The portable instrument HD2156.2, with a large LCD display, measures the pH, the mV, the oxidation reduction potential (ORP),conductivity, resistivity in liquids, total dissolved solids (TDS) and salinity with combined conductivity probesand 2- and 4-ring temperature.
It also measures the temperature only with immersion, penetration, contact or air probes and Pt100 sensoror Pt1000.
The HD2156.2 instrument is a data logger that stores up to 20000 sets of data consisting of pH or mV, conductivity or resistivity or TDS or salinity and temperature: these data can be transferred to a PC connected to the instrument via the RS232C and USB 2.0 serial ports.
From the menu it is possible to configure the storage interval, printing, baud rate.
The 2156.2 model is equipped with an RS232C serial port and can transfer the acquired measurements in real time to a PC or portable printer.
The functions of the instrument are:
• Max, Min, Avg function calculates the maximum, minimum and average values;
• Auto-HOLD function;
• automatic shutdown which can be disabled.
