Reliable Voltage and Continuity Testing

The TPT420 is engineered to handle a broad range of voltage situations, measuring from 12 to 1000 V AC and up to 1500 V DC. The continuity function spans 0 to 500 kO, with an acoustic sounder for added ease of use and safety. It operates below the tripping threshold in circuits protected by RCDs, RCBOs, and Safety Breakers, preventing unintentional disconnection during testing.

Built for Durability and Safety

Featuring a robust IP64-rated housing, the TPT420 is designed to withstand challenging environments. Its bright, integrated LED torch ensures you can work in poorly lit areas with ease. The device is safety rated at CAT IV 1000 V and conforms to the latest IEC/EN 61243-3 and DIN VDE 0682-401 standards. It includes GS38 probe tip shrouds as standard and comes with a protective storage and carry pouch.

Versatile Applications

The TPT420 isn’t just limited to electrical installations. Its versatile design allows use in automotive, fire alarm systems, and solar/PV systems. Whether you’re working in residential, commercial, or industrial settings, the TPT420 provides the reliability and accuracy you need.

AI Overview BETA

The Megger TPT420 is a voltage tester for measuring AC and DC voltage and checking electrical continuity. Voltage indication continues with depleted batteries, so a flat battery does not prevent voltage checks during electrical testing. Electricians and solar professionals can use its phase-rotation indication to identify phase sequence without crossing test probes across residential, commercial and industrial applications.

Measures 12–1000 V AC and 12–1500 V DC
Display combines 13 LEDs with a 4-digit LCD
Operates below the tripping threshold on RCD-, RCBO- and Safety Breaker-protected circuits
CAT IV 1000 V overvoltage category
IP64 protection against water and dust
