Oakton 35614-80 pH 11 Economy Meter Kit Review
The Oakton 35614-80 pH 11 meter kit features a handheld meter that has push-button calibration with auto-scanning, and comes with an all-in-one pH/temperature probe, calibration pouches, storage bottles, and two electrode holders. A portable meter is commonly used to measure the pH, mV, and temperature of substance in water treatment and swimming pools in hydroponics, aquaculture, and educational applications.
This meter features a two-electrode bracket for one-handed use, and ATC for accurate readings, push-button capabilities with auto-scanning up to five points, and buffer recognition of National Institute of Standards and Technology (NIST) and USA standards. It has a large, digital LCD display to view pH, mV, and temperature, a hold function for reading and recording data, a ready indicator, and an auto-off function for automatic shut-off after a period of nonuse. The meter has the ability to recall up to 50 data sets, comes with an all-in-one pH/temperature probe (35811-71), and has a built-in electrode stand for benchtop use.
The 35614-80 pH 11 has an operating temperature of 0 to 50 degrees C (32 to 122 F) and buffer recognition standards USA 1.68, 4.01, 7.00, 10.01, 12.45; NIST 1.68, 4.01, 6.86, 9.18, 12.45. pH range -2.00 to 16.00, resolution 0.01, accuracy + or - 0.01. MV range -199.9 to +199.9, -1999 to + 1999, resolution 0.1, 1, accuracy + or - 0.2 + or - 2 mV beyond + or - 199.9. Temperature range -10.00 to 110.0 C, resolution 0.1 degree C, accuracy + or - 0.5 degree C. Its dimensions are 7.38 (l) x 3.5 (w) x 1.75 (d) inches and it weighs 1.3 lb. The meter works with four 1.5-V AAA batteries (included) or AC adapter (not included) for up to 700 hours of continuous use.
pH testers measure the acidity or alkalinity of a substance. Ion Selective Electrodes (ISEs) respond selectively to ions in the presence of other ions, and are commonly used for water-testing, and to analyze biological samples in hydroponics, aquaculture, and agriculture.
Oakton Instruments manufactures an array of scientific instruments for research, industrial, and educational uses. Since 1991, Oakton has distributed a wide variety of instruments such as meters, electrodes, and transmitters. Oakton is based in Vernon Hills, IL, and has facilities in Europe, Asia, and China.

Hanna Instruments HI 2211 Benchtop pH/mV and Temperature Meter Review
The HI 2211 is a micro-processor based pH, mV, ion concentration and temperature bench meter with a glass-body, single-junction, refillable pH electrode, and a temperature probe.
The meter features a large LCD screen, automatic temperature compensation (ATC) with the temperature probe (manual with the pH electrode), and a stability indicator to prevent inaccurate readings. Calibration is automatic at one or two points, with five memorized buffers (pH 4.01, 6.86, 7.01, 9.18, 10.01) and an on-screen step-by-step calibration tutorial.
pH range is -2.00 to 16.00 (+ or - 0.01pH) with a resolution of 0.01 pH. Temperature range is – 9.9 to 120 degrees C + or - 0.5 degrees C (up to 100 degrees C), + or -1 degrees C (outside) with a resolution of 0.1 degrees C. ORP range is + or - 399.9 mV; + or - 2000 mV with accuracy + or - 0.2 mV (+ or - 399.9 mV); + or - 1 mV (+ or - 2000 mV), and resolution 0.1 mV; 1 mV. Power supply is a 12 VDC adapter and input impedance is 1E12 Ohm. Dimensions are 240 x 182 x 74 mm (9.4 x 7.1 x 2.9") with weight 1.1 Kg (2.5 lb); kit with holder 2.5 Kg (5.5 lb).
pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.
Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries.

Oakton pH Tester pHTestr 20 Review
The Oakton 35634-20 pH Testr 20 is a handheld, waterproof and dustproof meter that floats, if dropped in liquid, and features a replaceable double-junction electrode within its reusable tester body. A portable meter is commonly used to measure the pH of substance such as food, beer, or wine, and is also used to test cleaning water, rinse water, and wastewater in chemical, industrial, and food applications. This microprocessor-based meter has Automatic Temperature Compensation (ATC) for accurate readings in fluctuating temperatures, and three-point, push-button calibration with auto-buffer recognition of US and National Institute of Standards and Technology (NIST) standards for a wide range of results. The meter’s waterproof and dustproof housing has Ingress Protection (IP) 67-rating for protection against solid objects or liquids. It has a large, upright, dual-line LCD screen for ease of viewing, error messages, a hold function which freezes readings for recording, and an auto shut-off that turns the meter off after 8.5 minutes of nonuse to extend the life of the batteries. A protective cap reduces contamination, and a double silicone O-ring eases electrode module replacement.
The 35634-20 tester has ATC from 0 to 50 degrees C (32 to 122 degrees F), and operating temperature of 0 to 50 degrees C (32 to 122 degrees F). pH range -1.00 to 15.00, resolution 0.01, accuracy + or - 0.01, calibration up to three points with US or NIST buffers at 4.0, 6.86, 7.0, 9.18, 10.0. It can be used with Tris buffers. Its dimensions are 6.5 (h) x 1.5 (w) inches (16.8 x 3.8 cm), and it weighs 3.25 ounces. The tester works with four 1.5 V alkaline batteries (not included) for up to 500 hours of continuous use (Eveready A76 or LR44 equivalent replacements).
pH testers measure the acidity or alkalinity of a substance. They are commonly used for water testing, and for biological sample analysis in hydroponics, aquaculture, and agriculture.
