Long Body pH Electrode with BNC Socket Probe 300cm Cable 0-14pH for pH Meter, pH Controller pH Device Economical Sensor

Works perfectly with my blue lab.

This is the second one I purchased. I am pleased with both purchases.

I like the fact that it fits my blulab ph meter. From 2001 none the less. I've yet tried to calibrate the probe, but I suspect I won't have an issue.The probe itself looks well built, and 64.00 USD cheaper than the replacement blulab probe. (3 times)

Delivered better than I expected! I have 6 different pricey pH units. My main ones are the bluelab guardian. The pH probes made by bluelab are $80-100 each, and are supposed to last 18months….but it’s more like 4-6 months….these not only work perfectly with the bluelab guardian, but they are 80% cheaper …AND they were actually slightly more accurate than the bluelab ones after calibrating. Stop wasting money on Bluelab replacement probes and just buy a ton of these.

worked for one week. waste of time and money

It works!

so far so good. this was purchased as a replacement for my ph controller

I have been tinkering with DIY pH projects now for quite some time. I have tried 3 different probes now and this probe out performs all of them so far. I am using this probe with a sensor board from AnyLeaf. It is compatible with that board and any that have a BNC style connection. I would recommend this kit to anyone looking for a replacement. The temperature readings are spot on as well as pH. I only had to calibrate this one time and it worked. I have tried others that would not hold calibration very well, and this one holds flawlessly. I am using this in a hydroponics system where I monitor pH conditions 24 x 7. I get very accurate real time readings with this unit.
