Water quality testing resistance meter RM-220

Chinese film MINIPORE brand water testing resistance meter RM-220 This compact pocket detection table can measure the surface impedance, but also measure ground resistance, wide measuring range from 103 ohms / □ to 1012 ohms / □, accuracy is ± 1 / 2 range. Using ASTM Standard D-257 parallel electrodes sensing method, you can easily and repeatedly measuring a variety of conduction, electrostatic discharge type, insulation type surface. Technical Specifications Product introduction This compact mini detection table can measure the surface impedance, and can measure ground resistance, wide measuring range from 103 ohms / □ to 1012 ohms / □, accuracy of ± 1/2 range. AE-700 using ASTM D-257 standard parallel electrode sensing method, you can easily and repeatedly measuring a variety of conduction, electrostatic discharge type, insulation type surface. Product Function Description To measure the surface impedance, measured on the surface of the table, hold down the red measurement (TEST) button for bright light-emitting diode (LED) for the indication of the measurement of surface impedance magnitude. 103 = 1 Kohm green LED 104 = 10 kilohms green LED 105 = 100 kilohms green LED 106 = 1 megohm yellow LED 107 = 10 megohms yellow LED 108 = 100 megohms yellow LED 109 = 1000 megohms yellow LED 1010 = 10000 megohm yellow LED 1011 = 100000 megohms yellow LED 1012 = 1000000 megohm red LED> 1012 = red LED measuring insulation resistance to ground into a grounded grounding wire (Ground) socket, so that the right side of the detection electrode insulation sheets ( and outlet on the same side). The alligator clip connected to your ground. The table on the test surface, hold down the measurement (TEST) button for glowing LED indicates the magnitude of the resistance on the ground. This measurement value in ohms. Power supply 9-volt alkaline battery PP3 9 V rated voltage measured relative humidity 0% to 90% (non-condensing) Accuracy ± 10% Repeat accuracy ± 5% by weight of 170 grams (60Z) Size 127 × 76 × 26 calibration cycle: every ten months for an AE-700 surface impedance calibration table. AE-700 surface impedance meter calibration method: using decimal resistance box, the standard measurement resistor across between two parallel electrodes AE-700 meter to test its display of impedance values ??are correct.
