 TRH-3305 Larege Digital temperature and humidity display board:

The large LED display temperature and humidity meter 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 simultaneously display temperature and humidity,
External temperature and humidity sensor

The sensor is separated from the display board and the sensor
The sensor cable is 3 meters long, which can flexibly measure the monitoring area.

Precise temperature and humidity sensors with small errors can be used for precision monitoring
environments with a temperature error specification of only 0.5 °C and a humidity of 5 %RH.
Compensable temperature and humidity measurement value
When the sensor is gradually aging, the error can be compensated through digital correction
value, delay sensor use time


Widely used in museums, offices, hotels, restaurants, schools, conference rooms, waiting rooms, hospitals, factories, shopping malls, warehouses, indoor environments, etc.
