• Measures pH, conductivity, salinity, TDS and temperature
• Replaceable pH electrode and conductivity sensor extend tester life
• Fits in your pocket!

The USABlueBook PlantPro FastPCST tester combines the features of a pH, conductivity, salinity, TDS and temperature meter into one pocket-sized tester. Meter displays measured value along with temperature—simply press a button to toggle between the different parameters.

The tester features auto buffer recognition for quick, easy calibration. Manual or automatic temperature compensation (ATC) provides accurate readings, even in varying conditions. The easily replaced single-junction pH/conductivity electrode saves you money over time, and the IP67-rated waterproof housing floats if dropped in water. Additional features include Hold, self-diagnostic messages, battery life indicator and automatic power-off after 8.5 minutes of non-use.

Includes: four 1.5V button batteries, lanyard, manual and transparent case. 1-year meter warranty; 6-month electrode warranty.
