Hanna Instruments HI-98165 is a portable pH and temperature meter designed for cheese products. The HI-98165 is supplied with an FC2423 electrode, specifically made to measure pH in cheese. This electrode has a conic tip shape for easy penetration and is 5mm in diameter so it doesn't leave a large hole. The electrode connects with the meter via a waterproof DIN connector. The user can test throughout the production process using the conical sensing tip paired with the robust sheath.
The Hanna HI-98165 unique CAL Check™ alerts the user to potential problems in the calibration process. Food processors will find this very important as the probe is likely coated with the solids found in the food sample being measured. Once the probe is coated, it could lead to errors in the pH measurement. Another of the HI-98165 features is AutoHold. Once enabled it will warn the user when a reading is not within the range of calibrated pH values. The Log-on-demand mode lets the user save up to 200 samples which can then be recalled or transferred to a PC.
