HD2259.2 Laboratory Benchtop Meter. pH or mV, concentration of dissolved oxygen or saturation index and saturation index and temperature. 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.
HD2259.2 pH Meter
| Model | Description |
|---|---|
| HD 2259.2 | pH or mV meter. Concentration of dissolved oxygen. |
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 (Sprint-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.
