The 90 series is designed for rugged field applications in wet environments. The case, keypad and connectors are rated to IP65.
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.
A standard feature of the 90 series is the Notepad function. Up to 9340 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 pond or site identifier, depth or readings from other instruments.
Automatic datalogging provides the capability to automatically record up to 9340 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.
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.
