Automatic Digital LED PID Temperature Controller Thermometer SNR 1 Alarm Relay Output TC/RTD Input

Features:
Dual LED display, settable unit for Fahrenheit(F) and Celsius(C).
Wide temperature display range: -199~1800C; Accuracy: 0.3%F.S2dgt.
Auto-tuning PID adjustment to choose for different applications or environments to be controlled.
Suitable for many TC or RTD input, precise, stable and simple for operation.
Widely applied to auto system in line of mechanism, chemical industrial, chinaware, metallurgy(etc.) to control the temperature.
Notice:
I: 4~20mA S: SSR/Logic N: None R: Relay
SNR model represents the main control is SSR, with only 1 alarm(RELAY).
