Brymen BM135ma clamp meter
Details
The Brymen BM135ma is a premium clamp meter, suitable for all current work on automotive, appliance and electronics circuits. This clamp meter uses the patented AmpTip jaws to read currents down to 0.001A right at the jaw tip, so even thin conductors and sub-ampere loads are measured accurately, while the jaw centre handles up to 200A AC and DC. True-RMS sensing keeps readings correct on distorted waveforms, a direct LPF mode reads the fundamental voltage and frequency of variable frequency drives, and dual sensitivity EF detection traces live lines without contact. BeepLit continuity and diode tests add an audible and backlit alert, and the meter is rated to CAT III 600V and CAT IV 300V with 6kV transient protection.
