1. Used to measure the electrical resistivity and ground resistance (RTG) of all conductive, anti-static, and electrostatic dissipative materials 2. Easy to use and high reliability. 3. Three-color flashing light indication: The flashing light is divided into green, yellow, and red components 4. One-click measurement: Place the meter on the surface of the object to be measured and hold down the "TEST" button. The continuously lit LED indicates the magnitude of the surface impedance of the measured object 5. Use scenario: mainly used to detect the surface resistance and grounding resistance of plastic, PE film, epoxy floor paint, cotton fabric, PCB material, acrylic material, PVC heat shrinkable film, plastic film, carton paper, foam and other items<br><br>Specifications: Measurement voltage: 9V Temperature range: Operating temperature: 5 ℃ -49 ℃, storage temperature: -15 ℃ -+60 ℃ Relative humidity: 0% to 90% (non condensation state) Resolution: ±10 Conversion point: 10 (3.16x10n) Conversion point accuracy: ±1/2 level Accuracy: ±15-20% Repeatability: ±5% Material: abs colour: Black<br><br>Package Contents: 1 x Electrostatic impedance meter 1 x Alligator clips<br><br>Only the above package content, other products are not included.
