SP21

With continuity check beeper

Calibration available products

Employs shockproof taut-band meter that is not easily damaged even if dropped
Zero center meter for ± DCV measurement
Double protection with fuse and diode to protect the internal circuit from overvoltage
Battery check
With a tilt stand that helps to read the meter

Drop shock proof
The meter element is furnished with a taut band and impact-resistant design enough to withstand a shock of drop.
Capacitor
Capacitor capacity (electrostatic capacity) is measured and expressed in the unit of F (farad), μF, etc.
Continuity buzzer
The buzzer sounds when the measuring object is electrically conducting.
Battery check
Battery voltage is measured and assessed by running a given current.
Zero-center meter (NULL)
Moves the indicator of the analog tester to the center of the scale (meter graduations) to make measurement of positive and negative voltage.
