1 measurement channel 
1 temperature channel

A high resolution graphic screen with white backlight indicates all measurements and operating parameters such as temperature, date and time. 
Multi-point (1...5) calibration of pH electrodes with any of eleven pre-programmed and five user specified buffer tables. 
Multi-point (1...3) calibration of conductivity electrodes for increased linearity with any of three pre-programmed or three user specified standard tables.
Multi-point (2...5) calibration + blank correction of ion-selective electrodes.
The display guides you at any moment in the language of your choice (English, Dutch, French, German). 
All necessary GLP-procedures are on board. 
Operates with a galvanic oxygen electrode requiring no polarisation time. 
Password protection prevents any unauthorised access to the instrument. 
Three year warranty. 
Storage memory for up to ****0 values + date and time. 
Two-way communication with any computer using USB (galvanically isolated). 
Robust dust and splash-proof cabinet. 
Operates on the mains (**0/**0 VAC), rechargeable batteries or 9...*5 VDC. 
Optional *2 V car adaptor permits these laboratory meters to work in a car. 
Freely downloadable data acquisition software enables to view, store and edit the measurements in your computer.
