TPS 90 Series

TPS 90 Series



The TPS 90 range of Field Lab Analysers provide a complete, portable measurement solution for several of the most important water quality parameters.

Why choose TPS 90 Series Water Quality Meters?


All measurements are shown simultaneously on the 80 character display. There is no need to change modes to check any of your vital data. The user-friendly menu system guides the operator through all operations such as calibration, setup etc. Full text help and error messages are provided along the way.


The 90 series is designed for rugged field applications in wet environments. The case, keypad and connectors are rated to IP65.

Good Laboratory Practices

To comply with GLP guidelines, the date, time and results of the last calibration are stored in memory, along with the unit's serial number. This data can be displayed or sent directly to the RS232 port. Warning of failed calibration is provided. All readings stored in memory are stamped with the date and time.

Notepad Function

A standard feature of the 90 series is the Notepad function. Up to 8100 sets of readings (depending on model) can be recorded for later review. These can be downloaded to a printer or computer via the RS232 port. For added functionality, the user is able to enter up to two additional items to be tagged on to the reading. Many operators use this function as a pond or site identifier, depth or readings from other instruments.


Automatic datalogging provides the capability to automatically record up to 8100 sets of readings (depending on model) at user-set intervals. The unit remains dormant between readings and only wakes up whenever a reading is due. Battery life is considerably improved with this facility.

RS232 Serial Port Interface

All recorded data can be downloaded directly to a Printer or Computer with the standard RS232 port (cable sold separately). With the WinTPS communication software, many instrument functions can be controlled from the computer. This makes the units ideal for remote monitoring.

The 90 Series is proudly designed and manufactured in Australia. The TPS Quality System has been certified in accordance with the AS/NZS ISO 9001 standard.
