It obtains a continuous high accuracy using fresh reference solution and has fast and easy steps to refill your electrode. This meter eliminates the concern of the electrode shelf life. The 1, 2 or 3 point calibration automatically recognizes the buffer solutions. The user must order the pH buffers separately.

Review: Love my Extech! - I bought this to use for cheese making, and it has fulfilled all my expectations, including the ability to check the pH of the cheese itself, rather than just the whey as most other meters are limited to. I can only hope that it will prove as reliable in the long run as it has in the short run, providing reliable information to 2 decimal points, which comes in very handy. I love it and would recommend it to anyone needing such accuracy and reliability. Review: Accurate and easy to use - Use for work and it works great and accurate. ## Features - Refillable pH electrode is easily serviced - Analog bargraph displayed on LCD - shows trends in acidity or alkalinity - Waterproof to IP57 standard - 1, 2 or 3 point calibration automatically recognizes buffer solutions - Flat Surface Electrode measures pH in liquids, semi-solids, and solids ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004WN9QUG | | Batteries | 4 Lithium Metal batteries required.

How can we do it once purchased?** A: I am not sure if you can use this to test the pH if a person. Perhaps by putting it in sweaty skin. You should call manufacturer to see if they can answer your question. **Q: can i use this meter for cheesemaking?** A: Don't see why notCheesemaking websites list similar ones, maybe less precise than this but same technology **Q: Can I use for stiff dough?** A: Yes you can. This can read liquids and solids. I use mine to measure the ph of cheese curds and whey. **Q: I have a very similar meter but it is "ph110" instead of "ph100." will this "ph105" sensor work with the "ph110?"** A: Yes the PH105 is the replacement pH electrode for both the PH100 and PH110. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love my Extech! *by B***7 on January 14, 2013* I bought this to use for cheese making, and it has fulfilled all my expectations, including the ability to check the pH of the cheese itself, rather than just the whey as most other meters are limited to.

Works well otherwise. Sucks that it's too much trouble to replace it - not worth the time of packaging & shipping out , then waiting on a new one. Tired of getting Amazon stuff that was broken BEFORE it was packaged and sent. ## Frequently Bought Together - Extech PH110 Waterproof ExStik pH Meter - Apera Instruments AI1113 pH Calibration Buffer Solution Kit (7.00, 4.00), 8 oz.
