MS121
Tester for electromagnetic valves of AC compressors

Tester MS121 is a compact device for testing both electromagnetic clutches and control valves of automotive climate systems.
Manufacturer: MSG Equipment
Overview

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.

Features:

  • 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.
