HD2109.1 Dissolved Oxygen Meter

Model  Description 
HD2109.1  HD2109.1 Dissolved Oxygen meter. Thermometer
HD2109.2  HD2109.2 Dissolved Oxygen Meter. Thermometer Data logger

The dissolved Oxygen and temperature probes are fitted with an automatic detection module, with the factory calibration settings already being memorized inside. The HD2109.2 is a datalogger.
It memorizes up to 18,000 dissolved Oxygen concentration, saturation index measurements, barometric pressure and temperature samples which can be transferred from the instrument connected to a PC 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 HD2109.1 and HD2109.2 dissolved oxygen meters are fitted with an RS232C serial port and can transfer the acquired measurements to a PC or to a portable printer in real time. 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 which can also be disabled.
