Introduction
The
HD 98569
is a multiparameter portable instrument and datalogger for electrochemical
measurements:
pH
,
conductivity
,
dissolved Oxygen
and
temperature
. It is fitted with a large
backlit LCD display.
The instrument measures:
• pH
,
mV
,
redox potential
(ORP) using pH, redox electrodes or combined pH/temperature
probes complete with SICRAM module;
•
conductivity
,
liquid resistivity
,
total dissolved solids
(TDS) and
salinity
using combined 4-
ring and 2-ring conductivity/temperature probes with SICRAM module;
• concentration of dissolved Oxygen
in liquids (in mg/l),
saturation index
(in %) and
temperature using SICRAM combined probes of
polarographic
, with two or three
electrodes, and
galvanic
type with integrated temperature sensor.
The immersion, penetration, or contact Pt100
temperature
probes with SICRAM module can be
connected to the instrument.
•
The pH electrode calibration can be carried out on a minimum of one to a maximum of five
points, and the calibration sequence can be chosen from a list of 8 buffers. The
temperature compensation can be automatic or manual.
•
The calibration of the conductivity probe can be automatic, by recognition of standard solutions:
147
μ
S/cm, 1413
μ
S/cm, 12880
μ
S/cm, 111800
μ
S/cm or manual with different solutions.
•
The dissolved Oxygen probe's quick calibration function guarantees timely accuracy of the
performed measurements.
•
The pH, conductivity, dissolved Oxygen and temperature probes are fitted with a SICRAM
module, with the factory calibration settings already being memorized inside.
The HD 98569 is a
datalogger
. It stores up to 2000 single screens (labels) and up to 9000
samples in continuous recording of: pH or mV, conductivity or resistivity or TDS or salinity,
dissolved Oxygen concentration, saturation index, and temperature.
The data can be transferred from the instrument connected to a PC via the multistandard RS232C
serial port or the USB 2.0-1.1 port.
If equipped with the Bluetooth
HD22BT
option, the HD 98569 can send the data to a PC fitted with
the USB/Bluetooth HD USB.KL1 converter, to a printer with a Bluetooth HD40.2 interface, or to a
PC fitted with a Bluetooth input, without the need of any connection.
The RS232C serial connection can be used for direct printing of the labels using a 24 column
printer (HD40.1 or HD40.2).
The
DeltaLog11
dedicated software (vers. 2.0 and later) allows management and configuration of
the instrument, and data processing on the PC.
