1. When the temperature measurement in the furnace is successful, the temperature value will be maintained automatically.
2. Lights and buzzers simultaneously prompt the end of temperature measurement (the test gun can be lifted).
3. Alarm for coupling breaking, over range, power under voltage, etc
4. The power supply adopts Ni MH rechargeable battery (it can measure temperature thousands of times after one charge). Turn on the power, when there is no signal input for 2 minutes, automatically turn off the power (power saving)
5. Five kinds of thermocouples can be used. Because of the anti-interference measures adopted, it has excellent anti-interference ability. When the medium frequency furnace is electrified for melting, it can measure temperature in the furnace without power off.
