Large temperature Humidity Display

TRH-3305 Temperature and humidity display billboard:
Large LED display thermohygrometer is a wall-mounted or hanging measuring instrument developed according to foreign advanced technology and customer requirements. It has a large LED display that can display temperature and humidity at the same time,
External temperature and humidity sensor
The sensor is separated from the display billboard, sense
The actuator cable is 3 meters long and can flexibly measure the monitoring area.
The precision temperature and humidity sensor has a small error and can be used for precision monitoring
environment, temperature error specification of only 0.5 °C and humidity of 5 %RH.
Compensates for temperature and humidity measurements
When the sensor is gradually aging, it can be repaired digitally to compensate for the error
Value, which delays sensor usage time
