This item may be available in a different size, colour, scent, version or platform. Click below to be directed to product options:
It is tiny and small; dual display of current and voltage in the same time
It adopts excellent SMT technology and hence has good consistency
With voltage and current potentiometer for adjustment in avoid of error
It has a speacially designed hole for leading wire; dont need to cut/damage/change its original circuit for current measurement
Don't need to worry about "common ground" of current meter and you can test current in postive pole/negative pole of power supply or current of certain wire/equipment casually because its current sensor is totally separated from eletric of tested leading wire

Most Helpful Customer Reviews
I'm very pleased with this meter, it works well and easy to use. I'm a ham radio guy and I needed a meter that I could put on the positive side of the of power supply to my radio. Problem solved ! I will buy one again if need another.
I was prepared to calibrate but it worked well right out of the the package. I have a 100amp cable and I needed to strip the insulation from my cable to get it to fit through the hole on the coil.
works great and extended the coil wires 10 feet with an added shield of aluminium tape also purchased the 100 and 50 amp models
