TL;DR True-RMS with community-level corroboration on the EEVBlog forum · stronger evidence than a manufacturer-only claim, but not an accredited-lab bench test. The CAT III 1000V / CAT IV 600V rating is CE self-declared; no UL, CSA, or TUV certification is on file. Broad feature set (NCV, K-type temperature, capacitance, frequency) and very strong community reception make it a capable choice for basic-to-intermediate automotive work; if you need certified input protection for household AC or breaker-panel work, a UL-listed alternative is the more appropriate pick.
The HT118A is a 6000-count auto-ranging multimeter with True-RMS detection covering AC and DC voltage (up to 750/1000V), AC and DC current (10A max), resistance, continuity, diode, capacitance, frequency, duty cycle, K-type thermocouple temperature, and non-contact voltage detection · a broader function set than typical at this price point. The display is a large backlit LCD with a rear-mounted flashlight for dim spaces. Manufacturer-stated basic DC accuracy is ±0.5%, and community bench discussion on the EEVBlog forum generally finds the HT118A reads within its stated tolerance · a relatively rare outcome for a budget-tier meter. Input protection uses dual ceramic fuses with a PTC thermistor; interrupting capacity is not documented.
A home mechanic checking battery voltage, fuses, sensor signals, and 12V automotive loads will find the HT118A capable and accurate for those tasks, and the K-type temperature probe plus NCV alarm add real diagnostic usefulness. Skip it if you routinely probe household AC circuits, breaker panels, or service-entrance wiring · the absence of independent US laboratory certification means the CAT III 1000V / CAT IV 600V protection has not been tested by an accredited body at household or distribution-level fault energy, and a UL-listed Klein or Fluke is the more appropriate choice for that work.
The HT118A carries CE (EU self-declaration) and RoHS marks only · no UL Listing, CSA Certification, or TUV Certificate has been found for this model as of May 2026. No active CPSC recall is on file for KAIWEETS multimeters. Input protection is dual ceramic fuses plus a PTC thermistor per the manufacturer; specific fuse part numbers and kA interrupting capacity are not documented by KAIWEETS, and no authoritative HT118A teardown URL has been captured for community verification of the protection components. The meter runs on a standard 9V alkaline battery; dispose via a Call2Recycle drop-off location or participating retailer. At end of life the unit is standard e-waste · Best Buy and municipal e-waste collection accept handheld meters.
True-RMS is claimed by KAIWEETS in the listing title and feature bullets. Community discussion on the EEVBlog forum has generally corroborated functional True-RMS behavior on non-sinusoidal waveforms for the HT118A · relatively rare in the budget tier, where the True-RMS claim usually rests on the manufacturer label alone. This is stronger evidence than a manufacturer-only claim but not the same as an accredited-laboratory bench test.
No independent US laboratory certification has been verified for the HT118A. The meter carries a CE mark (EU self-declaration) and RoHS · both are self-declared conformity claims, not certifications by an accredited independent body such as UL, CSA, or TUV. Searches of UL Product iQ, the CSA Group database, and TUV databases as of May 2026 returned no listing for this model. The CAT III 1000V / CAT IV 600V rating printed on the meter body has not been independently tested to IEC 61010-1 energy levels by an accredited laboratory.
CAT (Installation Category) ratings define the fault energy a meter is designed to withstand during a measurement event. CAT III covers distribution-level circuits (breaker panels, commercial wiring); CAT IV covers the service-entrance level (utility connection, outdoor lines). CAT IV 600V on a budget meter is an aggressive label and is not common at this price tier. KAIWEETS states the rating is IEC rated, but the certification is CE self-declared with no UL, CSA, or TUV verification on file. The rating may well be functionally adequate · community discussion on the HT118A is generally positive · but it has not been independently tested by an accredited laboratory.
The HT118A ships with the multimeter, a set of silicone test leads, a K-type thermocouple temperature probe, a 9V alkaline battery (installed), and a user manual. Temperature measurement is available out of the box without additional accessories.
Yes. Non-contact voltage testing is listed in the feature bullets with a sound and light alarm when a live conductor is detected · useful for identifying live wires before probing. NCV is a notable feature differentiator versus comparably priced budget meters that omit it.
