This Extech Non-Contact Phase Sequence Tester uses a non-contact voltage-testing method that permits easy connection to insulated conductors, avoiding uncertain and difficult connections to bare high voltage wires. Volts: 75 to 1,000 AC, Battery Included: Yes, Display Type: LED, Dimensions L x W x H (in.): 5 x 3 x 2, Frequency: 45 to 65Hz
- Simultaneous display of %RH, Temperature and Dew point or Wet Bulb or Probe Temperature
- Wet bulb measurements without slinging
- Calculates T1-T2 differential (Air Temperature-External Probe Temperature) using optional probe
- Unique sensor cap design twists to closed position for protection during storage
- Switchable °F/°C temperature units with 0.1° resolution
