HD 22569.2 Laboratory Benchtop Meter. pH or mV, conductivity or resistivity or TDS or salinity, concentration of dissolved oxygen and temperature:
The HD22569.2 measures pH, mV, redox potential (ORP) with pH, redox electrodes or electrodes with separate reference; conductivity, resistivity in liquids, total dissolved solids (TDS) and salinity with combined 4-ring and 2-ring conductivity temperature probes with direct input or SICRAM module; concentration of dissolved oxygen in liquids (in mg/l) and saturation index (in %), using SICRAM combined probes of polarographic type with two or three electrodes and integrated temperature sensor.

Measured values:
pH - mV - χ - Ω - TDS - NaCl - mg/l O2 - %O2 - °C - °F

All models are fitted with input for the measurement of temperature with Pt100 or Pt1000 immersion, penetration or contact probes. The probes are equipped with an automatic detection module, with the factory calibration settings already being memorized inside.
The pH electrode calibration can be carried out on one or five points and the calibration sequence can be chosen from a list of 13 buffers.
The pH electrode calibration can be carried out on one or five points and the calibration sequence can be chosen from a list of 13 buffers Temperature compensation can be automatic or manual.
The instruments of the series HD22… are datalogger, they memorize up to
2,000 samples of data:

The data can be transferred from the instrument connected to a PC via the multistandard
RS232C serial port and USB 2.0. The storing parameters can be configured using the menu.
The RS232C serial port can be used to transfer the acquired measurements to a 24 column portable printer in real time (S’print-BT).
The instruments equipped with HD22BT (Bluetooth) option can transfer data
without any connection to a PC or printer fitted with Bluetooth input or through Bluetooth/RS232C converter.
The software DeltaLog11 allows instrument management and configuration, and data processing on PC.
