Hanna HI98103 Checker® pH Tester – Accurate, Affordable, and Easy to Use
The Hanna HI98103 Checker® pH Tester is a compact, user-friendly digital pH meter that offers accurate results at an unbeatable price. Designed for everyday testing, this meter is ideal for aquariums, hydroponics, environmental fieldwork, and classroom labs. Whether you’re a hobbyist or a professional, this pH tester makes measuring pH simple, fast, and reliable.
Simple to Use, Packed with Features
This latest version of the original Checker® includes a variety of improvements. First, it features automatic calibration to one or two points, eliminating the need for manual adjustments. Additionally, it automatically recognizes calibration buffers and displays buffer tags after calibration. You’ll also appreciate the stability indicator, which lets you know when your reading is steady and ready to record.
The large, easy-to-read LCD screen clearly displays your pH readings along with a low battery warning, so you’re never caught off guard. Furthermore, you can choose to have the device automatically shut off after 8 or 60 minutes, helping to conserve battery life. If preferred, this feature can also be turned off.
Slim, Compact, and Versatile
The Checker’s classic pentagon design remains, now paired with a slim, 103 mm-long probe that tapers to just 8 mm in diameter. This narrow design makes it perfect for small containers like test tubes, vials, and other tight spaces. It’s lightweight and portable, which means you can take it anywhere with ease.
Replaceable Electrode = Long-Term Value
One of the biggest advantages of the HI98103 is its replaceable HI1271 pH electrode. Over time, all pH electrodes wear out—but instead of buying a whole new meter, you can simply replace the electrode for just $15. This not only saves money, but it also extends the life of your device for years.
