Product information:

 

HT-J0412-2 Transistorize millivoltmeter is a high-precision metrical instrument mainly for measuring sine-wave voltage and DC voltage. It is special for all kinds of school to do the electrical experiment during the physical teaching. It is also adopted by factory and research and development institution as the professional metrical instrument.
Adopting the high speed integrated circuit as input impedance transformer and direct-coupled amplification circuit as the signal amplification processing,this instrument has a wide range of measurement, high measuring accuracy and high EFT.
