It can measure the resistance value on object surface by putting two 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 ground of object￡? which is specially applied to different anti-static fields. <br> <br> <strong>Features:</strong> <br> Can measure surface resistance value and resistance to ground. <br> Ambient temperature measuring. <br> High precision and with compensation function. <br> It's possible to measure surface resistance of conduction type￡? static tapping type and insulation type materials. <br> LCD back light for easier and clear reading. <br> <br> <strong>Specifications:</strong> <br> Measuring Range of Resistance: 10^(3) - 10^(12) Ohm <br> Repeated Accuracy: (+/-)5% <br> Measuring Range of Temperature: 0-50??C? <br> Repeated Accuracy: (+/-)2??C <br> Measuring Accuracy: (+/-)10% <br> Response Time of Resistance Measurement: 1s <br> Humidity: 0%-70% Non-Condensing <br> Operating Temperature: 0-40??C? <br> Storage Temperature: -10-70??C? <br> Power Supply: 9V 6F22 Battery (NOT included) <br> Product Size: 13 * 6 * 3cm / 5.12 * 2.36 * 1.18in <br> Product Weight: 112g / 3.95oz <br> Package Size: 21 * 13.5 * 4.5cm / 8.3 * 5.3 * 1.77in <br> Package Weight: 165g / 5.82oz <br> <br> <strong>Package List:</strong> <br> 1 * Surface Resistance Meter <br> 1 * Ground Lead <br> 1 * User Manual (English)
