Hanna HI981039 Chocolate Checker pH Tester

Hanna HI981039 Chocolate pH Tester

The Hanna HI981039 Chocolate Checker pH Tester is a portable, waterproof digital meter specifically engineered for measuring pH directly in chocolate and chocolate-based mixtures. With a conical-tip electrode and replaceable bridge electrolyte, this tester is optimized for semi-solid, rich, and viscous food samples, ensuring accurate and reliable pH monitoring throughout chocolate production.

Features

• Purpose-Built for Chocolate Applications
  Featuring a conical glass tip and open junction, this tester is designed to penetrate thick or semi-solid chocolate blends. As a result, users can measure pH in raw cocoa, melted chocolate, ganache, or emulsified compounds with ease and precision.

• Exceptional Accuracy and Resolution
  With 0.01 pH resolution and ±0.05 pH accuracy, the HI981039 supports detailed quality assessments during fermentation, tempering, or product development. Therefore, chocolatiers and QA teams can rely on it for consistent and reproducible results.

• Automatic Temperature Compensation (ATC)
  The built-in temperature sensor automatically adjusts pH readings between 0 and 50°C, ensuring measurement integrity even in warm melted chocolate or cooled solidified forms. Moreover, ATC enhances accuracy when conditions fluctuate during processing.

• Easy Calibration and Maintenance
  The tester supports one or two-point automatic calibration using standard buffers (e.g., pH 4.01, 7.01, or 10.01). Furthermore, its replaceable bridge electrolyte ensures extended lifespan and easier maintenance—ideal for high-frequency testing environments.

• Compact, Waterproof, and Hygienic Design
  Built to IP67 waterproof standards, the tester is ideal for the demands of a food lab or production floor. In addition, its compact form factor and food-grade materials allow for quick cleaning and portability.

• Efficient Battery with Auto Shut-Off
  Powered by a CR2032 lithium-ion battery, the unit provides up to 800 hours of continuous use. Additionally, the smart auto-off feature (selectable between 8 minutes, 60 minutes, or disabled) preserves energy between uses.
