• • • • • • • • • • • • • 【NOTICE】:To perform a pH test, take a small sample of the food using clean utensils. This sample should represent the food being tested. After testing, discard the sample as it is not edible.
                        • 【RAINLEOTI Food pH Meter】:The digital pH meter provides highly accurate digital readings with a measurement range of 0.00 to 14.00 pH, a resolution of 0.01 pH, and an accuracy of ±0.1 pH. Featuring advanced chip technology and an Automatic Temperature Compensation (ATC) system, it ensures precise measurements across varying temperatures, with a clear LCD backlight for visibility in all lighting conditions. Whether you're testing liquid or solid foods, this meter offers fast, reliable results, making it an ideal tool for home and professional use.
                        • 【Perfect for Fermented Foods】:This pH meter is ideal for testing fermented foods like chili sauce, cheese, sushi rice, jam, and sourdough bread. Its unique spear-type probe with a glass bead sensor delivers accurate readings to monitor the fermentation process and ensure optimal conditions for your recipes.
                        • 【Versatile Testing for Solids&Liquids】:The RAINLEOTI pH Meter features a puncture electrode design, allowing you to test both solid and semi-solid samples (e.g., meat, cheese, fruit) as well as liquid solutions (e.g., water, salad dressing). With its 2-in-1 functionality, it is perfect for various applications such as home brewing, baking, and even soil testing for gardening projects.
                        • 【Easy Calibration】:To achieve optimal accuracy, perform a factory reset before starting the automatic calibration process. Additionally, calibrate the device using the included calibration powder or compatible solution (automatic calibration) before use. After calibration, there is no need to repeatedly calibrate with multiple solutions of different pH values—simply ensure the device is correctly calibrated to obtain consistent and precise results.
                        • 【User-Friendly Design】:With just three simple buttons—ON/OFF,TEMP/CAL,and HOLD—this device is easy to use,even for beginners. The ON/OFF button powers the device, the TEMP/CAL button switches between temperature units and pH calibration, and the **HOLD** button locks the reading for easy reference.
                        • 【Durable and Reliable】:Built for long-term use, the RAINLEOTI pH Meter is constructed from high-quality materials. The replaceable electrode ensures extended lifespan, and the device comes with a one-year warranty against non-human damage. Should you have any concerns, our customer service team is ready to assist.
                        • 【Important Handling Instructions】:Please handle the probe with care, as it is made of delicate glass. Avoid dropping, rough handling, or exposing the probe to overheated solutions, as this may damage the meter. Minor fluctuations in readings are normal when the probe encounters air, but avoid impacting or colliding with the electrode’s glass bulb, as this can cause cracks. If damaged, the electrode must be replaced to maintain accurate testing.
