ZH-6C Intelligent cold plate pain threshold detector is an instrument developed for screening acute pain and analgesic drugs, flick reflex test or plantar tenderness test. But these are the normal threshold of stimulus response in animals and belong to a kind of physiological pain. There are essential differences between physiological pain and pathological pain. Physiological pain is a set of alarm systems for self protection for survival, and pathological pain is a disease that prevents survival. Because of the difference between the two kinds of pain and the mechanism, the experimental methods of analgesic drugs are different. For example, some analgesic drugs have good analgesic effects on physiological and pathological pain. But some drugs only have effects on physiological pain, so different experimental methods and instrument can be used to screen different drugs with different action points. ZH-6C Intelligent cold plate pain threshold detector is an instrument that can perform physiological pain experiments and pathological pain experiments on the same instrument.

The instrument has the following basic requirements, except that the setting temperature is wide (-2℃~65℃), the temperature control accuracy is high (± 0.25℃), and the time error is small (error 0.01 second). It has the advantages of displaying the LCD screen in English, with its own micro printer, the USB microcomputer interface and the animal's full speed, the data display is complete, the observation of the animal is convenient, the time of lifting the foot and the times of lifting the feet are automatically accumulated.
