pH - mV - Ion - Conductivity - Resistivity - TDS - Dissolved oxygen - Temperature

Modular System

• Built in a standard 19 inch rack + cabinet the central unit accepts up to 7 modules. Different modules can be mixed in one unit.
• There are two modules available: D291 & D292
• D291: 4 pH/mV/Ion/dissolved oxygen + 4 temperature channels,
• D292: 4 conductivity/TDS + 4 temperature channels.
• Up to 16 units can be combined with each other to increase the number of channels up to 448.
• All parameters including set-up, calibration and display are controlled through any computer via a single RS232 connection.
• Up to  16 units can be combined with each other to increase the number of channels to a maximum

pH

• One- or two point calibration.
• Selectable resolution from 0.001 pH to 0.1 pH
• Automatic calibration with any of 9 pre-programmed and 2 user specified pH buffers

mV

• Features mV calibration
• Selectable resolution for accurate ORP measurements.

Ion

• Direct concentration measurement.
• Shows concentration in any unit.
• Ion mode is easily calibrated with any two standards and a blank correction.

Dissolved oxygen

• Selectable resolution from  0.01 mg/l (0.1%) to 0.1 mg/l (1%)
• Rapid air calibrationn, no zero calibration required.
• Manuel salinity compensation 0-40
• Manuel air pressure compensation 800-1200 hPa.

Temperature

• Manuel or automatic temperature compensation .
• Calibrates temperature probe for quality measurements.

Conductivity

• One point  calibration
• Use a 1 cm^-1  electrode(standard) to measure from 0.01 µS/cm to 200 mS/cm.
• Use a 0.01 cm^-1  electrode to measure from 0.001 µS/cm to 2 mS/cm.
• Use a 0.1 cm-1  electrode to measure from 0.01 µS/cm to 20 mS/cm.
• Use a 10 cm-1  electrode to measure from 1 µS/cm to 2000 mS/cm.
• Selectable refernce temperature: 20° or 25°C
• Automatic calibration with any of three preprogrammed and three user specified standard solutions.
• Accurate low conductivity measurements by eliminating the capacitve component of the electrode and its cable (avoid the use of long cables!).

Special features

• Three year warrenty
• No electrical interference between  electrodes in th e same solution.

Data acquisition

• The software package supplied with the D230 is specially designed to control, collect and store data. Runs under WindowsTM 2000 or higher.
• All channels are processed at the same time, each in its own window.
• The sofware automatically detects the maximum number and type of available channels.
• Data is collected on-line at a programmable interval determined by the program (4s...24h).

Table

• Data is always stored in a table.
• Each module has its own programmable table containing an unlimited number of lines (maximum depends on available computer memory).
• Comments can easily be added to each  line in a special information column.

Starting

• Data-logging can start/stop automatically or at a programmable date/time
• Data-logging can be stopped or continued at any moment.

Files

• All data is saved in a user defined file. Just open the file to view, process or print the stored data.All measurements are saved in CSV format which is easily transferred into spreadsheets.
• All data is saved in a user defined file. Just open the file to view, process or print the stored data.

Graphs

• Graphs are generated using automatic or user defined settings.
• The number of visible  values can be changed at any time.
• Programmable alarm limits for each graph allow to print a report  indicating when limits have been exceeded.
• Shows statistics about minima, maxima, averages etc..

Settings

• Languages: English, Dutch, or French
• The style of each window can be set up separately.
• Choose fonts, colours etc...
• Documented printouts will show:-file name--name of operator-- name of the company-- name of the division-- optional notes by the operator.
• All settings are stored in a configuration file and automatically recalled when opening the program.

Functions

• All functions are accessible through the menu.
• Only valid options appear in the menu to eliminate set-up errors.
• Special buttons, icons and short-keys allow the user to easilly access the most useful functions.
• The contents of each window can be transferred to other program by using a copy function. Tile or cascade the windows and arrange the icons fully  automatically or rearrange them manually.
