The HI3512 is a highly accurate multiparameter benchtop meter that measures pH/ORP/ISE, EC/TDS/Resistivity/Salinity, and temperature with a clear and informative LCD display, data logging capability, and USB port for computer connectivity.
The HI3512 is a dual channel meter that allows for measurement of pH, ORP, and ISE on one channel and EC, TDS, resistivity and salinity, on the other. Readings for pH and EC can be manually or automatically compensated for temperature variations with the separate HI7662-T temperature probe or from the built-in temperature sensor of the conductivity probe on channel two.
As a pH meter the HI3512 can be calibrated up to five points with a choice of seven standard buffers or two custom buffers. For use as an ISE meter, a five-point calibration with six standard buffers can be performed. As an EC/TDS/Resistivity meter the HI3512 can be calibrated up to two points with a choice of seven conductivity standards. The % NaCl is calibrated to a single point at 100% with the optional HI7037 salinity standard. All GLP data regarding pH, relative mV, ISE, EC, or salinity calibration is stored for the user to review when necessary.
