Apera Instruments AI311 Premium Series PH60 Waterproof pH Pocket Tester Kit, Replaceable Probe, ±0.01 pH Accuracy, Lcd display

Apera Instruments PH60 Pocket pH Tester is designed for reliable and easy pH measurement for general water solutions, such as in hydroponics, horticulture, aquaculture, pools& spas, water treatment, cooling towers, environmental monitoring, beverage making, education, etc. The meter comes with a replaceable pH probe (PH60-E) for general water solutions pH test. The meter is also compatible with 3 other types of pH electrodes and an ORP probe (sold separately) for different applications such as solid samples and surface tests. NOTE: Add a few drops of 3M KCL liquid (included in the kit) to their test sample (usually low ion-strength liquid like distilled water or RO water), which will significantly help accelerate the stabilization without affecting the pH reading.

• NOTE: A few drops of water are added to the electrode cap before the product leaves the factory. This is to maintain the sensitivity of the electrode. Therefore, when you use it for the first time, it is normal to find water droplets in the electrode cap
• Accuracy: 0.01 pH; range: -2.00 to 16.00 pH, 32 to 122˚F (0 to 50˚C); Auto. Power-Off: 8 minutes without operation
• Easy 1-3 points auto. calibration, recognizes 5 types of solutions (1.68, 4.00, 7.00, 10.01, 12.46); Auto Temp. Compensation (ATC) ensures accuracy in various temperatures (32-122˚F)
• High quality replaceable glass pH probe, suitable for regular water solutions e.g. pools&spas, hydroponics, environmental monitoring, cooling towers, beverage, etc.
• Large LCD with 3 backlit colors (indicating different modes), dual display of temp./pH, and reminders of completed calibrations and stable readings
• The smiley icon indicates stable readings so you won't have to guess when is the right time to record the measurements
• COMPLETE KIT with READY-TO-USE calibration solutions, calibration bottles, storage solutions, AAA batteries, and a lanyard all in a rugged portable case
