Major Tech 1000A AC/DC TRMS Bluetooth Clamp Meter $365.00 + GST

The MT777 1000A AC/DC TRMS Bluetooth Clamp Meter has a CAT IV 600V rating and a 6000 count TFT colour display with an analogue bargraph that provides a fast sampling time with high accuracy. The meter has a built in Data logger with 100 Graph Data review, using Bluetooth, the meter wirelessly transmits data to the Android or iOS mobile App allowing the user to view, save, organise and share recordings. The VFD function allows the user to measure stable voltage in high frequency applications, while the Low Z range function has a low pass filter to eliminate errors caused by “Ghost” voltages. The meter measures 1000V AC/DC, temperature, frequency, capacitance and resistance measurements, plus 100ms Inrush current and Peak Hold. Using the optional MT740 True RMS Flexible Clamp Adaptor, the measuring range can be extended to measure 3000A AC.

This Bluetooth Clamp Meter has added features such as Non-Contact voltage detection, Data hold function and a built-in flashlight for dimly lit areas. Housed in a modern double moulded rubber housing.
