Electrochemical laboratory measuring instrument : pH, conductivity, redox, dissolved oxygen
Delta Ohm

The HD 98569 is a portable multi-parameter data logger for electrochemical measures: pH, conductivity, dissolved oxygen and temperature. It is fi tted with a large back-lighted LCD display.
The instrument measures:
* pH, mV, redox potential (ORP) with pH, redox or combined pH/temperature electrodes complete with SICRAM module;
* conductivity, resistivity in liquids, total dissolved solids (TDS), and salinity
with combined 4-ring and 2-ring conductivity and temperature probes
with SICRAM module.
* Concentration of dissolved oxygen in liquids (in mg/l), saturation index
(in %) using SICRAM combined probes of polarographic type with two or
three electrodes and integrated temperature sensor.
The HD 98569 is a data logger, it memorizes up to 200 single screens (labels) and up to 9000 samples in continuous storage mode: pH or mV, conductivity or resistivity or TDS or salinity, concentration of dissolved oxygen and saturation index and temperature. The data can be transferred from the instrument connected to a PC via the multitandard RS232C serial port and USB 2.0-1.1.
