Thanks to an internal pressure sensor, the instrument performs the automatic compensation of the barometric pressure.
\nThe permeability of the oxygen probe membrane and the salinity of the liquid under test are also compensated, automatically. The fast, calibration function of the dissolved oxygen probe ensures the accuracy of the measurements made over time.<\/p>\n
The dissolved oxygen and temperature probe, equipped with an automatic recognition module, stores factory calibration data internally. The HD2109.2 instrument is a datalogger, stores up to 18,000 samples of dissolved oxygen concentration,saturation index, barometric pressure and temperature that can be transferred to a PC connected to the instrument via the multi-standard RS232C and USB 2.0 serial port.<\/p>\n
From the menu you can configure the storage interval, printing, baud rate. The HD 2109.1 is equipped with an RS232C serial port and can transfer, in real time, acquired measurements to a PC or portable printer. The Max, Min and Avg function calculates the maximum, minimum and average values.<\/p>\n
Other functions include REL relative measurement, Auto-HOLD function, and excludable automatic shutdown.
\nThe instrument has IP67 degree of protection.<\/p>\n
