-max capture at 250 µs, a relative mode and a built-in thermometer. The listed voltage range is 0.1 mV to 1000 V for both AC and DC, and current is 0.1 µA to 10 A for DC and AC. Resistance goes from 0.1 Ω to 50 MΩ, capacitance from 1 nF to 9999 µF and frequency from 0.5 Hz to 199.99 kHz. The display has 6000 counts with a 20,000-count high-resolution mode.
On safety, the Fluke page lists CAT IV 600 V and CAT III 1000 V, compliance with second-edition IEC and ANSI electrical safety standards, and MSHA approval for mine work. Fluke states that the meter gives accurate readings on noisy equipment such as variable-speed drives, which is a common reason to choose a true-RMS meter on an industrial floor.
The page gives a size with holster of about 6.35 × 10.0 × 19.81 cm and a weight with holster of 698.5 g. It runs on three AA batteries, which the page rates at 800 hours. The meter also has a backlit keypad, a two-level backlight and a reversible holster, and an optional magnetic hanger is available.
Who the 28 II suits
Choose the 28 II if you work in plants, mines or outdoor sites where the meter may be dropped, splashed or used near variable-speed drives. It is the default rugged choice when intrinsic safety is not required.
Fluke 28 II EX: the intrinsically safe sibling
The Amazon listing for the Fluke 28IIEX/ETL carries the words intrinsically safe and ETL in its title, and gives a temperature range of -200 °C to +1090 °C. That makes it the version to consider for work in hazardous or classified areas, where an ordinary meter could create an ignition risk. The EX version shares the rugged build and the true-RMS measurement of the standard 28 II, so most of the feature set matches.
We did not confirm the CAT rating, voltage ratings or ATEX details for the EX version on a page we read in full, because the listing text was longer than our reader could return in one pass. Check the certification label and the manual for the exact ratings and approved hazardous-area zone before you buy.
Who the 28 II EX suits
Choose the 28 II EX for oil and gas, chemical, or other classified areas that require intrinsically safe test equipment. If your site does not require it, the standard 28 II is the better value.
Fluke 87V: the older industrial workhorse
The Fluke category page we read names the 87V in its list of meters. Its rugged description (IP 67 outer shell and a 1000 V AC and DC rating) appears for the 87V MAX variant, not for the plain 87V. The same page says the Fluke 28 II and 27 II are IP 67 rated and tested to withstand a 3 m drop. We did not open a full specification page for the plain 87V, so its figures are limited to the names and groupings on that category page.
The 87V is a useful comparison because many plant electricians already own one, and it covers the same basic measurements of voltage, current, resistance and frequency. We could not confirm the IP 67 sealing or the 3 m drop rating for the plain 87V on a page we read, so check the current listing before assuming it matches the 28 II.
Who the 87V suits
Choose the 87V if you need a familiar industrial meter and your team already uses the Fluke 87V model range. For the strongest rugged rating in this group, the 28 II is the stronger pick.
What we could not verify
- The Fluke 28 II specifications come from the Fluke product page we read. We did not confirm the same figures on a separate retailer page.
- The CAT rating of the 28 II EX and the ATEX approvals were not on a page we read in full.
- We did not open a full specification page for the plain Fluke 87V, so its figures in this guide are limited to the category listing.
- The IP 67 and 3 m drop claims are not confirmed for the plain 87V, so we do not state them for that model.
Tips before you buy
Match the meter to the environment before you match it to the budget. A rugged meter protects the reading only if the probes, leads and holster are in good condition, so inspect the test leads before each shift. For voltage work on high-energy circuits, confirm the CAT rating printed on the meter, and use the right probe category for the job. If you also test clamp current or insulation, our guide to how a current clamp works explains where a clamp meter fits next to a multimeter. For voltage presence checks, a non-contact voltage detector is a quick first step before you connect the meter.
FAQ

No. The EX version is marked as intrinsically safe and ETL-listed on its Amazon listing. It shares the rugged design and true-RMS measurement, but it is for classified hazardous areas.
Can the 28 II measure AC and DC voltage?
Yes. The Fluke page lists 0.1 mV to 1000 V for both AC and DC voltage.
How long does it run on batteries?
The Fluke page rates the 28 II at 800 hours on three AA batteries.
