SANWA · Analog Multitesters
SP21
Shockproof taut-band tester with continuity beeper.
- Taut-band
- Continuity beeper
- ±DCV zero-center
The SANWA SP21 is a shockproof analog multitester for users needing voltage, current and resistance measurement with an audible continuity check. It protects its circuit with both a fuse and a diode and offers a 500 µF capacitance check. Bhumika quotes this model for Canada.

Features
- Shockproof taut-band meter
- Zero-center meter for ±DC voltage
- Fuse and diode double protection against overvoltage
- Continuity beeper
- Battery check
- Tilt stand for easier reading
