I have been using bluelab products for over eight years. Highly accurate but priced a bit steep for many ordinary gardeners - If you are looking for lab quality and extreme accuracy look no further. All blue lab products that I have tested which include their combo meter, soil ph pen, and the guardian meter have all performed excellent. The ph probes must be kept clean and submerged in a solution (I use tap water that is frequently changed out after each use). To keep the probes lasting you must keep proper maintenance and always be sure to recalibrate one to two times a month for best results. Calibrate in ph 7.0 solution first and follow it up with 4.0 until your ph probe has a check mark in which it should now be perfectly calibrated and accurate. Be careful not to drop your ph probe as they can be fragile that most likely would resulting in accurate readings or cracked glass.

I have an automated growth chamber (not from Bluelab) and was curious if these would be plug and play in the system. Sure enough, they were! I've bought almost 2 dozen for all my different setups, and, aside from minor issues likely related to user error or shipping, every probe has worked well.Checked each against a separate calibrated meter and found all probes to be fairly accurate as well. Drift was easily corrected by calibration.

I have been using a bluelab Ph tester for more than a year. Fantastic unit, holds calibration for months at a time when taken care of properly. The first Probe lasted most of a year, I bought a replacement from a local shop and was surprised that it was a different Probe than the factory one. It was plastic as opposed to glass. It did not keep calibrated at all. I complained to the shop and was told they didn't understand what my problem was. The PH tester module isn't cheap $230ish dollars, I did not want to have to buy another complete unit. I was hoping that I could replace the probe with something resembling the factory unit. When I got the one I ordered from Amazon I was very happy. It is the exact same as the factory probe! It is made out of glass! It holds calibration! Once again Amazon saves the day!. Thank you.

This was my third attempt to get a functional ph probe from bluelab. I was hoping this would be the charm. But not the case. I love my bluelab my soil test probe and the combo meter. Never had a problem with the meter or the soil prob. Great products. Bluelab needs to improve their QC ON SHIPPING THE PROBE. Othe companies have the solution. A large tightly sealed bottle with storage solution. Checkout the Atlas scientific probe. Look at the size of the container the protection and its ability to contain and prevent the spilling of the storage solution.I will be writing a review on that probe. Spoiler alert. It’s an excellent probe and it works with the bluelab meter.“COME ON BLUELAB GET YOUR ACT TOGEATHERâ€

They send many of them void of the required storage solution. Either it leaks out during storage at warehouse or when shipped. In any case they are not suppose to be stored dry so when you open the box and see a dry probe you have to get it replaced. Once you get one that is properly packaged with solution they work great. I have had a pen last almost 3 year with proper care. Then took 3 tries to get one that was packaged properly. Although they did replace them until I got a properly package one. Just annoying cause you can't buy an extra and keep it the box sealed in case you break one cause you have to make sure they didn't send you a dry probe.

The problem with these probes if 'used' or refurbished is if the probe's been wet and dries out it is DEAD and give you an ERR reading. This came used but the probe was wet in the case- excellent job saved me a ton- thank you!

It worked beautifully and the price was right! These things are so fragile and I was so worried it would be expensive to replace. Fortunately, they are inexpensive and available. Recommend this seller!AAAAAAAAA+++++++
