Best B*Labss replacement I've found!
So far this is the least expensive, accurate, and durable B*Labss replacement probe I've found! Easy to clean, holds up to rough daily use, and maintains accuracy throughout the calibration duration. Love'em!

I do not recommend very cheap doesn’t read correctly
This PH pan is very cheap first of all the wire. It’s very short second ball. It gives you off numbers I definitely do not recommend it.

It has a short cord
Seems to be working well, however, the cord is very short. I probably just overlooked it in the description but the cord is only about 2 feet long, replacing the 10 foot cord on my previous probe.

It works well with my pH meter (vwr SP70P), and saves a lot, comparing it to the $$$ Orion pH probe.
$$ compared to $$$, and it works well!

Stable and works well.
Only have been using a few days. I will update again should my experience change. I find it stable. I use it permanently in my hydroponic system along with a scientific atlas board and an esp. appears to be well sealed.

Mixed results
I've bought a dozen or so of these probes over the past year or so for our Service Technicians who use them in the field to measure pH of produced water from oil wells. I decided on this brand because they are less expensive than the Oakton probes but can be used with the Oakton meters. I first bought one for myself to test in the field and I found them to work as well as the Oaktons. However, over time these probes have proven to be less durable than the Oaktons and I have also come across a couple of them that are defective right out of the box. The durability issue has to do with the plastic. The plastic tends to wear out faster. This was reported to me by our QC lab technician who I gave a couple of them to to use in the lab. Versus the Oaktons, the Apera probes do not stand up as well. I'm not suggesting anyone not buy these probes, but based on my experience with them they are cheaper for a reason.

Accurate pH Controller Probe Replacement for Hydroponics!
Used to replace an old broken pH probe that originally came with a pH injection controller for hydroponic systems.The probe and controller had no trouble with compatibility and pH readings were very accurate upon arrival!
