Rugged, integral pH electrode in protective housing. Sealed protective cap can be filled with water to keep electrode activated and to prolong its life. This tester is ideal for swimming pools, fish farming, electroplating industry, printing, agriculture, waste water processing and many other applications where humidity and condensation would render litmus paper useless or ruin the circuitry of ordinary meters. The auto switch-off feature prolongs the life of the batteries, delivering up to 300 hours of use. The display indicates when a stable pH value has been reached, ensuring that only accurate readings are taken.
Calibration is automatic and can be performed easily, even by non-technical operators.
Simply press the 'ON' button for 3 seconds, and the display prompts the user to submerge the tester into pH 7 buffer. When that is completed, the meter is automatically calibrated and returns to operating mode. Microprocessor based with error and self-diagnostic messages. Last digit on display will flash until reading is stable. Automatic calibration - just press 'ON' button, dip in pH buffer and unit is calibrated.
