It's hard for me to find a sampling pump in a gas sampling system for analysis instruments. The requirements are as below:
1) Explosion-proof requirement (media: gas mixed with hydrogen);
2) Fit for 1/4"OD sampling line;
3) The max. discharge flow: no greater than 13 L/h.
These three conditions must be followed at the same time. Could anyone help me recommend a suitable sampling pump for hydrogen/oxygen analyzer use in the downstream?
