• The housing contains a diaphragm, a calibration
       knob and a snap-acting SPDT switch.

  • The 2 sample connections located on each side
        of the diaphragm accept 6.35mm(0.25")OD tubing

  • An enclosure cover guards against accidental
       contact with the live switch terminal screws and
       the set point adjusting knob.The enclosure cover
       will accept a 12.7 mm (0.5") conduit connection    or M20 connection.
