Reliable and precise gas measurement systems for determining the concentration of toxic or combustible gases and vapours in potentially explosive environments

LogiDataTech supplies innovative gas measurement systems for directly determining gas concentration in a gas mixture. The explosion-proof MF420-Ex-2.1 range measures the concentration of toxic or combustible gases and vapours in an explosive air mixture at an ambient temperature range of 0-50°C. They operate by utilising either a pellistor or a specific electrochemical sensor. Calibration is a simple procedure and is carried out on-site using an alphanumeric display with the use of buttons, so the device does not need to be opened. The aluminium housing is suitable for wall mounting. The measured values are outputted via a linear current output (4-20mA) and the evaluation and further processing of the measured values are transmitted to a device connected downstream by the user. The instruments comply with the current European ATEX standard and are approved for operation in zones 1 and 2.
