The Laqua PC210 is a high-quality 2-channel measuring instrument for pH value, mV (ORP), EC value (conductivity), TDS, salinity and resistivity with integrated data memory. The Laqua PC220 also features GLP compliance with real-time clock and date & time stamp, twice the internal memory and the ability to exchange data with the computer. Both instruments offer numerous adjustment and diagnostic functions, and it is possible to measure simultaneously with both connected probes, both measured variables are shown simultaneously on the display. The instrument is particularly robust (IP67) and ideal for use even under the toughest conditions. Made in Japan - highest reliability and quality.


LAQUA PC instrument, pH electrode for liquids, EC sensor for liquids, calibration standards, batteries, electrode adapter in carrying case.

A pH piercing electrode for direct measurement in soil and substrates is also available as an option!
