Works great. Use it for both in liquid and soil/soiless mediums.

We grow 24 blueberry plants in our yard and like to monitor the soil pH which can really improve the yield when correct. Turns out, measuring pH is not so easy. The low cost probes tend to be inaccurate. This is a real pH meter that is much more accurate. However, there is some overhead associated with this type of pen. It does require calibration before use. In addition, there is maintenance requirements including making sure it is being stored in the maintenance solution. Finally, these do have a relatively short life and will need to be replaced after a few years.

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***edSo 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.

Never drifts and is very accurate

Bought this and the water one. This does both water and soil. Returned water one. Great quality, don't bother with the cheapos.

Works good I’ve always had good luck with blue lab’s products…

I discovered I had an issue with calibration only a couple of weeks over the warranty period and reached out to BlueLab Customer Care. BlueLab support immediately got back to me the same day ( within hours) and asked that I send them some more information on my calibration issues. Without any back and forth with them, and within a day they let me know they were going to take care of me. They honored their warranty and immediately sent me a new pen and a printed user guide/ grow booklets as well. BlueLab and their customer care are a sure cut above the rest. Recommended.

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).

Väsentlig information om produktens egenskaper utelämnas i produktbeskrivningen.Detta är en slit-och-släng-vara som säljs som en "investering" i högkvalitativ utrustning. Följande information framgår inte på Amazon-sidan alls men står i en finstilt text på tillverkarens hemsida:"Bluelab's pH products are charged with reference material which expends over time and use. The average life span of a pH pen is approximately 18 months."2000 kronor för något som inte kan användas nästa säsong? Tror de flesta skulle nöja sig med PH-papper om detta ärligt redovisades före köp.Min mätare höll dock inte ens för ett första test så jag slipper nog ur det här genom att returnera den som en garantivara. Tur i oturen. Som framgår av bilderna varierar avläsningen på samma ställe i jordhögen med 0,6 punkter och är olika vid alla tre mätningar. Jag har ingen aning om huruvida PH ligger inom intervallet som visas, men produkten visar inkonsekvent avläsning med 0,6 punkter och påstås ha en exakthet på 0,1 punkter, vilket alltså inte stämmer.

Nur diesesmal in einer Variante doe ich bislang nicht kannte und nicht mehr missen will.

Accurate even after a couple weeks it is on point with very low degree of error. Its a easy choice plus it also works as a ph tester and let me tell you the amount of times you have to re calibrate other ph pens is annoying but this one is the easiest piece of equipment i had the pleasure of using just be prepared to pay up because its not cheap

Brilliant piece of equipment as you would expect from blue lab don’t hesitate if you need to know the pH of your soil I will struggle to find something better to do the job
