MS121 Tester For Diagnostics Of Electromagnetic Valves And Clutches Of Vehicle AC Compressors

Product Description

MS121 Tester for diagnostics of electromagnetic valves and clutches of vehicle AC compressors

Tester MS121 is a compact device for testing both electromagnetic clutches and control valves of automotive climate systems.

Purpose:

Tester MS121 is used to perform quick and easy check of the following parameters of electromagnetic clutch and control valve:

• presence of a diode
• current consumption
• short circuit (cs)
• circuit break (cb)
• rate of valve opening

Both clutch and valve can be tested either on the compressor removed from a car (at a repair shop) or directly on a car.

Advantages:

• Simplicity and ease-of-use;
• Automatic polarity selection for connection of the tested unit;
• Simultaneous testing of a clutch and a valve;
• Possibility of a compressor electromagnetic valve control;
• Possibility to test without removing from a car.
