Apera Instruments AI311 Premium Series PH60 Waterproof pH Pocket Tester Kit & LLC-AI1109 8oz. pH Calibration Buffer Solution Kit

Apera Instruments AI311 Premium Series PH60 Waterproof pH Pocket Tester Kit, Replaceable Probe, ±0.01 pH AccuracyApera 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.Apera Instruments, LLC-AI1109 8oz. pH Calibration Buffer Solution Kit (pH 4.00, 7.00 & 10.01), plus 4oz 3M KCL Storage Solution for pH/ORP ElectrodesApera Instruments pH Calibration Buffer Solution Kit (pH 4.00, 7.00 & 10.01, 8 oz. each), plus 4 oz. 3M KCL Soaking Storage Solution. Apera pH calibration buffers are produced in an ISO 9001:2015 facility with ISO 17025:2017 accreditation using high-purity reagents, deionized water and certified analytical balances in a temperature controlled environment. Reported values are accurate to +/- 0.01 pH at 25°C and are traceable to NIST Standard Reference Materials (SRMs). MSDS documents are downloadable. Certificate of analysis can be achieved by request. All pH buffers have a 2-year expiration from manufacture for an unopened bottle.
