Hammer type surface resistance gauge

TR7800 Type

A professional hammer surface resistance tester, also known as an impedance tester or megohmmeter, is used to measure the impedance or resistance of all conductive, antistatic, and electrostatic venting surfaces. Easy to use, high quality, and highly reliable, the meter can also measure relative humidity and temperature, which affect electrical properties.

Features:
• Power supply: 9-volt battery or adapter;
• Test voltage: 10V/100V;
• Resistance range: 103-1012 OHM;
• Accuracy: 10%;
• Accurate resistance tester.

Fields of application

The TR7800 Professional Hammer Surface Resistance Tester, also known as Impedance Tester or Megohmmeter, is used to measure the impedance or resistance of all conductive, antistatic, and electrostatic venting surfaces. Easy to use, high quality, and highly reliable, the meter can also measure relative humidity and temperature, which affect electrical properties.

Intuitive display of values, temperature, humidity

The ASNI/ESDA Association and the European CECC recognize the influence of environmental conditions at the time of measurement, so their standards require the recording of temperature and humidity, if a material is measured under high humidity conditions and all the measurement requirements are passed, but the customer receives the material and uses it at low temperatures and low humidity, it is possible that the material will not meet the requirements.
