Oxymeters-Thermometer, for dissolved oxygen measurement, saturation index and temperature.
The HD 2109.1 is a portable instrument with a large LCD display.
It measures the dissolved oxygen concentration in liquids (in mg / l), the saturation index (in%).
Thanks to an internal pressure sensor, the instrument performs the automatic compensation of the barometric pressure.
It offsets, in an automatic way, the permeability of the membrane of the oxygen probe and the salinity of the liquid under examination. The calibration function, fast, the dissolved oxygen probe guarantees lasting correctness of the performed measurements.
The probe of dissolved oxygen and temperature, equipped with an automatic recognition module, stores in its interior the factory calibration data. The HD2109.2 is a datalogger, it 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 serial port and USB 2.0 .
From the menu you can configure the storage interval, printing, and baud rate. The HD 2109.1 model is equipped with an RS232C serial port and can transfer in real time, the acquired measurements to a PC or to a portable printer. The Max, Min and Avg calculate the maximum, minimum and average.
Other functions include: the relative measurement REL, the Auto-HOLD function, and the automatic turning off.
The instrument has IP67 protection.
