"Our job is helping you do your job"
The Megger range of insulation testers are known worldwide for their rugged dependability, long service life, and accurate, reliable measurements. The Advanced models are an ideal choice if you need to record test results, transfer results to software/mobile app (via USB or Bluetooth LE), and want the benefits of more diagnostic insulation testing. The Advanced range also adds additional noise immunity for power distribution environments, and the ability to either increase or decrease the output current.

The Advanced range also adds additional noise immunity for power distribution environments, and the ability to either increase or decrease the output current.
Instrument productivity and accuracy are the focus of the MIT Series. An intuitive user interface ensures no lost time remembering how to use the tester. Simplicity of operation is achieved with two rotary switches and a large backlight display, which enables multiple measurement information to be displayed simultaneously. A graphical quick start guide is provided inside the lid of each model to assist first-time users and has QR code links to the online User Guide. The Advanced models provide an excellent ±5% accuracy up to 1 TΩ at 5000 V, 2 TΩ at 10,000 V, or 3 TΩ at 15,000 V.
One common feature across the whole range is the Megger "no compromise" approach to safety. The Megger level of safety will always go further than simply complying with the relevant safety standards. All Advanced models are safety rated to CAT IV 600 V up to 9842' (3000 m) altitude. The whole range features a dual case design with a tough outer case to protect the tester from knocks and drops, and a fire-retardant inner case. The case IP rating prevents moisture and dust ingress when storing or carrying the instrument. Case lids are removable for improved access to the terminals. A multitude of voltage warnings also help to ensure user safety.
Another common feature is the intuitive colour custom display, with its ability to work in extreme environments and unbeatable viewing angle. Advanced models also include memory storage with time/date stamping of results, logging of data, and recall of results to the screen. A fully isolated USB interface or on-board Bluetooth® interface is used for safe transfer of data to software. With the CertSuite Asset app, you can transfer results while testing, straight onto an Android or iOS mobile device or Windows laptop via USB cable or Bluetooth®.
