HD2105.1 pH meter Thermometer, Storage of maximum, minimum, average value, RS232 C output for data transfer in real time to a PC or printer. Functions: REL, HOLD and auto power off which can be disabled, IP 67 protection degree.
HD2105.2 pH meter Thermometer Datalogger which stores the maximum, minimum, average value and can store up to 34.000 samples. RS232 C/ USB output for data transfer in real time to a PC or printer. Functions: REL, HOLD and auto power off which can be disabled, IP 67 protection degree.

HD2105.1 and HD2105.2 are portable instruments
with a large LCD display.
They measure the pH and the redox potential
(ORP) in mV.
Temperature measurement using Pt100 or Pt1000 immersion, penetration or contact probes.
The electrode calibration can be carried out on one,
two or three points and the calibration sequence
can be chosen from a list of 13 buffers.
The temperature probes are fitted with an automatic detection module, with the factory calibration settings already being memorized inside.
HD2105.1 and HD2105.2 models are fitted with an
RS232C serial port and can transfer the acquired measurements in real time to a PC or to a portable
printer.
