Hanwell RL4512 Wireless CO2 Transmitter

Hanwell RL4512 Wireless CO2 Transmitters are used for process monitoring of carbon dioxide as part of the Hanwell EMS data acquisition system.  The probe itself is the Vaisala GMP251 , also offered by Fluidic within our partner agreements.  CO2 monitoring is an important part of maintaining efficiency in many food and beverage applications.  Hanwell RL4512 transmitters are specifically designed for high CO2 applications, up to 20%.  For environmental systems, typically monitoring ppm levels of CO2 in offices, schools, warehouses etc, please contact our sales engineers at Fluidic.  We can offer a system using wall mounted Vaisala units fitted through Hanwell RL4809 wireless transmitters.
