Measure ambient temperature (Tamb) from -40 to +80 degrees Celsius and relative humidity (RH) from 0 to 100%, and wirelessly transmit them both to a wireless receiver hub for distributing to other instrumentation via analogue output, digital coms, or a mobile network.
The IWTRhT belongs to the IW series of wireless measurement products, and can be used alongside a suite of complementary wireless transmitters for different measurement types, and is fully compatible with all IW series wireless receivers.
Product Features
- Measures Tamb & RH
- 0.5°C Tamb accuracy
- 3% RH accuracy
- -20 to +80°C Tamb range
- 0 to 100% RH range
- Up to 500 m line-of-site range (depending on receiver)
- User-selectable transmission update rates
- Analog output, RS-232/485, Ethernet, USB, cellular network receivers
Product Description
The IWTRhT wireless ambient temperature & relative humidity sensor is battery powered and can be installed up to 500m away from the wireless receiver unit.
Monitor and log the local temperature and relative humidity in multiple locations using the user interface dashboard provided for each type of wireless receiver hub.
Each wireless Tamb & RH sensor is compatible with a choice of wireless receivers to transmit the temperature and humidity readings via an analogue output, Ethernet TCP connection, RS232/RS485 Modbus RTU serial interface, or a 2G/3G/4G mobile cellular network.
