The 90-C is a highly functional, multi-range instrument for field measurements of Conductivity, TDS and Temperature. Full Automatic Temperature Compensation is provided. The 90-C has special circuitry to enable it to be used with long cables for bore holes and deep water bodies. Cables up to 100 metres may be used.
User-friendly
Conductivity/TDS and Temperature are shown simultaneously on the 80 character display. 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.
Waterproof
The 90-C is designed for rugged field applications in wet environments. The case, keypad and connectors are rated to IP65. The unit has been used successfully in the Antarctic, which is as extreme as any climate can get.
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-C is the Notepad function. Up to 9990 readings 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 site identifier, depth or readings from other instruments.
Datalogging
Automatic datalogging provides the capability to automatically record up to 9990 sets of readings 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. Our aim is to provide you with the best quality, service and value for money. The TPS Quality System has been certified in accordance with the AS/NZS ISO 9001 standard. Since 1968, TPS has built a reputation for excellent backup service that is second to none.
