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.
