Modular CO2 transmitter for demanding OEM applications

(Engerwitzdorf, 21.01.2014) The modular CO2 transmitter EE870 from E+E Elektronik is designed for maintenance-free use in demanding OEM applications. It offers various analogue outputs, Modbus interface, and a wide range of AC and DC supply voltage ranges.  

The compact, interchangeable probe measures CO2 concentrations up to 10,000 ppm and can be replaced within seconds without the need of calibration or adjustment. The user can change the measuring range of EE870 by simply plugging in another probe.

The probe is based on infrared technology (NDIR) and uses a dual wavelength auto-calibration procedure. Thus, it is completely maintenance free and highly resistant to environmental influences.

Thanks to the factory multipoint CO2 and temperature adjustment, temperature compensation ensures excellent measurement accuracy over the entire operating range of -40... 60°C.

Due to the probe’s very high resistance to pollution, the EE870 is particularly suitable for use in harsh conditions, such as greenhouses, stables, fruit and vegetable storage facilities, hatchers and incubators.

Advantages at a glance:

• Excellent long-term stability via auto-calibration
• Highest measurement accuracy due to temperature compensation
• High resistance to pollution thanks to the IP65 housing and replaceable filter
• Easy installation and service due to modular design
