In decades of digester and engine operation we have seen a large number of switches and sensors the good and the bad. We now only sell the units below. Fit these to your wet condensing acidic biogas site and we will still sleep soundly knowing they will operate year after year - however if you need the security of a spare or two - well there are only two kits, a sealed microswitch and a kit containing a new diaphragm and 'o' ring. These are in the spares warehouse section items 90,91 and 92.
