Bluelab PENPH pH Pen, Digital Meter for Water with Easy Two Point Calibration and Double Junction Probe Test Kit for Hydroponic System and Indoor…

Should have listened to the other reviews saying the same thing. Product arrived with salt buildup and scratches/scuffs on the pen. This leads me to believe the pen has been previously returned, which only begs the question: why?

Bluelab pens come highly recommended, and the quality of this pen is questionable to say the best.

Following instructions on calibration after it’s primed with storage solution will tell me if the pen works, but the fact that this pen is not advertised as USED is blatant disregard for your customers.

I bought this blue lab PH pen wanting more accurate readings than what can be provided with the solution PH testing kit. (Add drops to that small clear container, shake to agitate and record color reading) However this PH pen is a joke when it comes to consistency. My $2 testing kit consistently gives the same readings, however this PH pen seems to have a mind of it’s own with readings varying day to day with the same solution mixture. (And mind you I start with distilled water and use oral syringes for measuring so I know for a fact I should be getting very similar readings from feed to feed).

So I gave it the benefit of the doubt and bought some more calibration solution. Sort of helps but again it seems to only maintain it’s baseline for a day before falling out of wack again. For any new growers wondering if this is a worthwhile investment, I’d just pass. Get the small solution based PH testing kit and forget all the calibration and BS that comes along with this product. Cheers to all hope this saves even one person some money!

Well after 3 failed blue lab products,qll stored per service manual i purchased this meter making a grand total of 4,this meter was bought due to absolutely needing a ph reading while waiting on the technical support to basically tell me to kiss my ass,days and days went by with no response to a simple question….so this meter was purchased in a emergency situation,this one failed in 2 months…..warranty? Maybe but the hell with this,they are all going into the trash,these meters after proper calibration every 2 weeks both ph/tds have been absolutely nothing but problem creators,i would have been better off not even using them and taking my chances.never again.choose wisely.

Not a happy camper here, no where in the description does it state that your gonna have to spend another 50.00 on calibration solution, cleaning solution, and hydration solution. And the tiny packets that come with it isn’t enough to even get you started on hydrating the unit. Come on bluelabs and Amazon get your stuff together. This pen is already expensive, but having to add extras after the fact is ridiculous, especially if it’s not upfront in the description

Damn good meter lousy company won’t honor warranty. .the glass dome that covers the probe fell off in my reservoir and I didn’t notice until it’s too late it was flush when changing my nute’s. Now they basically told me to fo! 😠 very angry these are not flippin cheap! Be forwarnded the customer service sucks! 😠

I was scared to but another one of these after reading the reviews and sure enough I am sold a bunk pen! The packaging was already opened and the pen seemed used. It had a layer of crusted material on the probe and after Rinsing and calibrating the pen with what was provided it doesn’t read accurately like my blue pens I’ve had in the past. It’s off a few decimals and driving me crazy. Pretty disappointed in this purchase , if they know it’s something that drys out and doesn’t work properly they should cycle them out before selling them and not sell a meter that’s sat on a shelf for ages..
