Description

Martindale MM94 TRMS Digital Multimeter

The Martindale MM94 True RMS Digital Multimeter measures a wide range of electrical parameters plus temperature measurement, continuity testing and diode testing.

It measures DC voltage up to 1000V with a maximum resolution of 0.01mV whereas AC voltage is measured between 0 and 750V with 0.01mV maximum resolution. The multimeter is also capable of True RMS AC+DC voltage measurement.

For AC/DC current, there is a 0 to 20A measurement range with max resolution of 0.01µA whilst resistance can be measured up to 60MΩ. Conductance (60nS), capacitance (6mF), and frequency (10MHz) round out the Martindale MM94’s electrical measurement capabilities and it also able to perform duty cycle measurement. Temperature can be measured via a type-K thermocouple making the meter suitable for a wider range of applications. All parameters benefit from multiple ranges and resolutions in addition to a high degree of accuracy.

The measurement functions are selected using a clearly-labelled dial and the Martindale MM94 has min/max and peak measurement functions plus a high frequency filter and true RMS measurement. The 60,000 count backlit display shows all readings and features an analogue bar graph to show fluctuations dynamically.

The Martindale MM94 is safety rated as Cat IV 600V and Cat III 1000V and it has a battery life of roughly 50 hours. Test leads, a type-K thermocouple and batteries are included with the multimeter on delivery.
