Temperature – pH Meters

Jan 26, 2012 

The HD2105.1 and HD2105.2

are portable instruments with a large LCD display. They measure the pH and the redox potential (ORP) in mV. They measure the temperature 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 equipped with an automatic recognition module and factory calibration data are stored inside.

The HD2105.2 is a datalogger. It stored up to 34,000 pH and temperature samples which can be transferred to a PC from the instrument connected via the multi-standard RS232C serial port and USB 2.0. The storing interval, printing, and baud rate can be configured using the menu.

The 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. The Max, Min and Avg function calculate the maximum, minimum or average values.
Other functions include: the relative measurement REL, the Auto-HOLD function, and the automatic turning off that can also be excluded.

The instruments have IP67 protection degree.
