KCO2.T.RH.x RS485 – KLQ.T.RH RS485
Multifunctional Channel Bus Units RS485
Application
The KCO2.T.RH.x RS485 or KLQ.T.RH RS485 with or without display multifunctional channel bus unit whose signal communicates via RS485 and by means of Modbus®- RTU records the CO2 content, the temperature as well as the relative/absolute humidity and/or the quality of the air, depending on the version.
