Extech PRT200 Non-Contact Phase Sequence Tester. 75to 1000VAC (45-65Hz) The Extech PRT200 Checks phase sequence and phase status. It tests from 75 to 1000VAC (45-65Hz) with LED and audible indication. LEDs indicate phase orientation (clockwise or counter-clockwise) and whether each phase is live. A beeper sounds intermittently when correct phase is detected and continuously if phase is reversed. Durable housing with back cover magnet for attachment to an AC distribution panel for easy measurement. LED brightness is adjustable. Includes fully insulated alligator clips with wide jaws.

13 Function Wireless True RMS MultiMeter/Insulation Tester. MultiMeter/1000V Insulation Tester with Wireless PC interface (915MHz). Measure Insulation Resistance to 20GΩ 5 Test Voltage ranges Polarization Index (PI) and Dielectric Absorption Ratio measurements (DAR) Low Resistance measurement with Zero function Programmable Timer feature sets the duration of test Comparison Mode allows user to set the Pass/Fail values for insulation measurements Step Voltage (10% steps at 50% to 120% of range) Auto-discharge of voltage test signal Lock Power On Function for hands-free operation Manually ...

Phase Sequence and Motor Rotation Tester The Amprobe® PRM-6 Phase Sequence and Motor Rotation Tester can test the motor rotation of 3-phase systems and verify 3-phase receptacle wiring and phase sequencing with test leads. An additional advanced feature is wireless motor rotation detection, which senses motor rotation direction without use of test leads. This is particularly useful for fast-running motors when the motor rotation cannot be visually determined or when the drive shaft is not visible. Durably constructed with a rubber outer casing, the PRM6 has a bright, backlight LCD ...
