D230

1.      Overview:

Modular system:

-          Built in a standard 19" rack and cabinet the central unit accepts up to 7 modules. Different modules can be mixed in one unit.

-          There are two modules available: with four pH/mV/Ion/O2+ four emperature channels or with four conductivity/TDS + four tem-perature channels.

-          All parameters including set-up, calibration and display are control-led 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 of 448.

pH:

-          One- or two-point calibration.

-          Selectable resolution from 0.001 pH to 0.1 pH.

-          Automatic calibration with any of nine pre-programmed and two user specified pH buffers.

mV:

-          Features mV calibration for accurate ORP measurements.

-          Selectable resolution from 0.1 mV to 1 mV.

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 calibration, no zero calibration required.

-          Manual salinity compensation 0-40.

-          Manual air pressure compensation 800-1200 hPa.

Temperature:

-          Manual or automatic temperature compensation.

-          Calibrates temperature probe for quality measurements.

Conductivity:

-          One-point calibration.

-          Use a 1 cm^-1electrode (standard) to measure from 0.1 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 reference 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 capaci-tive component of the electrode and its cable (avoid the use of long

cables!).

Special features:

-          Three year warranty.

-          No electrical interference between electrodes in the same solution.

Data acquisition:

-          The software package supplied with the D230 is specially designed to

-          control, collect and store data. Runs under Windows™ 2000 or higher.

-          All channels are processed at the same time, each in its own win-dow.

-          The software automatically detects the maximum number and type of available channels.

-          Data is collected on-line at a programmable interval determined by the program (4 s ... 24 h).

Table:

-          Data is always stored in a table.

-          Each module has its own programmable table containing an un-limited 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 trans-ferred into spreadsheets.

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.

§  date and time.

§  name of the 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 easily access the most useful functions.

-          The contents of each window can be transferred to other programs by using a copy function.

-          Tile or cascade the windows and arrange the icons fully automati-cally or rearrange them manually.
