The media could not be loaded. Blue lab is an excellent product works great. This is not a review about the product is about the seller. If you need one go somewhere else this Mickey Mouse operation not suitable for my standers anyways, if they’re willing to send something like this out that speaks for itself trying to sell used products I’m assuming for new pricing I’d be returning this product back to them. I’m buying it somewhere else I recommend, anybody, considering buying from this seller not to do it ... show more

    • Exact replacement. Works perfect
Exact replacement for PH testing. Install the box type connector, calibrate and back up and working. Must buy 4.0 and 7.0 calibration liquid.

    • Good PH probe just tough to get a properly packaged one
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. ... show more

    • Extreme accuracy comes at a price but well worth it.
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. ... show more
