Electric kWh Meters for RV and Home: 3 Listings
As an Amazon Associate we earn from qualifying purchases.
This page compares three electric energy meters from the research set, with listing data checked on 2026-10-11. The keyword names an SC440 meter. None of the twelve listings in that research file is an SC440 model, so the page covers the meter product type that the set does contain: kWh meters sold for RV and home use, most of them stated for 240 volts. The three listings are the Meterly Centron CL200, the XaHo CL200 digital meter, and the JINDOUZI 240V digital meter.
These are energy monitoring listings, not voltage or current testers. Each listing states a voltage, a current test figure, and a standard in its own fields. Where two listings state different voltages for the same meter, both are shown, and the conflicts are part of the comparison.
Quick answer
The Meterly listing is the only one of the three whose main fields name the item as a certified CL200 meter for a 240v RV or home supply. The XaHo listing gives a TA30 figure of 30 test amps, and the JINDOUZI listing names the same TA30 capability without a number. The JINDOUZI listing also states a 240V title and a 120V standard working voltage in its bullets. That conflict is the most important point on the page. The Meterly listing is also the heaviest of the three by listed weight.
Check the supply voltage and the test current figure on the product page before comparing the listings further.

Meterly Centron SSEM CL200 KWH Meter
View the Meterly Centron SSEM CL200 on Amazon
The Meterly listing carries the title Centron SSEM CL200 KWH Meter, Type C1S, Form 2S, 240v RV or Home Meter, and it describes the unit as certified. The three bullets name an electronic LCD register, a polycarbonate cover, and a test LED, and the third bullet refers to unattended processing. The listing gives a weight of 2.53 pounds and a package size of 8.46 x 8.43 x 6.18 inches. It has no current test figure in the fields reviewed, and its specification table is the shortest of the three, with item weight, package size, and package quantity only. The listing does not state an installation requirement in the fields reviewed.
XaHo Digital Electric Meter for RV and Home
View the XaHo digital electric meter on Amazon
The XaHo listing carries a CL200 KWH watt meter title for RV pedestal and household use. Its bullets describe a precision LCD display, a TA30 current measurement with 30 test amps, and CL200 kWh monitoring. The listing states a 240V working voltage and says the meter meets ANSI C12.1 industry standards. It weighs 1.54 pounds and measures 7.09 x 5.51 x 7.09 inches. The color is white, and the included components field lists a box. The listing states its model number as Digital Electric Meter, which is a description and not a model code.
JINDOUZI Digital Electric Meter 240V
View the JINDOUZI 240V digital electric meter on Amazon
The JINDOUZI listing is titled 240V 2 Wire KWH Meter with a watt meter function, for RV and home use. Its specification table gives a 240V style and an AC power source, and it lists the model as TOZG6223. Its bullets state TA30 current measurement capability and CL200 kWh monitoring. One bullet describes a standard design with a 120V standard working voltage, which conflicts with the 240V figure in the title and style. The listing weighs 1.5 pounds and gives dimensions of 1 x 1 x 1 inches, which is an unusual size figure for a meter of this type and should be checked on the product page.
How we chose
The research file for this keyword held twelve listings. Three are kWh energy meters, and those three are compared here. The other nine are a tape measure, a Stetzerizer meter, a Klein clamp meter, a Fieldpiece clamp multimeter, an FNIRSI clamp meter, four multimeters, and none of them is an energy meter. The page does not use price or rating data. The SC440 label from the keyword does not appear in the listings, so the page is written for the product type the set contains.
Worked example: what a 30 test amp figure means at each stated voltage
The XaHo listing states a 240V working voltage and a TA30 figure of 30 test amps. Multiplying the two gives 7,200 watts. The JINDOUZI listing states a TA30 figure as well, but its bullet gives a 120V working voltage. The same 30 amp figure at 120V gives 3,600 watts. That is the arithmetic on the listed figures, not a rated power for either meter, and the listings do not state a power rating. The example shows why the voltage conflict matters: the same current figure yields two different numbers depending on which voltage the buyer relies on.
The Meterly listing states a 240v title but gives no current figure in the fields reviewed, so no equivalent calculation can be made for it.
What the listings do not say
None of the three listings states an accuracy class for energy measurement, a measurement range, or a test current beyond the TA30 figure on two listings. The Meterly listing states no current figure at all in the fields reviewed. The XaHo and JINDOUZI bullets use the same TA30 wording, but the listings do not explain what the 30 test amp figure means in use.
The listings do not state installation requirements, wiring instructions, or the approval status of the meter in any jurisdiction. Any meter connected to a supply should be installed as the product page and local rules require, and the supply voltage should be confirmed first.
FAQ
Is the SC440 one of these meters?
No. None of the twelve listings in the research file is an SC440 model. The three energy meters in this comparison are the closest product type in the set.
Which of these meters states a 240V working voltage?
The Meterly title gives 240v, the XaHo listing states a 240V working voltage, and the JINDOUZI title and style give 240V. The JINDOUZI bullets also state a 120V standard working voltage.
What does the TA30 figure state?
The XaHo listing describes TA30 as current measurement of 30 test amps. The JINDOUZI listing states TA30 current measurement capability without a number. The Meterly listing states no TA30 figure in the fields reviewed.
Do the listings state installation requirements?
No listing states installation requirements in the fields reviewed. Check the product page and local rules before connecting any meter.
Conclusion
The three energy meters in this set are close in purpose, and they differ mainly in how clearly they state their voltage and current figures. The XaHo listing is the most consistent of the three on voltage and TA30 figures. The JINDOUZI listing has a voltage conflict between its title and its bullets. The Meterly listing states a 240v title and certification, but it gives no current figure in the fields reviewed. None of the three should be chosen on the strength of the listing text alone without first confirming the supply voltage and the product page details.
