Description

Common troubleshooting: If probe is dry, please soak in KCL solution for 24 hours. Bluelab recommends our STSOL120 KCL Storage Solution, which is sold separately. Probe will not calibrate or provide accurate readings if it is dry and hasn't been re-soaked properly. Dry probes are normal and do not impact the quality of the product. The ultimate handy solution for measuring pH! Plants get their nutrition from minerals but they can only get all the right minerals they need if certain conditions are right. A key factor that affects food uptake is whether your solution is acid or alkaline. We measure this in pH. The Bluelab pH Pen is the latest innovation for hand held meters. It provides a compact quick and handy way to manage the success of your crops to ensure maximum uptake of nutrients. Teamed with our Bluelab EC Pen or Bluelab ppm Pen, you have a handy, convenient and accurate system for ensuring optimum plant growth and health. Now, isn't that handy? Features - Measures pH and temperature - Selectable units for ˚C & ˚F - Backlit LCD display - Double junction probe (not replaceable) - Successful pH calibration indicator - Hold reading function - Low battery indicator - Fully waterproof - Auto off function - Automatic temperature compensation.

    • I love it!
Style: PH Pen
First let me say DO NOT be discouraged from the one star reviews. I can understand someone being upset if they buy a new pen and get one that’s broken but if that’s the case none of us would ever own anything. It is absolutely impossible to buy anything that doesn’t have a bad review because of something that in many cases that has absolutely nothing to do with how the product works, go look up anything you own and love and someone had an issue, seriously go look and see, I’ve tried it there is nothing I’ve found that everyone loves. This pen is awesome if you are a grower and ph is vital and you want to be a next level grower. I’ve had mine 2 years and when it stops working I will immediately get another one. It does take a small bit of little effort to add a few drops of storage solution that you have to buy extra but that last a long time and it’s worth it to me. You add it after each use to keep it hydrated. If it dries out the pen is not ruined like some say but you might have to recalibrate which is easy after your first few times, especially with the step by step YouTube videos available to watch while you’re doing it. Just remember there are a lot of lazy incompetent people out there that all they want to do is push a button and be done with it and expect everything to be instant and do nothing else. It all comes down to how important ph means to you and it is very important to me. This pen is accurate and it’s awesome and requires very little effort to maintain and it has helped me take my growing to the next level. It also works great with my pool to, way better than those test strips they have that do work but not quite as accurate as this ph pen. Thousands of top growers use this pen and depend on it, you see them on YouTube all the time using it. I happened to run across the reviews looking for something else and wanted to see what the hater’s were saying and now that I’ve used the Bluelab pen a couple of years I felt I could give a genuine review based on my experience with it. So, now it’s up to you to decide. Good luck! ... show more

    • Bluelab Ph pen
Style: PH Pen
This is an accurate, economical Ph pen. I use it for swimming pool maintenance. Easy to set up and calibrate. It comes with one set of packets with storage solution, 4 Ph and 7 Ph. It is best to order extra packets when ordering the pen.

    • Dont buy the cheap pens
Style: PH Pen
This pen has lasted me a couple of years. I tried the cheap way out and went through 3 of the non-branded ph pens. I definitely recommend getting this one if you are in the market for a ph pen.
