ALLY - M01 micro-nano ammeter, can measure extremely small current, the highest resolution of 0.01 nA, nA measuring range 0 ~ 1 a, using the principle of I/V conversion, using ultra-high precision op-amp, put tiny current signal into a voltage signal can be measured, and measurement show that this instrument provides output voltage signal, which converts the current linear output voltage can be measured, cooperate with other instruments (oscilloscope, etc.), can be to higher-end micro current measurement,
Micro-nano ammeter can be used in the development of the Internet of low power consumption equipment debugging, sensor development and debug and so on need accurate measurement of tiny current field,
Micro-nano ammeter is extremely competitive, high precision, large range, but the price is only one over ten of similar performance instrument or even one percent,
A low cost and high precision, an ammeter
