ATI’s Series PQ45 is the answer to the need for a rugged field deployed package capable of measuring and recording water quality data in a variety of operating environments. It is ideal for short term recording of specific parameters such as Free Chlorine and pH in potable water.
Series PQ45 Systems are available for monitoring various components in water. The available measurements are shown in the listing below. Free chlorine, combined chlorine, dissolved ozone, and residual chlorine dioxide systems are supplied with a “Sensor Keeper” to maintain sensor polarization, even when the monitor is turned off.
Portable monitoring systems operate continuously for up to 30 days on 2 internal C-cell batteries. Rechargeable C-cell batteries may be substituted for the standard alkaline batteries, but the duration of operation will be different depending on the batteries used. As an option, the internal batteries may be eliminated and a terminal block is supplied for connection to an external 5-17 VDC power supply. This option allows easy adaptability to solar power systems.
Complete PQ45 systems are supplied in a durable carrying case with provision for user supplied locks to protect from tampering. Sensors and flowcells are mounted on an internal hinged panel for easy access. The optional data logger is located on the front of the panel and is removable by simply plugging input cables. The optional data logger contains it’s own internal battery suitable for about 6 months operation.
Water connections are made using flexible inlet and drain tubing. Fittings are supplied for the user to adapt tubing to piping systems. Other than a shut-off valve at the sample point, no additional flow controls are required. The PQ45 contains a flow regulation device that will maintain sample flow at about 400 cc/min at any inlet pressure from 5-100 ps. An internal V-strainer protects the flow control from any large particles and the fittings supplied for liquid connections contain internal valves that stop flow as soon as the fitting is disconnected. A 20 foot length of tubing is included.
The PQ45 data logger has an optional software package for programming the data logger, downloading data and displaying data in graphical and tabular form.
Each Series PQ45 system comes with a supply of spare parts for routine maintenance. These parts are conveniently stored behind the internal hinged panel and are sufficient for regenerating the sensor at prescribed intervals through the first year of operation.
