Datalogging
The smartCHEM-pH comes with a 2730 reading memory. Readings can be recorded manually, or automatically logged at preset intervals.

RS232 Computer Interface
The capabilities of the smartCHEM-pH have been expanded with the RS232 port, which is standard equipment (cable sold separately). All readings stored in memory can be downloaded to an RS232 printer or PC. The RS232 port also allows the smartCHEM-pH to log directly to the printer or PC. WinTPS Communication software for Windows 3.1 or 95, 98 & ME is available.

Automatic Stability Function (ASF)
ASF adds an extra level of versatility to the smartCHEM-pH. When ASF is activated, the smartCHEM-pH monitors all parameters that are currently in use. When ALL parameters become stable, the readings are frozen on the display. ASF is automatically activated with extra fine settings during calibration, to ensure the most accurate possible results for the user.

ASF can also be used during Manual and Automatic Datalogging. When used during Automatic Datalogging, the smartCHEM-pH will log until a stable end-point is reached for all parameters, then stop logging.

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

Easy to use
The smartCHEM-pH has a 240 x 64 dot graphic display. It features a user-friendly menu system, making the handbook virtually unnecessary. Full-text help and error messages are provided. All readings and messages are provided in large, bold characters.

Automatic Calibration
Where necessary, the user is able to define the standards to be used for calibration. For pH calibration, the smartCHEM-pH is programmed to automatically recognise the most popular buffers, making calibration a breeze. Any non-standard buffer value can be entered during calibration. 

Karl Fischer Measurements
A polarisation output is provided for Karl Fischer moisture titrations. 

Reliability and Service
The smartCHEM-pH is fully waterproof to IP65, so it is suitable for even the harshest laboratory or factory environments.
