Programmable Temperature and Humidity Chamber

Introduction
· This device can be used to measure high temperature, low temperature, thermal-cold cycling, constant temperature and humidity, rapid temperature change, and alternate change between high and low temperature.
· Temperature rise and fall, humidification and dehumidification can be controlled separately. Hence, the efficiency of the device is improved to save over 20% electricity, lower the breakdown rate, prolong the service life span and decrease the test cost.
· The touch setting mode is controlled by microprocessor with 12 sets of P.I.D automatic calculation function, which controls the temperature and humidity more precisely.
· The deviation of temperature and humidity can be revised by programming.
· When breakdown occurs to the temperature probe, it can be automatically detected.
· Automatic water circulation or water supplement.
