The RS PRO filter loss gauge is a general-purpose manometer, suitable for positive, negative and differential pressure measurements. This precision, clear plastic gauge has the benefit of giving a continuous display of the filter condition. There is no limit to the distance between the filter and where one mounts the gauge. This filter loss fluid manometer is supplied with pressure tubing, fixings, self-sealing duct connectors, 'Filter Clean' and 'Change Filter Now' self-adhesive labels, spare manometer fluid (S. G 0.8) and self-tapping fixing screws.
