The Triplett MM870 is an industrial-grade digital multimeter (DMM), made for professionals who require precision, dependability, and resilience in demanding settings. It covers both professional and DIY use by providing accurate measurements of AC/DC Voltage and Current, uA Current, Resistance, Temperature, Capacitance, Frequency (both electronic and electrical), and Duty Cycle. The device is equipped with True RMS for enhanced accuracy in non-sinusoidal or noisy waveforms and features a backlit 6000/60,000 count LCD display with a bargraph for easy reading. The MM870 comes with an LPF (low pass filter) to reduce frequency and harmonic interference, especially useful when assessing variable frequency drives. It has a Peak Hold (>1ms) with Min/Max that captures and displays peak values for comprehensive analysis. The device also logs Min/Max/Average values and has a Data Hold function to pause measurements, along with an AutoHold feature that refreshes readings when a new stable reading is detected. The Relative mode is handy for comparison measurements against a saved reference value. The meter is robustly constructed, waterproof (IP67), drop-resistant up to 6.5 feet (2 meters), and complies with a CAT IV 600V safety rating.
