Automatic Wheel-Track Tester GD-0719A

Features :

1. PWM temperature control. It can control: (1) Water temperature in chamber during water immersed wheel track test
(2)Ambient temperature of constant temperature chamber at a time.
2. The constant temperature chamber adopts outside circulatory heating mode. The uniformity and stability is good. No overshoots.
3. It shows time- displacement curves and time- temperature curves during a test.
4. It equips an absolute temperature sensor. No temperature drift in a long time test.
5. The mechanical structure adopts wheel movement mode.
6. One wheel tester. It can determine both water immersion test or no water immersion test.
