Weld purge monitor

The hand held, battery driven monitor reads accurately down to 10ppm and, believes the company, it is probably the lowest cost weld purge monitor of its kind, even though it contains an internal electro-mechanical pump for drawing samples of gas automatically over the sensor before discharging it to atmosphere.

The lifetime sensor eliminates the need for changing cells once every year or so, subject to the type of usage the "wet” cells receive. Alarm signals can be given by the PurgEye 200 to show when the purge gas level is within or outside the preset range.
