VTH533-B Temperature and Humidity Transmitter
Integrated Probe Type

The VTH533-B features a standard industrial interface with either 4–20 mA analog output or RS485 digital signal output. It can be seamlessly connected to on-site digital display meters, PLCs, frequency converters, industrial control systems, and other equipment.

It is safe, reliable, aesthetically designed, and easy to install. The probe is directly integrated with the transmitter, eliminating the need for additional mounting components.

The HG803 is widely used in environments that require accurate temperature and humidity monitoring, including communication rooms, warehouses, archives, cultural relic preservation, floriculture, agricultural greenhouses, cement curing rooms, underground railways and tunnels, paper manufacturing, textiles, tobacco storage, and distribution cabinets.
