　　IIHigh and low temperature humidity test chambercontroller:

　　7-inch brand new true color LCD touch display

　　Controller specifications:

　　1. The parameter setting adopts human-computer dialogue mode, only requiring touch input of temperature and humidity; The automatic operation function of the test box can be achieved. It can store 120 program groups, and each program group can set 100 segments of programs. Each program can be set to run for 99 hours and 59 minutes, with 999 cycles that can be repeated infinitely

　　2. Screen display: 5.7-inch LCD, brand new true color LCD touch display

　　3. Setting accuracy: Temperature: 0 1 ℃ humidity: 1% RH

　　4. Display accuracy: Temperature: 0 01 ℃ humidity: 0.1% RH

　　5. Running mode: Fixed value running, program running

　　6. Communication function: equipped with standard RS232/RS485 communication interface, transmission distance of 1.2Km, communication speed of up to 9600bps per meter, can be connected to a computer for remote monitoring, easy to operate.

　　7. Auxiliary functions: Fault alarm and cause prompt function, fault name can be changed, temperature upper limit protection function, timing and reservation (automatic stop and automatic start function), multiple sets of PID separate segmented temperature control, curve display and saving function to display PV curves for 0-8 days. The temperature can be set to operate linearly (i.e. set the rate of rise/fall per hour)

　　IIITemperature and humidity cycling test boxHeating and humidification system:

　　1. Heater: Nickel chromium alloy wire type heater, automatically calculates high-precision PID+SSR control (calculation cycle: 1-4 seconds can be set), making its heat loss equivalent to the heating amount, thus saving about 30% electricity compared to traditional ON/OFF control

　　2. Humidifier: UL shaped stainless steel electroplating heater, using a safe saturated vapor humidification system to automatically calculate high-precision PID+SSR control (calculation cycle: 1-4 seconds can be set), so that its heat loss is equivalent to the heating amount, thus saving about 30% electricity compared to traditional ON/OFF control

　　3. Waterway system: The waterway and circuit are structurally independent, improving the reliability of equipment operation; The progressive water replenishment floating ball control valve has dual functions of low water level alarm and automatic water replenishment, making humidity control more accurate and stable; Observation tube for water level in the water tank and alarm prompt function for water shortage.

　　4. Temperature measuring body: 2 pieces of PT 100 Ω made of DIN specification PSI 4.8mm SUS # 304 stainless steel. The humidity meter is resistant to high humidity and has a response time of only 2 seconds after long-term wetting.
