The PQ45 portable monitor and data-logger system is easy to set up, even in remote location to provide short-term data on residual chlorine and pH, recording it to an on-board data logger.

The software that is provided with the system enables data to be easily downloaded to a laptop or computer for analysis.

The monitor has built in flow and pressure controls to minimise external requirements. The connections are made through self-sealing fittings that isolate the flow as soon as they are disconnected.

Mounted in a sealed, lockable case, the PQ45 monitor can operate for up to 30 days from two C-cell alkaline batteries. It can also operate from external power supplies from 5-17 VDC or from a small solar power system.

Portable monitor systems are also available from ATI for dissolved ozone, residual chlorine dioxide, dissolved oxygen and conductivity.
