eyc-tech GS07 is a state-of-the-art non-dispersive infrared(NDIR)carbon dioxide(CO2 )transmitter. The
direct insertion design and miniature size make it easy to install in the ventilation duct.
eyc-tech GS07 provides measurement in analog outputs(0 … 10 V, 4 … 20 mA)and digital output(RS-485
Modbus RTU protocol).
With CO2 demand controlled ventilations, eyc-tech GS07 helps to save money by decreasing the energy
consumption while maintaining a healthier indoor climate

Note 1: The SO
2 enriched environments are excluded.
Note 2: In normal IAQ applications(at NTP). Accuracy is defined after minimum 3 weeks of continuous operation. The tolerance of the span calibration gas (2% unless otherwise requested)and test gas adds to the total uncertainty.
Note 3: The specifications are valid for the output load connected to ground G0. Other outputs and measurement ranges are available per request.
