Weschler Elapsed Time Meters


Weschler GH-332, GH-352 & BH-351 elapsed time meters indicate the total time that a particular circuit is energized. They are used for maintenance scheduling of electrical equipment (including diesel generators, motors, welders, and radio and television transmitters) and tube replacement programs. Each consists of synchronous motor and cyclometer type register. When energized by the circuit being monitored, the motor drives the register (which has six digit wheels) to indicate up to 99,999.9 hours or minutes as a highly visible numerical strip across the center of the dial. The meters are housed in an attractive molded case with brushed aluminum front. They are available with or without reset knob.  Non-reset models are weather resistant.

Type GH352 and BH351 are 3½ inch meters.  Type GH332 house the same mechanism in a smaller 2½ inch footprint.
