1 X Digital LED PID Temperature Controller Thermometer Heating Cooling Control SSR 2 Alarm Relay Output TC/RTD, Standard

This is a dual display universal digital programmable temperature controller that supports many types of thermocouple sensor. It can be powered by AC/DC.

Features:
Dual LED display, settable unit for Fahrenheit(F) and Celsius(C).
The temperature display range is -199~1800C, accuracy: 0.3%F.S2dgt.
Auto-tuning PID adjustment to choose for different applications or environments to be controlled.
Available for many TC or RTD input, precise, stable and simple for use.
Widely applied to auto system in line of light industry, chemistry, machine, metallurgy(etc.) to control the temperature.

Notice:
R: RELAY; S: SSR; N: None
RNR model represents the main control is RELAY, with only 1 alarm(RELAY).
SSR model represents the main control is SSR, with 2 alarms(SSR and RELAY).
