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 a 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 a brushed aluminum front. They are available with or without a reset knob.  Non-reset models are weather resistant.

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