【Become a Hot Sauce Maestro with a pH Food Tester 】The hot sauce pH level is important. A good pH level for the sauce is 3.4 and can be tested accurately with a food pH meter. The lower pH level of hot sauce preserves the hot sauce and allows for a longer shelf life. The accuracy of pH testing strips can't provide the precision necessary for hot sauce making. Say goodbye to guesswork, with the proper GIDIGI pH tester, you can master the art of creating perfectly balanced hot sauces.
【Food & Dairy pH Meter】Designed to bring simplicity to pH testing of food and dairy products. The specialized probe features a PVDF body, conical tip, and open junction making it ideal for direct measurement of semi-solid foods.The open junction design reduces clogging from suspended solids and proteins found in food and dairy products for a more stable pH measurement.The spear tip design allows for penetration into solids, semi solids, and emulsions for the direct measurement of pH .
