Hanwell RL4000 RH/T Series for Accurate Temperature and Humidity Sensors

The RL4000 RH/T series of accurate temperature and humidity sensors from Hanwell are available in data logger and radio transmitter formats.

Hanwell RL4000RHT Wireless Humidity Monitor Range

The 4000RH/T series of radio transmitter units are considered the most flexible wireless humidity monitor units that are currently available on the market. All of these units are designed to be compatible with a variety of humidity and temperature probes in order to provide reliable and accurate measurement specifically chosen for the requirements of users.

Additionally, it is possible to wirelessly transmit temperature and humidity data directly to a local PC for immediate and automatic analysis and notification. Most wireless devices include the logging facility in order to guarantee against data loss in the event of radio communication loss.

A single 3.6 Volt AA Lithium battery is used to power the units, and users can replace this battery when needed. The battery life will depend on the method of data collection. However, this battery can last for up to 3 years, with notification of when a change is needed.
