Specification

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/tempera-
ture 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 instrument ifs fi tted 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 fi ve 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 de-
tected conductivity calibration solutions: 147¼S/cm, 1413¼S/cm, 12880¼S/
cm, 111800¼S/cm or manually with calibration solutions having different
values.
• The dissolved oxygen probe’s quick calibration function guarantees long-
term correctness of the performed measurements.
• pH, conductivity dissolved oxygen and temperature probes fi tted with
SICRAM module can store factory and calibration data inside.
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 satura-
tion index and temperature.
The data can be transferred from the instrument connected to a PC via the
multi-standard RS232C serial port and USB 2.0-1.1.
The instruments equipped with HD22BT Bluetooth option can transfer the
data without any connection to a PC fi tted with USB/Bluetooth converter
HD USBKL1, or to the printer S’print-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 (S’print-BT).
The software DeltaLog11 (vers. 2.0 and subsequent ones) allows instrument
management and confi guration, and data processing on PC.
