- 1 pH channel - 1 mV channel - 1 conductivity channel - 1 temperature channel A high resolution graphic screen with white backlight indicates all measurements and operating parameters such as temperature, date and time. Microprocessor controlled bio-electronic rH2 meter for the study of the biological water quality or illnesses in body fluids according to Vincent's method. Shows mV referred to the standard hydrogen electrode. Allows simultaneous measurement of all parameters in the same solution.Calculates the resistance (ohm) and the quantification of Vincent (µW). A high resolution graphic screen continuously indicates all measurements and operating parameters such as temperature, date and time. Multi-point (1...5) calibration of pH electrodes with any of nine pre-programmed and five user specified standards. Multi-point (1...3) calibration of conductivity electrodes for increased linearity with any of three pre-programmed or user specified standards. The display guides you at any moment in the language of your choice (English, Dutch, French, German). All necessary GLP-procedures are on board. Password protection prevents any unauthorised access to the instrument. Storage memory for up to 12000 values + date and time. Programmable recorder output. Two-way communication with any computer using USB. Operates on the mains (120/230 VAC) or 9...15 VDC.
