This Surface Resistance Meter can measure the resistance value on object surface by putting 2 parallel electrodes close to object surface to be measured, so as to judge whether the measured object is a conductor, static material or insulator. Meanwhile the meter can be used to measure the resistance to the ground of object, which is specially applied to different anti-static fields. Besides, it can measure the environment temperature for your reference.Features:Large LCD display for surface resistance test with switchable backlight for clear reading.3 ways to simultaneously display the surface resistance or material properties.Can measure environment temperature: 050 / 32122.Data hold, low battery indication, auto power off without operation in 30 seconds.Compact and portable size, light weight, easy to carry and operate.Switchable temperature units: Celsius() and Fahrenheit().Widely used in the fields of microelectronics, medicine, aerospace, professional machinery, etc.Specifications:Material: ABSResistance Measuring Range: 0.1x10^(3)1.5x10^(12)Conductor Material: 10^(6)Anti-static Material: 10^(6)10^(11)Insulator Material: ≥10^(12)Resistance Measurement Accuracy: ±10%Resistance Measurement Response Time: 1sTemperature Measuring Range: 050 / 32122Temperature Measurement Accuracy: ±2 / ±3.6Power Supply: 1 * 9V 6F22 Battery (NOT Included)Operating Environment: 050, 10~70RH%Item Size: Approx. 64 * 35 * 126mm / 2.5 * 1.4 * 5.0inItem Weight: Approx. 122g / 4.3ozPackage Size: Approx. 17.5 * 12.5 * 5.5cm / 6.9 * 4.9 * 2.2inPackage Weight: Approx. 241g / 8.5ozPackage List:1 * Surface Resistance Meter1 * Ground Lead1 * User Manual(English)
