I don’t have to dilute my lotions and creams, cuts the time it takes to take a pH reading to less than half. Definitely a winner! I was worried that it would not work because the electrode storage solution had dried up upon arrival but it works great. Easy to calibrate too.

read anything... badly! lol You can add 1, 2 or 3 air pump in the same bucket, always the same reading. You take a measurement of tap water, back to the original and have a different reading...I guess the more accurate one worth it even if they are costly.

I do not recommend this ph meter. I attempted to use it and kept getting an error code that says "renew". After some research, I discovered the module is faulty (apparently a very common issue) and would cost $80 for a replacement part. Unfortunately I missed the 30 day deadline to return this item by the time I sourced ph calibration liquid because this device does not come with any. Very disappointed.

Easy to use. Read up on optical disolved oxygen sensors if u have never used one before

We've been using this pH meter in our Lab/Manufacturing setting for just over 1 year. We've had to replace it twice (which was an ok process) but it has now been confirmed by lab staff that the pH readings were inaccurate! Would not recommend that you buy this one.

We have several of these units and are finding quite a similar trend in their flawed design. They are not waterproof to their claimed IP57 standard. Water penetrates the probe and corrodes the circuit board inside. Thus, the entire meter has to be disposed of.

just the job we use a few of these and always does what it is supposed to do ie tells us the PH of the water leaving the factory

The second time we attempted to use the Extech "waterproof" DO Meter we found it totally dead. When we removed the cap, the entire inside of the meter was wet with water an battery acids. Either outside water had entered the meter from somewhere or the fluid around the probe found its way inside the meter. Either way this was not only a useless purchase but it's failure has possible compromised a study. Extech will not be on anybody's shopping list around here any time soon!

Avoid buying these or using this manufacturer.I was hoping to use the device in field and lab settings to determine the dissolved oxygen content of water samples.I also have a Jenway and an older device which still work, but for teaching purposes we needed several and Extech looked like a great alternative so I purchased three. While, the existing Jenway devices and one of my Extech DO600 Waterproof ExStik II provide measurements that agree with one another, two of the Extech DO600 Waterproof ExStik II devices provide readings that are completely impossible.The devices were calibrated in exactly the same way as each other. I raised the issue with the sales team at Extech because they do not provide any customer service contact details but I could find a sales email address online (unsurprisingly). Nobody has answered my query, so presumably they are happy to sell the devices, which do not work, and they prefer not to hear from customers and do not intend to deal with faulty items.It's very disappointing as we have a limited budget and this has cut into it as we'll need to source alternative devices without receiving any refund, or even any suggestions as to the source of the fault/troubleshooting.
