Simple description:
The UJ33A DC potential difference meter can measure DC voltage in laboratories, workshops, and on site, and can also measure DC resistance, current, power, and temperature after conversion. It can verify general voltage signals, such as thermocouple signals, which can also be converted through a conversion switch and output as voltage signals. It can be used to verify industrial instruments such as electronic potentiometers and millivoltmeters that measure voltage. The instrument is equipped with a transistor amplifier zeroing device and an unsaturated standard battery manufactured by our factory, which has a small temperature coefficient and good stability.
