combined portable measuring device | HD 2156
pH, ORP, conductivity, TDS, temperature
The models HD2156.1 and HD2156.2 are portable instruments with a large LCD display. They measure pH, mV, redox potential (ORP), conductivity, liquid resistivity, total dissolved solids (TDS) and salinity using combined 4-ring and 2-ring conductivity / temperature probes. Temperature only is measured by Pt100 or Pt1000 immersion, penetration, contact or air probes.
The pH electrode calibration, as well as manual, can be carried out on one, two or three points and the calibration sequence can be chosen from a list of 13 buffers.
The calibration of the conductivity probe can be performed automatically in one or more of the 147 μS/cm, 1,413 μS/cm, 12,880 μS/cm or 111,800 μS/cm solutions.
The HD2156.2 instrument has a integrated datalogger. It stores up to 20,000 sets of three measurements composed of pH or mV, conductivity or resistivity or TDS or salinity and temperature: these data can be transferred to a PC from the instrument connected via the RS232C or USB 2.0 serial ports. The storing interval, printing, and baud rate can be configured via the menu.
Both models 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 Auto-HOLD function and the automatic turning off which can also be excluded.
Probes and cables are NOT included in the scope of supply. Please order separately!
