Details
BEHATEST Earth Resistance Tester
Model: 91120
Introduction:
• The 91120 is a "professional instrument".
• The instrument is suitable for the testing of single earth electrodes such as lightning conductors and other small earthing system.
• The resistance of conductors such as continuity and conduit coupling joints can also be measured.
• Two-terminal operation measurement, which reduces the accuracy, can also be done by shorting P and C terminals.
• Earth resistance can be Measurement directly from 0.01 Ω up to 1999 Ω.
• The reading is displayed on a large, easy-to-read digital display.
• It has a zero 0 Ω adjustment setting that is controlled by a dial feature.
