Tegam Safety Voltmeter Model 100A
CAT III and CAT IV
The Model 110A Safety Voltmeter is the only single switch, single range, digital voltmeter that automatically measures AC & DC volts to 1000 V for voltage troubleshooting, line clearing, lock out/tag out procedures and anywhere hazardous voltages may be present. The 110A has a 1 MΩ current limiting resistor in each lead to protect the user against arc-flash potential.
Model 110A and meets CAT IV 600 V/CAT III 1000 V over-voltage protection under IEC-61010-1.
