Hi. I purchased the vivsun ph and ppm meter. The ph meter jumps all over the place and has a different reading each time i test the same solution. I would probably feel safer with a ph drop kit. The ppm meter seems ok.
I do not have time guessing what my ph is. Can someone suggest an accurate alternative? Preferably in amazon. Thank you.

Got this after ruining a couple plants when my $10 Amazon ph pen went wild.

It’s like $45, and having the calibration solutions is great for peace of mind.

growing in coir the ph pen is the one thing I regret cheaping out on.

I had a bluelab for a decade
But when it came time to replace I went with a Hanna Grow-line pen and the orange Hanna pen
Both available on Amazon for under $40

I like Bluelab just overpriced IMO

Agreed, Bluelab is good but nothing special and seems overpriced. I'm very happy with my Milwaukee MW102, I've had it 4 years and just bought an Apera ph80.

I am using this generic pen from Amazon, currently $37.99 with a 5% coupon.

Just be sure to keep moisture in the cap and don't let the tip dry out. The first one I had dried out and there was nothing I could do to resuscitate it.

Also, use tap water, do not store the tip in distilled water, they don't like that for some reason.

I tried this Apera $120 combo pen (now $135) and it didn't last a week.

I had Apera send me a new tip, that also didn't last a week. I sent the kit back for a full refund.

This generic combo costs less than the price of the replacement tips for the more expensive pens, so even if it only lasts six months I am still better off than buying a replacement tip. I couldn't find an expensive pen with a warranty for the tip longer than six months.

I don't know if you got a defective unit or if there was user error, but my apera meters have lasted me over 2 years with zero issues. keep them clean, store them correctly, and calibrate them periodically and they are great.

Beware buying Apera from AMZ... My first 2 8500s were old models, and were cheaper, but I had calibration problems with them. I sent them back to AMZ and bought direct from Apera. Not cheap at $479, and a new Swiss glass probe every year at $140, but about as accurate as it gets. Measures direct soil, or liquid.

Yes, it was diasppointing but I did everything they told me to do. I just decided it didn't make sense to keep the expensive meter when the cheap meter is working just fine. When it dies, I don't care.
