Model AP-IE/MC-130 is a single range salinometer indicator and controller for use on distillation plants. The Aqua Purometer is now finding wide use in international applications calling for dump valve control of a distillation plant. These instruments use proven solid state circuitry housed in a rugged cabinet to provide an economical and straightforward approach to marine potable water control.

The Aqua Purometer AP-IE / MC-130 monitor system is available in 0-10 GPG and/or 0-100 PPM of chlorides in sea salt. Temperature compensator housed internally in the salinity cell automatically corrects all meter readings. Alarm and dump functions are adjustable across the entire range of normally acceptable potable water by an internal screwdriver control. During the set point adjustment procedure, the set point is displayed on the meter permitting clear adjustment. Note that the setpoint is enclosed within the panel meeting US public health requirements.

The cabinet is made of welded construction of sturdy stainless steel. A hinged front door provides access for inspection or adjustment. Servicing is further facilitated by the use of plug-in replacements for the most-serviced components. A rubber gasket provides a water resistant seal around the cabinet door. The cabinet is designed for bulkhead or console mounting P/N 18479 (with an optional kit). The meter is a rugged, dependable type with an easily read scale.

The salinity cell is the popular finger electrodes probe with shoulder to match needs of existing European style evaporators/distillation plant fitting. The metric style cell attaches to the existing piping, its coupling nut and existing gasket.
