Delta Ohm HD2105 pH, mV and Temperature Meter

The HD2105.1 and HD2105.2 are portable instruments with a large LCD display. They measure the pH, the mV, 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 manually or automatically 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.

The HD2105.2 is a data logger. It memorizes up to 34,000 pH or mV and temperature samples which can be transferred from the instrument connected to a PC via the RS232C serial port or USB 2.0 port. 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. Display, printing and, for the model HD2105.2, storing always include temperature, in °C or °F, and pH or mV.

The Max, Min and Avg function calculates 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 disabled.The instruments have IP66 protection degree
