The HI2550 is a rugged and highly accurate multiparameter benchtop meter that measures pH/ORP, EC/TDS/Salinity, and temperature with a clear LCD display, data logging capability, and USB port for computer connectivity.
The HI2550 is a dual channel meter that allows for measurement of pH and ORPE on one channel and EC, TDS, and salinity, on the other. Readings for pH and EC can be manually or automatically compensated for temperature variations with the separate HI7662 temperature probe or from the built-in temperature sensor of the conductivity probe on channel two.
As a pH meter, the HI2550 can be calibrated up to five points with a choice of seven standard buffers or two custom buffers. As an EC/TDS/Salinity meter, the HI2550 can be calibrated at one point for offset and at one point for slope with a choice of six conductivity standards. The % NaCl is calibrated to a single point at 100% with the optional HI7037 salinity standard. The calibration data including date, time, standards used, offset, slope, cell constant, and cell factor can be accessed at any time by pressing the dedicated GLP button.
