Portable Surface Resistance Meter WT311 Handheld LED Display Resistance Test High Accuracy Backlight Resistance Measuring Tools: The surface resistance can be measured by attaching two parallel electrodes of the instrument to the surface of the measured object. Thus you can determine whether the measured object is a conductor, anti-static material, or an insulator. The instrument is particularly suitable for a variety of anti-static areas. Specifications: Resistance measurement range: 0.1x10³ - 1.5x10 Ω Resistance measurement accuracy: ±10% Resistance measurement response time: 1s Temperature Measurement Range: 0℃ -50℃ / 32-122℉ Temperature measurement accuracy: ±2℃/±3.6℉ Dimension: 63.6x31x125.8cm Weight:122g Scope Of Application: This product is a surface resistance tester which is an instrument for testing the surface resistance of objects. It is widely used in microelectronics, medicine, aerospace, precision machinery and other fields. Power Supply:1 x 9V 6F22 battery (Not included batteries) Color:Black & Red Material:plastic Package Contents: 1set * WT311 surface resistance tester
