Style: Soil pH Pen + pH Care Kit


Features

  • Soil pH Meter Pen for Soil, Hydroponics or Water- Use for soil and water hydroponics including growing tents, swimming pools, drinking water, aquariums, fish tanks, coco and rockwool. The Bluelab digital pH soil meter provides a compact, quick, and handy way to manage the success of your crops to ensure maximum uptake of nutrients. Help your plants thrive by measuring pH and temperature to ensure that they are always in the optimal range.
  • Comprehensive Probe Care Kit Included-The Bluelab Probe Care Kit pH includes everything you need to maintain your pH pen, including probe care instructions, 18 ml single-use Bluelab Solution Sachets for calibration (two each of pH 7.0, pH 4.0, KCl solutions), and three plastic cups for mixing solutions.
  • Super Easy to Calibrate- You can set up our Bluelab digital garden soil tester with a simple two-point calibration process. Remember to calibrate the handheld meter before first use. Our efficient Bluelab pH soil test kit comes with a 30-day calibration indicator that can be easily viewed on a backlit LCD display. The digital pH meter will come with 1 x 20-ml sachet of each pH7, pH4, and KCl for INITIAL HYDRATION and calibration.
  • Advanced Dibber Now Included- Extend the life of the pH soil tester with the game-changing dibber or dibbler. The probe cover now acts as a dibber. The dibbler allows you to first press your pen into a substrate, remove the cover, and then take a reading in the indentation. This protects your Bluelab pH pen's probe, reducing the risk of wear and tear. Automatic temperature compensation ensures accurate readings. Bluelab's digital soil pH meter will take measurements in increments of 0.1 pH.

  • It works!!!
Style: Soil pH Pen + pH Care Kit
Do not waste your money on the cheap ph testers/meters. This works as described with repeated accuracy. Simply follow calibration instructions.

Style: Bluelab Soil pH Pen
So I found this pen to be such a life saver. I loved the way it tested the ph of my plants in an instant. I went around my little nursery and was able to test them all. I had crazy results, no wonder my plants were not doing well. So they found themselves back on their way. They started to look sad again, within about a week and half. Something wasn't adding up with my mix, there was no way the ph should be that high and I should have to be adding that much ph down. So I recalibrated, and same thing. Who knows? next day half my plants appear dead. I tried to recalibrate again, this time it would not pick up right, the 7.0 solution was picking up 10 and the 4 was picking up 7. I returned and amazon got me another the same day. So I calibrated that one, the solution rang in at 3.1! I was p***ed So I think just got a dudd. I got this last probe march 1st. It started acting up 3 days ago, the screen started to morph to unreadable, temps reading over 180. Are you serious!? I use this multiple times a day. this is a huge expense as right now I am entirely self funded. I work on research on propagation of endangered native plants. There are downright impossible sources to come by at any rate, but to have them fail like this, from errors of a pricey product that I purchased to make it easier to restore them to the environment, this gets them a rating of 1. My heart literally breaks with each loss of plant life that I lose. I cannot just go and buy this stuff at Walmart. I am at a loss and have no idea where to go from here. ***update, I went ahead and got a new pen less than 1 week ago. this makes three in less than 2 months. I have had in the past 2 days, 2 seedlings that have never been cultivated grow. by changing the ph just a small amount. Ph meter worked great all day. Tonight, its not working, screwed up reading, always reads 7.3, will not calibrate. never ever again bluelab. The Dollar tree makes products that last longer. ... show more

  • Perfect. Absolutely Perfect.
Style: Bluelab Soil pH Pen
Invaluable tool in soil or coco. It also tests liquid pH as well. I also have a cheap $15 pH pen and it is not worth the hassle. It’s even got over 300 5 star reviews and it’s still not nearly as accurate as the Bluelab pH pen. I use it in The Growing Rack and I couldn’t be happier with both purchases. They are a match made in heaven. The pic shows the inside of The Growing Rack and my nute lineup. ... show more

  • We're starting at 4 stars, then go from there.
Style: Bluelab Soil pH Pen
I received my probe in the mail today. I was really confused as to what the KCL fluid was, because there was fluid in both the cap and inside the probe it seems.....I feel like the instructions could be clearer but I figured it out. So after powering on I noticed there's no check mark next to the pH label meaning that it needs to be calibrated. So I can't even use this right out of the box. The pen should not only come calibrated but it should also include one small pouch of calibration fluids as well as KCL fluid, just for backup. I understand these things need to be sold separately as they get used up pretty quick each season, but I feel I should be able to use this right out of the box. What has ended up happening is that there wasn't enough KCL solution in the dibber to bathe the probe, and so I had to add 2 drops water to the dibber and soak it overnight (it really only requires a couple drops of water, which you think it would require more by looking at the dibber but nope). So I have to do two things: let the probe soak overnight now that there's enough fluid inside, and now I have to order the pH calibration fluids and wait for them to come in the mail so I can calibrate this thing before using it. I admit, this is a bit annoying. I understand that maybe the calibration will be lost from when this pen is produced in the warehouse and by the time the buyer receives it. But that's why you should include a little bit of calibration fluid with the pen so I can calibrate it, allowing me to use it right out of the box. Anyhow, it has nice packaging and is a nicely put together device from what I can tell. I don't expect to have any problems and trust it will do its job reliably. I will update this review in the future if necessary. ... show more

I got the solution to assess the calibration of the bluelab pH pen and been detecting consistent data for water and other solutions. Perfect for knowing how to keep my drinkables at a higher pH so to balance my acidic diet of foods. In doing so, I detoxify my body every day and help the digestion of foods work as it should. In this age of modern polluting factors (a mountain of factors, really) our basic water and other fluids are poisoned by chlorine, chloride , flouride, and other unwanted pollutants. These products change the water pH. Our natural streams (with higher pH because of magnesium and potassium) are no longer the standard we evolved to intake. This other water, delivered via pipes or with well shock treatments with Chlorine isn't part of our evolutionary diet. So the Bluelab Pen permits me to make sure what I drink is going to be something I've evolved to drink that helps me balance the toxic effects of too much of one thing (acidic foods that need to be digested and distributed by alkaline fluids). ... show more
