This ZL-7903A controller is an industrial intelligent temperature and humidity controller.  You can connect the external SSR to realize bigger heating power rate, and with PID temperature control method. With touchable button and large LCD display, also convenient to operate and set up. Come on and try it, it will not let you down.

Features:
Three temperature control modes: relay up/down limit control, SSR up/down limit control and PID control. You need to connect the SSR by yourself, SSR limit control is able to set power rate when room temperature is close to setpoint.
Powerful functions: With the ventilation fan control functions, humidify or dehumidify contol, door open/close check and control and illumination control.
With the timer air exhaust control and timer eggs turning control, also with the power off memory function.
Multiple protection functions: With the temperature and humidity over limit warning and protection function and the temperature and humidity sensors fault warning and protection function.
Wide applications: Can be used for control of incubator, climate chamber, warehouse and so on places.
With two different humidity sensors: ZL-SHr05J, ZL-SHr05P for you to choose, please check before order.
