Weschler Instruments - Analog Instruments:
Application:
Weschler Types 351 and 371 meet all performance requirements of ANSI C39.1-1981 for round and rectangular panel instruments.

Ammeters (dc, ac, radio frequency)
Millivoltmeters (dc)
Voltmeters (dc, as, rectifier)
Frequency Meters (transducer type ac)
Wattmeters (transducer type ac)
Varmeters (transducer type ac)
Motor Load Indicators (ammeter, wattmeter, inphase current)
Power Factor Meter (transducer type ac)

Features:
High Torque to Weight Ratio: Insures rapid, accurate readings with high damping and minimum frictional effect.

Easy to Read Scales: Linear on dc. Virtually linear above 10% of full scale on ac.

Self Shielding: DC types are magnetically shielded and calibration is unaffected regardless of material or thickness of mounting panel. AC types incorporate an internal coil-shield.
