The Digital Insulation Resistance Tester has safe configuration and improved electro-circuit. It is one new item with more functions, higher precision, and easier operation. It' s also one quake-proof, dust-proof and damp-proof tester for outdoor use.

Features:
Capability: Can do the test at several test voltages: 100V, 250V, 500V, 1000V; voltage below AC750V can be tested; with resistance measurement ranging from 1 MΩ to 20 GΩ.
Practical Function: Auto switch the range when measuring resistance; data hold feature; low battery reminder and high voltage indicator.
Large LCD Display: Equipped with a 3 1/2 digits big LCD display with max value 1999, easy to read.
Safe to Use: Rugged housing is dust-proof and damp-proof; strong load capacity with output short-circuit current about 1.0mA; protective circuit prevents damage from voltage shock.
User-Friendly: Turn the rotary switch to select voltage; comes with test leads, alligator clips, and a kickstand on the back.
Wide Application: This tester can be applied in all kinds of electric equipment and insulation materials such as transformer, electromotor, cable, switch, appliance, etc.
