Plumstead Electrical Wholesalers now stocks the latest meters from the Hellermann Tyton group. Chat to one of our sales consultants for more information or read on and watch the video below.


Mercury is a professional TRMS multimeter with a built-in infrared camera, capable of measuring AC/DC voltage up to 1000V, AC/DC current up to 10A as well as resistance, continuity test, diode test, frequency, capacitance and temperature with K-type probe.

Other major functions include AC+DC mode taking into account DC components overlapping AC signals and current measurement with standard and flexible transducer clamps (provided accessory F3000U).

A camera with 80x80pxl resolution is built inside to get simultaneous readings of thermal and electrical values for the item under test.

MERCURY is provided with Data Logger function capable of carrying out and saving recordings of every parameter as well as displaying the values’ diagram.  Snapshots can be saved into BMP format inside a micro SD card supplied as accessory and Bluetooth permits connection with mobile devices (tablet/smartphone) through HTMercury APP creating reports to share measuring results.

The instrument was designed in compliance with safety standards IEC/EN61010-1 with double insulation protection according to CAT IV 600V or CAT III 1000V. MERCURY is equipped with analogue bargraph LCD and each function can be selected by rotary switch. Additional functions include HOLD to keep displayed data, MAX/MIN, PEAK and Auto Power OFF to save the internal rechargeable battery.


FLASHMETER is a compact DMM capable of carrying out TRMS voltage measurements up to 600V as well as resistance measurements automatically under autorange, just connecting input terminals. It was designed in compliance with safety standards IEC/EN61010-1 with double insulation protection under CAT IV 600V. FLASHMETER is provided with a white light torch, a probe to detect AC voltage without contact and is water resistant according to IP67.


The HT9022 is a professional clamp meter with power/harmonic measurement as well as a Bluetooth connection to Android devices with HTANALYSIS.

The power clamp meter HT9022 has been designed for measuring AC, DC, AC+DC TRMS current up to 1000A / 1000V to obtain CAT IV 600V in compliance with standard IEC/EN61010-1.

It also measures and records Active, Reactive and Apparent Power, Energy, voltage/current harmonic analysis up to the 25th with THD% calculation in balanced single-phase and three-phase systems. It also allows testing phase sequence and concordance with the 1-terminal measuring method. It is also possible to detect and record the events linked to motor starting (INRUSH) currents. HT9022 allows recording each measured electric parameter over time, with the possibility of transferring data via Bluetooth to Android devices through the HTAnalysis App or onto PC through the TOPVIEW software. The clamp is provided with a wide graphic dotmatrix screen (128x128pxl) with backlight, in order to allow reading data even in poorly lit environments, and it is provided with an auto power off function to preserve its internal battery.


Hellermann Tyton revolutionizes the portable instrument market by introducing the new JUPITER, the Multifunction Multimeter for electrical installation safety testing. The first multimeter which incorporates the functions available only in standard electrical safety testers and professional High-end multimeters.
