Un ph-mètre très précis, facile à calibrer, mesure assez rapide pour un usage non industriel.

Meter just arrived and it is missing the pH/temp probe.

I am coming from a PH pen that was about $75. No comparison, this reads much faster no more hunting in stable water. This is also more accurate, so you can do the rounding instead of the meter doing it. I didn't want to have to buy a new meter, because mine was only about a year old, but this is a huge upgrade so I'm glad I did.

As someone who writes Standard Operating Procedures for a living, I always appreciate a well written instruction manual that is easy to follow.My first attempt at a three point calibration was successful with maybe 0.3 uncertainty max, keep in mind your buffer solutions have labels that show their variance in temperature and I live in Texas so this is still decent for it being hot the day it arrived. Second attempt at a three point calibration went perfectly, on the dot for low, middle, and High! Some advice would be to make sure whatever solution or slurry you are measuring it as close to the temperature of your buffer solutions.

Purchased to use in small-scale lab for checking pH of recycled antifreeze. Needed something dependable, accurate, and user-friendly. The pH850 fits this to a tee. for the price you get everything you need to calibrate and test. The stirrer plate is sometimes erratic but this can be eliminated by using the right size stir bar. Calibration is easy to perform and included are the 3 main buffers, 4, 7, and 10. The sticking point here is they do not reference a lot # but they work and can be checked against a certified standard. I contacted their technical department to discuss (great customer service) and found that these are the buffers included with probe but if you ordered the larger sizes a lot number is included. The buffer bottles are the right size to use for calibration without having to pour into different containers. When they become "used" just empty, rinse, and refill. Unit seems very rugged. One concern is the protective cap around electrode bulb seems somewhat flimsy and can crack easily, just exercise care. overall a good unit for the money. Actually would give 4 1/2 stars.

The PH850 is great for brewing beer! It has the temperature range to just drop the probe right in the mash and even in the boil. It also seems to be far more accurate than those $30 units. I could never get two readings in a row to be in the same ballpark with the cheap ones, but this one consistently reads the same every time with the same measurement sample.

We use this pH meter to assess the acidity of our newly made wines. The accuracy of the acid measurement provided by this pH meter enables us to proceed thru subsequent steps in the wine making process.

I've been holding off on purchasing a decent pH meter for over a year and probably did not need one that matches the quality and accuracy of the one that is included in the Apera Instruments Value Series PH850 Portable Handheld pH Meter Kit. Nevertheless, I'm very please with my purchase.The ph meter and probe appear to be well built and durable, the 3-point calibration process is very simple to follow and can be accomplished quickly, the carrying case is convenient for storage and portability of the meter, probe, buffer solutions, etc., and the instruction manual is relatively easy to follow. I feel confident I completely understand how to operate the meter and select my preferred operating parameters.I'm happy with my purchase.Thanks APERA!

Absolutely love this PH850!! Super accurate and fast, a real pleasure to use in hard to reach areas. I have owned the PH20 and PH60 also....I once lost the PH60, found it in a reservoir when I emptied it a couple weeks later...looks bad but worked perfectly! I have had nothing but reliable, accurate readings from all of my Apera meters. I recommend this meter and their other meters as well. The quality to price just isn’t being beat.
