Price range: R4,152.00 through R5,543.00 ex vat

CO2 Transmitter – Overview

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

CO2 Transmitter – Features

Note 1: The SO2 enriched environments are excluded.
Note 2: In normal IAQ applications(at NTP). Accuracy is defined after a minimum of 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.
