The Apera Instruments Premium-Series PH60S Food pH Pocket Tester Kit is a versatile and accurate tool, ideal for measuring the pH of a variety of foods such as cheese, sushi rice, meat, and fruits. Its key strength is the Swiss spear sensor, providing high accuracy (±0.01 pH) and a broad range (-2.00 to 16.00 pH), which ensures reliable results for both solid and semi-solid food items. The long-life reference system and replaceable sensor add to its durability, making it a long-term investment for users who frequently need pH testing.

The tester's ease of use is enhanced by features such as automatic calibration, temperature compensation, and a large clear LCD with three backlit colors for different modes, which simplifies readings and indicates when results are stable and calibrations are complete. Additionally, a high/low value alarm function with a red backlight provides instant alerts for out-of-range results, adding an extra layer of usability and safety.

The kit is comprehensive, including calibration solutions, storage solutions, and even a portable carrying case, making it handy for both professional and home use. The product dimensions are compact (7 x 1.6 x 1.6 inches; 5.1 ounces), making it easy to handle and carry. While it is made in China, the quality and performance are on par with industry standards. This pH tester is particularly beneficial for culinary professionals, food safety inspectors, and home chefs who require precise pH measurements for food quality control.
