Featuring automatic temperature compensation, dual-line LCD display, and smart automatic calibration, it delivers precise readings with ±0.05 pH accuracy. Its waterproof, dustproof housing floats for durability in challenging environments, while a replaceable electrode cartridge extends meter life. Powered by four AA batteries, it offers up to 300 hours of continuous use with battery status alerts and auto-shutdown to conserve power. ## Description The Hanna Instruments HI 98128 is a compact pH tester used in laboratory and industrial applications, and has Automatic Temperature Compensation (ATC), automatic calibration, a dual-line LCD screen, a replaceable electrode cartridge, and a housing that floats. A pH meter is commonly used to measure the pH of substance such as water, food, beer, or wine in laboratory, industrial, and food applications. The dual-line LCD screen simultaneously shows the current measurement and the current temperature, and a hold function freezes readings for recording. The meter has automatic calibration at one or two points with two sets of standard buffers (pH 4.01/7.01/10.01 or pH 4.01/6.86/9.18). The meter has a water-resistant housing, a tactile grip casing, and floats. A battery error prevention system alerts when battery power is low and displays battery percentage on startup. Four 1.5V AA batteries provide approximately 300 hours of continuous use. The meter switches off after eight minutes of inactivity to save battery life. The meter also comes with a HI 73127 pH electrode, an electrode removal tool, and instructions.

A pH meter, also called a sensor or tester, is a device used to measure the acidity or alkalinity of a substance. A pH meter has either a portable or a benchtop body. Many portable meters are handheld devices. Some testers have an internal sensor, and may have a tip and body that fit inside of a container for measurement. A meter is commonly used in many different environments from laboratories to field research and manufacturing facilities. Researchers, manufacturers, and hobbyists use a pH meter in aquaculture, agricultural, wine-making, and water-testing, and for scientific applications. Some pH meters may measure additional parameters such as dissolved oxygen (DO), conductivity (also called electro-conductivity or EC), temperature, total dissolved solids (TDS), salinity, resistivity, or oxygen reduction potential (ORP)/mV.Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) standard 9001.What’s in the Box?HI 98128 pH testerHI 73127 pH electrodeHI 73128 electrode removal toolAA batteries (4)Instructions Review: Hanna is the best. - Taking my local extension Master Gardner program we used these to do soil tests. Since then I have started my own lawn care company and I tried cheaper ones with very inconsistent results. The Hanna works very well, plus they have headquarters only a few miles from me! Review: Great household pH meter - I'm a homebrewer and I got one of these for measuring the pH of my grape must. I'm also a cook and a physicist and I like being able to measure the pH of lots of things. This is a nice balance between price and accuracy. This is probably as accurate as you would need for any household application. You need to have a buffer solution to store it in and you should have two solutions for calibrating. It's not trivial to use properly (you should read the manual) but it's not difficult either. ## Features - Compact pH and temperature tester used in laboratory and industrial applications - Automatic Temperature Compensation (ATC) for accurate pH readings in fluctuating temperatures and automatic calibration at one or two points to help prevent calibration errors - Dual-level LCD screen simultaneously shows the current measurement and the current temperature - Replaceable electrode cartridge to extend meter life - Waterproof, dustproof housing allows the tester to float ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.2 out of 5 stars 132 Reviews | ## Images ![Hanna Instruments HI98128 pHep 5pH/Temperature Tester, 6-25/64" Length x 1-19/32" Width x 1" Height - Image 1](https://m.media-amazon.com/images/I/710RFGLkVaL.jpg) ## Questions & Answers **Q: From all of the reviews, it seems most of these units dont last past 90 days. Can someone with expertise address this issue?** A: pH meters in general do not last long. Sometimes a new probe will fix the problem, but not often. I have never had a Hanna pH tester last more than 90 days if it even gets that far. Support is poor. **Q: Does this meter have an electrode that can be used to test curd in cheese making?** A: The probe is recessed in the unit, so it would be difficult to test curd. **Q: Where can I find the replacement electrode** A: Replacement electrodes are avail at www.hannainst.com. You will need the tool supplied with the instrument to make the change! **Q: Can use for solvent base paint** A: checked with our Tech Dept. and they said the HI 9812X series of pH testers would not work for the testing of pH in solvent based paints.Sincerely, ## Customer Reviews ### ⭐⭐⭐⭐⭐ Hanna is the best. *by K***S on February 17, 2020* Taking my local extension Master Gardner program we used these to do soil tests.

I followed all the storage and usage instructions, and every day the pH was more than 2 points out of calibration. The last time I turned it on it was stuck at 16 pH and 221 degrees temp and the cleaning solution, ice water, etc wouldn't change the reading. THe battery then died and now with new batteries it won't turn on at all. worst pH meter ever - don't waste your money ## Frequently Bought Together - Hanna Instruments HI98128 pHep 5pH/Temperature Tester, 6-25/64" Length x 1-19/32" Width x 1" Height - Hanna Instruments HI70300L pH/ORP Electrode Storage Solution, 500mL (16.9oz) Bottle - Hanna Instruments HI73127 Polypropylene Spare Electrode with Pin Connection, 0 to 14 pH --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/659118569-hanna-instruments-hi98128-phep-5ph-temperature-tester-6-25-64](https://www.desertcart.hr/products/659118569-hanna-instruments-hi98128-phep-5ph-temperature-tester-6-25-64) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-24*
