Gas detectors for LABORATORIES

The special detection system “LABORATORIES” is designed for the detection and monitoring of parking and garage spaces where a critical concentration of explosive or toxic substances can occur. It can be used to measure the concentration of up to six most used gases (CH4, C4H10, H2, Gasoline vapor, CO, NO2). The transmitters convert the measured concentration into a unified 4-20mA and RS485 (DEGA protocol) / RS485 (MODBUS) current signal. There is a possibility of connection to evaluation control panels DEGA UPA III, DEGA UKA III, and DEGA UDA III. A significant benefit of the system is the excellent price-quality ratio.

EX Zone 1Transmitter is not designed for detection and monitoring in industrial and commercial premises which required ATEX certification. For ATEX application we recommend transmitters DEGA NS II (zone 2) or DEGA NS III (zone 1).

Basic Gas Detection Methods:

CL – catalytic sensor (Pelistor)
Works on the principle of catalytic combustion – the gas concentration is measured in accordance with the amount of heat released during a controlled combustion reaction. The reaction is prompted by a suitable temperature and the presence of a catalyst. These sensors can be used for the detection of a wide range of combustible gases. The sensors are characterised by their fast response, long life and high degree of stability. For their proper functioning they require at least 10% of the oxygen in the air. The transmitter sensor is sensitive to compounds of silicon, the introduction of which can result in poisoning of the sensor.

EL – electrochemical sensor
This operates on the principle of measurement of the change in the electrical parameters of electrodes placed in electrolyte, due to the redox reaction of detected gas on their surface. These sensors have a favourable selectivity and the capacity to detect very low concentrations of gases. In the DEGA systems they are utilised primarily for the detection of toxic gases.
