100 Digital Multimeter

No more guessing what range to switch your meter to: the TPI 100 does it automatically!

  • Automatically switches between ACV, DCV, and ohms (resistance). Benefit: Simple to use. Meter selects function and range, just connect the leads to the device under test.
  • Single button operation. Benefit: Easy to use. Enables users with limited knowledge to perform tests safely.
  • 0 to 600 volts AC and DC. Benefit: Enough range to safely perform measurements.
  • 10 MΩ internal impedance. Benefit: High impedance prevents inaccurate reading caused by circuit loading.
  • Auto power off. Benefit: Increases battery life by turning off the multimeter when not in use.
  • 4,000 count display
  • Up to 40MΩ
  • cULus 61010-1
  • CAT II – 1000V, CAT III – 600V

Frequently Asked Questions

1. Is there a way to measure higher current with a TPI DMM?

TPI DMMs (except the 120 and 126) have the capacity to read up to 10A AC/DC. Optional adapters are available for all models to increase the current range. Our shunt adapters are available to increase the range up to 1,000A AC/DC.

2. What other adapters are available for TPI DMMs?

Various adapters including carbon monoxide (A771), pressure (A620/630), and clamp-on low current (A254) are available. Contact TPI for additional information.

3. Which of the TPI DMMs will measure temperature?

All TPI DMMs can measure temperature by using the optional A301 K-Type thermocouple temperature adapter.

4. Which TPI DMMs can measure DC millivolts?

All TPI DMMs measure millivolts. Models are available with 1 or 0.1 millivolt resolution.

5. Which TPI DMMs can measure DC microamps?

The TPI 126, 133, 135, 153, 163, 183, 190, 194, 196, and 440 all have this capability.

6. Which TPI DMMs will measure capacitance?

The TPI 135, 183, 190, 192, 194, and 440 all have this capability.

7. What is continuity?

Continuity refers to a test performed on wires and circuits to see if a break(open) exhists. If the wire or circuit is continuous, the resistance reading will be at or near zero. The continuity range on a meter provides audible indication of a continuous circuit, allowing quicker tests without having to take your eyes off the circuit or wire under test.
