smartCHEM-D 1m bundle

The smartCHEM-D is a high performance, research grade Dissolved Oxygen meter. Salinity levels affect the solubility of Oxygen, so the smartCHEM-D also contains a full function Conductivity meter.

Datalogging

The smartCHEM-D comes with a 1489 reading memory. Readings can be recorded manually, or automatically logged at preset intervals.

RS232 Serial Port Interface

The capabilities of the smartCHEM-D 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-D 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-D. When ASF is activated, the smartCHEM-D 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-D 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.

A calibration alarm can be programmed to whichever parameters the user chooses. The alarm can be set for Daily, Weekly, 2 Weekly or 4 Weekly. The calibration alarm can also be switched off.

PIN Code Access

The Access Code is system is provided for those users who need to ensure the integrity of recorded data, calibration settings and so forth. The Access Code function will prevent anyone who does not know the code from entering the menu system. Keys that are available during normal measurement, (Store, Print, Autolog and F1 to F5 ) are still available without the Access Code. This means that others are still able to carry out day-to-day work.

Easy to use

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

Automatic Calibration

For Dissolved Oxygen calibration, the smartCHEM-D automatically detects whether the sensor is in a Zero DO2 solution or in air and calibrates itself accordingly. A ppM value can also be typed in in ppM mode, if the operator wishes to calibrate against a Winkler titration.

For Conductivity and TDS calibration, the user is able to define the standards to be used for calibration.

Dissolved Oxygen Stirrer Output

A 4. 5V DC output is provided for use with the YSI Self-Stirring BOD electrode. The output can be activated as required by the user , or automatically during Automatic Datalogging.

Reliability and Service

The smartCHEM-LAB is fully waterproof to IP65, so it is suitable for even the harshest laboratory or factory environments. TPS has been manufacturing top quality, reliable instruments and electrodes since 1968. The TPS Quality System has been certified in accordance with the AS/NZS ISO 9001 standard. Our service is also of the highest standard. Spares and accessories are always held in stock, and our modern service facilities ensure a rapid turn-around for maintenance and repair work.
