Temperature and CO2 Sensor – RL5016/8 for Laboratories and Incubators

The RL5018 and RL5016 radio transmitters are suitable for accurate humidity and temperature monitoring and CO2 measurement typically for laboratories and incubators. The established Hanwell temperature humidity monitoring system makes use of this reliable transmitter for instant alarm notifications and around-the-clock data.

The RL5018 and RL5016 radio transmitters are not available for online purchases due to the radio system requirement. Customers can contact IMC if they want to know about the variable product options ideal for their applications.
