Double Voltmeter

Designed to measure AC/DC current and Volt, these meters indicate true r.m.s. values and are substantially independent of system waveform.

Case Non-combustile ABS plastic material is used for making SF series'external case,and PPO plastic material is used for SF series's base; while Non-combustible PC plastic material is used for making SFT series'external case and base. Both of which will not suffer deformity under long-term use at 70°C and 120°C respectively.
Mounting SF series is flush mounting with bracket.
