The Checker is one of the most popular pH meters in the world, with over 1 million units in use since its launch in 1991. It is a simple and easy-to-use instrument, ideal for students and researchers measuring pH. • Single-button operation • Replaceable pH electrode • pH accuracy of ±0.2 The HI98100 Checker Plus offers advanced features while maintaining the design and functionality of the original model. It allows for automatic calibration at 1 or 2 points, automatic recognition of buffer solutions, display of calibration labels, a stability indicator, a low battery indicator, and selectable automatic shut-off. Its pentagonal design with a 102 mm probe length and 8 mm diameter makes it ideal for checking pH in aquariums and other applications. **Economical:** The Checker is an affordable pH tester that offers a wide range of features at a competitive price. **LCD Display:** The enhanced display shows the reading, stability indicator, low battery indicator, and calibration labels. **Replaceable pH Electrode:** Supplied with the HI1271 pH electrode, featuring a tip diameter of 8 mm, ideal for use in test tubes or narrow containers. **Automatic Calibration:** Calibration is performed automatically at 1 or 2 points, with automatic recognition of buffer solutions. The values of the solutions used are displayed on the screen after calibration. **Stability Indicator:** A hourglass is shown on the screen until the reading stabilizes. After stabilization, the indicator disappears, allowing the reading to be recorded. **Automatic Shut-off:** The device can be set to automatically turn off after 8 minutes or 60 minutes of inactivity to save battery. The auto shut-off feature can be disabled. **Extended Battery Life:** The Checker provides a battery life of approximately 1000 hours. The low battery indicator appears when the power is nearly depleted.
