For 130$... this is a steal!!!! Ppm probe and all included.
The ppm pen is pretty bullet proof, I've had mine at least 8 years and it is rarely too far from calibration

The ph pen however I did have one fail on me and the 2nd was a little wacky and read slow. I love my leap probe it is working great

TDS the cheap ones works very well I never will buy one more expensive then 20 bucks my old one works for 3 years cheap one! Bluelab is a problem because you can't replace the electrode!

This one I here is great https://www.amazon.de/Apera-Instruments-Genauigkeit-austauschbare-Temperaturanzeige/dp/B01ENFOIQE/ref=mp_s_a_1_16?crid=3LMYNP08WN6VZ&keywords=Ph+Meter&qid=1641563365&sprefix=ph+meter+,aps,185&sr=8-16

I agree, I didnt end up liking that blue lab model
I have heard great things about apera! That is cool you can replace the electrode
Thats why i bought the bluelab leap probe, it is replaceable, faster measurements, and will do direct media tests

I have the Option to Buy the Apera PH60 for 65 Bucks only used for 3 times the seller told me ore this one for the same price but without warenty but the electrode is maybe changeable. Which one you prefere?

 

[magnetik]

Apera has flat sensor pH probes that are much more durable/protected but you end up losing TDS (If a combo probe is being replaced). I can still use the TDS sensor on the original combo probe if I ever need it. Seems pricey until you replaced pH probes a few times cause you broke them tapping water off esp with combo probes since they are more $$$.

And know? I can't buy both pieces... What you mean with TDS? You would not buy the Apera PH60 in my case?

Why buying the Apera PH60 for 70 bucks when the PH20 cost 50 bucks ok electrode is not repalceble but she cost between 40-50 bucks for this money I can buy a new PH 20 Pen.

 

[Fiete]

I have bought the Apera PH20 for 50 bucks on Amazon with Warrenty. I can also Buy the Apera PH60 for 55€ New but without Warrenty that's the problem I love to buy it but when something is wrong I can't change it so the PH20 is a good decision too I can send it back in 4 weeks if i don't like it but the PH 20 has 4500 Votes with over 4,5 Stars that's Insane.

how much is a Milwaukee MW 101 for you? i love mine.

 

[james of tucson]

I hate ph meters! I've bought $14-$250 models. All difficult to maintain and less than trustworthy. Will try the Hanna next...ugh

If they're all bad, I'm thinking to go for the $15 Vivosun :-/ My Bluelab experience wasn't great, and I don't understand why they get so much love. Give me ten $15 meters on a repeat order and they'll last longer than my $150 pen did. I'm tempted to go back to dip strips to be honest. I think I can get pH test paper on 10 foot spools

I think that's the answer depending on how readily available that replacement sensor will be. I don't want to buy a $100 meter if it's going to fail in the same way $15 meters do.

i've had mine for probably 8 years or so. same probe. i calibrate it once or twice a grow. and i store the probe in distilled water (the milwaukee rep told me to do it that way, not in KCl solution). and the probes are readily available

You'd be far better off with drops than a cheap inaccurate pH pen.

I'm convinced most folks who only are willing to pay $15 for a meter are not going to pay $20 for some calibration fluid. let alone proper storage.

 

[ozziebud]

Blue lab soil pen then ya can test water and soil if you wanted to

 

[rkymtnman]

guess you don't use kelp, fulvic, etc. or anything brown?

 

[Billy the Mountain]

I do use FloraNova which is pretty dark; it doesn't matter with the 5ml in the tube

 

[Antidote Man]

OAKTON EcoTestr pH 2+ Pocket pH Meter

got one for 20$ shipped on ebay! They go for 65$-85$ on amazon, etc, and are worth every penny.. durable, precise and all that

maybe my mix is darker? the drops all came out a puke brownish color for me. do you use the GH brand of drops? i love them as a backup when just usng plain base nutes.

I think the test papers are always a reliable solution, but how would you tell the correct pH if the nutrients add color to the water? What other solutions would you recommend for testing pH after adding nutrients?

 

[bam0813]

Question for guys using drops how do they work if the nute mix has a color of its own? Thinking about using salts indoors. I got a pen when I first started because of that but switched to soil organic by the sec or third run
Edit: sorry should have read thread above lol

 

[bam0813]

Hey guy's

Can I use for cleaning the electrode a cosmetic brush looking better for cleaning..

The cleaners I’ve seen appear to be cork like pad more than a brush
