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: ABS Resistance 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: 1s Temperature Measuring Range: 050 / 32122 Temperature Measurement Accuracy: ±2 / ±3.6 Power Supply: 1 * 9V 6F22 Battery (NOT Included) Operating Environment: 050, 10~70RH% Item Size: Approx. 64 * 35 * 126mm / 2.5 * 1.4 * 5.0in Item Weight: Approx. 122g / 4.3oz Package Size: Approx. 17.5 * 12.5 * 5.5cm / 6.9 * 4.9 * 2.2in Package Weight: Approx. 241g / 8.5oz Package List: 1 * Surface Resistance Meter 1 * Ground Lead 1 * User Manual(English)
