Samwon Thermostat Temperature and Humidity meter - SU-1133BH

2 Relay output, Thermistor + Humidity input sensor, Attach sensor


The SU-1133BH is the Samwon digital temperature and humidity controller that is ideal and accurate tool for measuring and controlling both temperature and humidity at once . This thermostat features 2 screens, 1 ON/OFF relay output for temperature control, and 1 ON/OFF relay output for humidity control. The input sensor are thermistor  and humidity sensor, and the first and second outputs are relays that can operate on both AC (100~240V) and DC (12V, DC24V optional).

Other important features of SU-1133BH include the ability to calibrate the input values, change the relay mode to H to increase the temperature and humidity and C and D to decrease the temperature and humidity, adjust the cut-off and connection band of the relays, and the delay time of the relays.

This automatic temperature controller provides:

  • External Dimension: (W) 78mm × (H) 138mm
  • Thermistor + Humidity Input sensor
  • 2 Relay output
  • -50 ~ 99.9 ℃ Temperature measure range
  • 0 – 100 % RH Humidity measure range
  • F.S 0.3%, ±3% Precision
  • Controller installation environment conditions:

                             Ambient temperature: 0 ~ 50℃

                             Ambient Humidity: Less than 85% RH

  • Supply voltage: AC 100 ~ 240 V (50/60Hz) ± 10%

Industries / applications

  • The incubator
  • The greenhouse
  • The Pool

Series Information

Samwon SU1133 Series

Temperature and Humidity controller

The Samwon SU1133 series is a specialized series of temperature and humidity controllers. They go as low as -50℃ to as far as 200℃.

SU1133 Series Main features

  • Thermistor / Thermistor+Thermistor / Thermistor+HUMIDITY Input sensor
  • Attach Sensor
  • Temperature control via a SV value (SU-1133t)
  • Control via a sensor deviation : Operated when the value detected by 2 kinds of sensors is different from the setting value (SU-1133tt)
  • Thermistor + HUMIDITY Control (SU-1133th)
