EDS3-104C

INFRARED CO2 CONTROLLER DATA SHEET This is a non-dispersion type infrared CO2 gas analyzer. It accurately measures the concentration of CO2 gas in the air, indicates the result and simultaneously outputs an analog signal. Since upper and lower limit alarm functions are standard it can also be used as a controller. This instrument is suitable for use as a CO2 meter in green houses, building ventilation systems, CA (Controlled Atmosphere) storage facilities, and so on. ZFP9 FEATURES 1. 2. 3. 4.

Use two-core shielded cable for the output signal cable in order to avoid the influence of inductive noise. Be sure to connect shielded wires to the ground terminal. Keep the output signal cable away from the power line and alarm contact output line. The product conforms to the requirements of the Electromagnetic compatibility Directive 89/336/EEC as detailed within the technical construction file number TZ734574. The applicable standards used to demonstrate compliance are : EN 50081-1 : 1991 CLASS A Conducted and Radiated emissions EN 50082-1 : 1992 Radiated immunity, ESD and FBT ZFP 3 ZFP9 Caution on Safety *Before using this product, be sure to read its instruction manual in advance.
