Where are Hanna Instruments made?
Hanna Instruments is headquartered in Woonsocket, Rhode Island and has manufacturing sites in Mauritius, Singapore, Hungary and Romania. All production facilities are ISO 9001 Certified.
How accurate are electronic pH testers?
Most manufacturers of pH electrodes build to a quality level that gives an accuracy of approximately 0.1 pH. If the pH sensor is properly maintained, calibrations done correctly, and stored according to manufacturer recommendations, then 0.1 is possible.
When should I replace my pH meter?
Most people get a good 12-18 months out of a pH probe before needing to replace it. Measuring pH is important. A pH probe is an essential tool in a wide variety of industries and applications.
What is the most accurate pH testing method?
pH meters
The most precise of the 3 test options, pH meters measure a solution’s pH by measuring the electrical potential difference between the pH electrode and a reference electrode.
Are pH meters accurate?
Accuracy of meters generally range from ±0.1 pH to ±0.001 pH. For instance, a pH meter with an accuracy of ±0.01 is a good choice for quality control or research environments, however, a pH meter with an accuracy of ±0.10 may be more affordable for a school laboratory and be adequate for their needs.
Can I use pH meter without calibration?
pH probes, or pH meters, are very useful tools in quickly identifying the pH of a sample. This statement often overlooks how to calibrate a pH meter, since a pH meter without calibration is practically useless.
How do I calibrate my pH meter at home?
Pour some pH 4.0 calibration solution into a small cup and insert the electrode. Once the meter is calibrated with the 4.0 solution, it will flash 7.0. Rinse the probe with distilled water, dry it and insert it into a cup of 7.0 calibration solution. Once it stops flashing, it is calibrated and ready for use.
Can you leave pH meter in water?
DO NOT soak or store any pH probes in purified water like distilled water, deionized water, or reverse osmosis water since it could cause damage to the pH electrode and the tester could give erratic readings. Rinsing the probes in purified water is a good practice. Just don’t store them in purified water.
Why buy a Hanna PH meter?

What does the Hanna Instruments Hi 98129 measure?
The Hanna Instruments HI 98129 is a multi-parameter tester that measures pH, electro-conductivity (EC), total dissolved solids (TDS), and temperature, and features automatic temperature compensation (ATC), an LCD screen, automatic shut-off, and a waterproof body that floats in water.
How does the Hi 98129 pH tester work?
The tester automatically compensates for the effects of temperature when taking pH and EC/TDS readings, so additional measurements and manual temperature entries are unnecessary. The HI 98129 meter has a replaceable pH electrode with an extendable cloth junction, and an EC/TDS graphite electrode that is resistant to salts and other corrosives.
How do I Know my pH meter is accurate?
Your edge pH meter will automatically recognize each digital electrode, providing sensor type, calibration data, and serial number. Trust your results. On-screen indicators track the condition of your electrode between calibrations so you can always be sure you’re getting accurate results.
