Technical and general information
Eldar CO2 controller is another product of Eldar Shany Technologies's family of sophisticated control products for agricultural use, well-known all over the world.
Eldar CO2 can be used as a stand-alone controller, by determination of 2 set points, or as an analog sensor, linked to a whole climate control or data logging system.
Eldar CO2 can be integrated also with Eldar Multi CO2 scan and control system.
Together with Eldar Shany Technologies's climate controllers, a single CO2 controller can monitor and control a large number of spaces (normally up to 10-12).
Eldar CO2 is especially designed for hard conditions and has already proved itself as most accurate and stable in various conditions, such as greenhouses, mushroom chambers, poultry houses, cooling chambers etc.

The monitor
The heart of Eldar-CO2 is the monitor unit. The unit is a high performance infra-red gas monitor designed for integration in wide range of analysis, measurement and control instruments. The unit offers all the advantages of established infra-red absorption techniques.
Accurate
The sensor head is based on a patented technique which provides true, dual wavelength infra-red sensing with no moving parts. The result is low drift, high accuracy monitor with fast response time and low power consumption.
Reliable
The monitor employs state-of-art mount technology and a high efficient switched mode power supply to ensure reliability and to minimize power consumption and overall size. The reliability is further enchanted by elimination of all moving parts and consumables.
Versatile
An industry standard 4..20mA linear analog output is provided to offer a compatibility with wide range of instruments.
