HD 98569 Portable multi-parameter data logger for electrochemical parameters measurement and logging.
The HD 98569 is a portable multi-parameter data logger for electrochemical measures: pH, conductivity,
dissolved oxygen and temperature. It is fitted 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 instruments equipped with HD22BT Bluetooth option can transfer the data without any connection to a PC fitted with USB/Bluetooth converter HD USBKL1, or to the printer Sprint-BT with Bluetooth interface or to a PC with Bluetooth input. The serial connection RS232C can be used for direct printing of labels with a 24 column printer (Sprint-BT).
The instrument ifs fitted with input for the measurement of temperature with Pt100 immersion,
penetration or contact probes with SICRAM module.
- The pH electrode calibration can be carried out on one or five points and the calibration sequence
can be chosen from a list of 8 buffers. Temperature compensation can be automatic or manual.
- The conductivity probe calibration can be performed with automatically detected conductivity
calibration solutions: 147μS/cm, 1413μS/cm, 12880μS/ cm, 111800μS/cm or manually with calibration
solutions having different values.
- The dissolved oxygen probes quick calibration function guarantees long term correctness of the
performed measurements.
- pH, conductivity dissolved oxygen and temperature probes fitted with SICRAM module can store
factory and calibration data inside.

HD 98569 The instrument can measure three electrochemical quantities at the same time: pH or ORP,
conductivity, TDS or
salinity, dissolved oxygen and temperature.
Three optoisolated inputs. Input 1: pH, ORP or temperature. Input 2:
dissolved oxygen or temperature.
Input 3: conductivity, total dissolved solids, salinity or temperature. It can measure,
store or download the
readings through the multistandard RS232C/USB2.0 serial port. The instrument is equipped with
four 1.5V
batteries, instruction manual, software DeltaLog 11, carrying case and SICRAM module pH471 with 1m
cable.
Connection and data download cables, calibration solutions, electrodes and probes have to be ordered
separately.
