The 740 Monitor includes capability for up to ten customer programmed user profiles, each defined by site specific calibrations to cater for differences in the effluents being monitored. A retrospective adjustment to the calibration for each site is also possible via a unique menu facility that enables a specific sensor output to be stored in memory at the same time as a liquid sample is taken. The gravimetric analysis of the suspended solids level in the sample is then returned to the monitor as the final calibration figure. Further site calibration enhancement is afforded by the ten-point look up table, allowing the monitor to accurately measure suspended solids in vast majority of applications.
The achievable accuracy and ease of use make the 740 Portable ideal for regular checking of suspended solids levels to process or legislated requirements in activated sludge plants, final effluent outfalls, treatment plant inlets, streams and rivers and as a secondary standard to check other on-line and portable instruments.
