The Jaltest WST (Wear Sensor Tester) is a diagnostic tester for checking the operation and condition of wear sensors on brake pads of commercial vehicles. This portable device is equipped with a built-in, rechargeable battery and an LCD screen that directly displays measurement values such as voltage, wear percentage, and the K-factor. The tester is designed for workshop use to verify the sensor status without the need to disassemble the wheel.
The device supports both 2-wire and 3-wire sensors and is compatible with systems from leading manufacturers. In addition to reading sensor values, the WST also checks the electrical installation between the sensor and the ECU. A two-color LED indicator (green/red) provides a quick visual indication of the sensor status. Charging the internal battery is done via a USB connection.
