Featuring auto temperature compensation, easy multi-point calibration, and a replaceable glass probe, it’s designed for professionals managing water quality in hydroponics, pools, beverages, and environmental monitoring. The kit includes all essentials in a rugged case, ensuring you’re ready to measure with confidence anywhere. ## Description 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. ## Features - 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01ENFOIQE | | Batteries | 4 AAA batteries required.

Close on the probe cap tightly with the O-ring. 7.3 If you find white crystals inside or outside the probe cap, it is perfectly normal. It is the 3M KCL soaking solution that crystalizes over time by its nature. Just rinse them off and add in new soaking solution. This chemical is not poisonous nor dangerous, and the probe’s performance will not be affected at all. 7.4 NEVER store the probe in pure water like tap, RO, distilled, or deionized water as they could damage the pH probe. Pure water is only for rinsing the probe. **Q: Would this work for chemistry experiments (done as part of a homeschool chemistry course)?** A: Yes, but advanced warning, we recommend keeping the ph measure above ph of 2 and below a ph of 12 as ph measures beyond those points will shorten the life of the sensor and is considered improper use and voids the warranty. It may be wise to check in advance if the chemistry course will have the student delving into substances more acidic than lemon juice like HCL, or more alkaline than hand soap. Be sure to have distilled water to rinse all substances away from the probe when testing. **Q: Looked up the replacement probes. Freaking 35-50 bucks on average. Could just buy a whole new pen for that much? Any cheap replacment probes?** A: Just replaced my probe on my PH60 after 2.5 years use. Got it in two days, for $28. **Q: Does this check PPM ?** A: No, that would be our EC60 and PC60 that will do PPM under the measurement for Total Dissolved Solids (TDS). PH60 does only PH and mV for an ORP probe sold separately. ## Frequently Bought Together - Apera Instruments AI311 Premium Series PH60 Waterproof pH Pocket Tester Kit, Replaceable Probe, ±0.01 pH Accuracy, Lcd display - Apera Instruments AI1113 pH Calibration Buffer Solution Kit (7.00, 4.00), 8 oz.
