Huazheng HZJQ-W1 Insulation oil dielectric strength tester with oil temperature testing function

The instrument is controlled by a high-capacity single-chip microcomputer, which is stable and reliable.
It is equipped with temperature, humidity, and clock display functions, and can be customized for infrared oil temperature measurement.
A wide-range watchdog circuit is integrated into the instrument to prevent crashes.
The instrument program includes GB/T 507-1986, GB/T 507-2002, DL 429.9, IEC 156, and self-programming operations, allowing for a variety of options to suit different users' needs.
The oil cup is made of special glass and high-polymer materials, processed to prevent oil leakage and corrosion.
The unique high-voltage sampling design allows the test value to enter the A/D converter directly, avoiding errors in the analog circuit and resulting in more accurate measurements.
The instrument features over-current, over-voltage, short-circuit, and other protection functions, with strong anti-interference ability and good electromagnetic compatibility.
It can switch between Chinese and English to meet the needs of any customer.
