PD-12 is an ATEX certified gas detector with a built-in pump which makes it an excellent choice in areas such as depots, tunnels and industrial facilities. With a PD-12 it is possible to detect many different gases – flammable gases, toxic gases, hydrogen and helium through the various sensor options hot-wire, catalytic combustion and thermal conductivity. The instrument can be used as it is in its simplicity since there is a display on the device that indicates both the gas concentration and alarm. It is also possible to connect a flash or sound alarm directly via the 4-20mA output. Even for large systems with over 100 sensors with advanced control of ventilation, shutdowns of equipment and gases PD-12 is a safe and cost effective alternative.
