The product is mainly used for measuring solid orsemi-solid dielectric electrodes containing water. When inserting the electrode, please pay attention to using evenforce to prevents electrode damage. If the tested medium is relatively solid (such as meat and fruit), a small hole should be pierced first, and then the electrode should be inserted. When testing food (such as sushi. cheese, meat, fruit, etc.), samples should be used only for testing, and the test sample should not be edible, When testing soil, be careful not to directly insert it into too hard soil, as it may damage the electrode. Features: This portable handheld penetrating pH meter is suitable for soil and food processing use, such as fruit, vegetables, jam, paste, bread, gel, some kinds of meat, and more kinds of semisolid food. It can also measure the temperature of solution, measuring temperature ranges from 0 celsius to 50 celsius , celsius Fahrenheit unit switchable for meeting various needs. Digital LCD screen with backlight, clear at a glance, easy to read even in dark environments. Powered by 2 AAA batteries (not included), auto shutdown to save energy. Alarm Function: When the pH is below 3.5 or above 12.5, the red backlight lights up. When the ambient temperature is below 0 celsius , the LCD displays LO, when above 50 celsius , it displays HI. High precision detachable probes are easy to use and replace; 0-50 celsius automatic temperature compensation ensures accurate results; data hold function for convenient reading.
