D230
pH - mV - Ion - Conductivity - Resistivity - TDS - Dissolved oxygen - Temperature

4...28 independent channels for all measurements

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: 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. 
All necessary GLP-procedures are on board. 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 window. The software automatically detects the maximum number and type of available channels. 
Data is collected on-line with a programmable interval (4 s ... 24 h).
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. 
Password protection prevents any unauthorised access to the instrument.
