Introduction
The instrument series HD2205.2, HD2206.2, HD2256.2, HD2259.2, and
HD2569.2 is made up of bench top instruments for electrochemical measures:
pH, conductivity, dissolved oxygen, and temperature. They are fitted with a large backlighted LCD display.
The HD2205.2 is equipped with two BNC inputs for the measurement of pH, mV, redox potential ( ORP) with pH or redox electrodes, or electrodes with separate
reference, and one input for combined pH/ temperature probes fitted with SICRAM module.
The HD2206.2 measures conductivity, resistivity in liquids, total disssolved solids ( TDS) , and salinity with combined 4-ring and 2-ring conductivity/ temperature
probes. The conductivity probes can have a direct input or with SICRAM module. The inputs are separate.
The HD2256.2 measures pH, mV, redox potential ( ORP) with pH, redox electrodes or electrodes with separate reference. Conductivity and resistivity in liquids, total dissolevd solids ( TDS) and salinity with combined 4-ring and 2-ring conductivity/ temperature probes. The conductivity probes can have a direct input
or with SICRAM module. The inputs are separate.
The HD2259.2 measures pH, mV, redox potential ( ORP) with pH, redox electrodes or electrodes with separate reference; the 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.
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.
Al 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 conductivity probe calibration can be performed automatically with automatically
detected conductivity calibration solutions: 147¼ S/ cm, 1413¼ S/ cm, 12880¼ S/ cm or 111800¼ S/ cm or manually with calibration solutions having different
values.
⢠The dissolved Oxygen probe' s quick calibration function guarantees timely correctness of the performed measurements.
⢠Conductivity, dissolved oxygen and temperature probes fitted with SICRAM
module can store factory and calibration data inside.
The instruments of the series HD22⦠are datalogger, they memorize up to 2, 000 samples of data:
⢠pH, mV and temperature: HD2205.2
⢠conductivity or resistivity or TDS or salinity and temperature: HD2206.2
⢠pH or mV, conductivity or resistivity or TDS or salinity and temperature: HD2256.2,
⢠pH or mV, concentration of dissolved oxygen or saturation index and saturation index and temperature: HD2259.2,
⢠pH or mV, conductivity or resistivity or TDS or salinity, concentration of dissolved
oxygen and temperature: HD22569.2.
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 ( Sâ 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.
The instruments have IP66 protection degree.
