Product Description

RS485 Integrated SHT3x Humidity Temperature Transmitter Box 

VTH400-T 4-20mA output Integrated Humidity Temperature Transmitter adapts to DC 5V-30V power supply voltage, and its low power consumption design greatly reduces the influence of self-heating. There are two installation methods, mounting and screw installation greatly facilitate quick installation in various places. The chip can be made into a built-in transmitter box or external in probe,meanwhile the probe has PE, or metal probe can be selected. Users can choose according to their own needs.


This transmitter is widely used in HVAC, computer room, weather stations, data center, greenhouse and so on. The transmitter can be customized with LCD display or without display. Other than integrated type, you can also customize the transmitter with a SHT probe such as Copper Sintered or Stainless Steel Probe and cable based on your application and working environment. With that, you can customize the SHT sensor cable length to suit your installation, and allow the transmitter with a display to be installed outside the room.
