Temperature Measurement Model C and Model D has Temperature Measurement function available. NCV Function Non-contact high voltage detection, the higher the voltage,3 different warning, the higher the voltage, the number will show from 1 to 3. 3 means the voltage is very high and very close. LED Flashlight &Backlit Screen We adopted LED Flashlight &Backlit Screen design which is Convenient for dark working enviroment. Widely Application Highly appplied in home appliances maintenance, factory equipment maintenance, cellphone maitenance, computer maintenance ect. All the models will come with probes, the model with temperature test function will come with a temperature probes as well.
