The MIT230 incorporates a range of safety and operation features in one of the smallest electrical insulation testers available. Its LCD offers a combination of digital readout and analogue display, with an analogue pointer response for evaluating circuit charge and discharge characteristics. The instrument housing is in tough ABS.

Insulation testing to 1000 MΩ
Dual & triple test voltages models
Digital display with electronic analogue arc display helps to confirm insulation condition & to monitor fluctuating readings not apparent on the digital display
Continuity testing at 200 mA down to 0.01 Ω resolution
Automatic discharge of circuit under test
1 mA test current at selected voltage range
Default voltmeter automatically switches in when the instrument is connected to a circuit with an AC or DC voltage greater than 25 V
Auto-ranging analogue arc scale shows only the scale in use
Live circuit warning above 25 V, also inhibits insulation & continuity tests above 50 V
Lead resistance compensation on continuity
Hands free continuity testing Auto power-down after 5 min

When measuring voltages, the use of fused test leads is recommended for personal safety.

6 x AA alkaline batteries, test leads, crocodile clips, carry case, instructions

Check that your system is running strong with this insulation tester from Megger. By testing resistance levels, it identifies current leaks to minimise the risk of electrical hazards. As it has settings for test voltages of 250, 500 and 1000V DC, it's a versatile piece of kit. Simple dial controls take the hassle out of switching between the tool's functions. As it automatically runs continuity tests on devices, it checks for many faults at once to help you fly through maintenance.

• Detects resistance levels between 10kΩ and 1000MΩ for versatility
• Best resistance measurement accuracy of ±3% for precise readings
• Dual digital and analogue readout for clear results
• Battery life of up to 3000 five-second tests for long-lasting performance

• Electrical engineering
• Power generators
• Construction sites

No, this device comes with test leads and crocodile clips, so you can start testing straight away. It also arrives with a storage case for convenient storage.
