TPI 133 Digital Multimeter

The TPI 133 Digital Multimeter is a basic multimeter from TPI that can measure DC voltage (1000V), AC voltage (750V), DC current (10A), AC current (10A) and resistance (20MΩ) in addition to testing continuity and diodes. The manual ranging function offers choice to increase precision and the meter also has good basic accuracy of ±0.5%. Extremely high resolution of µA and mV makes the instrument suitable for a wide range of HVAC applications.

The extremely clear screen on the TPI 133 has extremely large characters so it is very easy to read in poor light. The user operates the TPI 133 with a simple dial and a data hold button which freezes the current reading on screen.

Supplied accessories include a rubber-boot case with a tilt stand, test leads, fuses and batteries. The TPI 133 is covered by a three-year warranty and is safety rated as Cat III 600V whilst the user can rely on the enormous 500-hour battery life.
