Very reliable By Fishers Coral Reef Farm on 11/25/2015

We do not keep the probe in tank water 24/7 due to algae growth within the reference junction. We also do, and recommend, storing the probe tip in pH probe storage solution. With this practice, we find the BRS lab grade probe obtains a stable reading with 7 and 10 calibration solutions during the calibration procedure. Other probes begin to take longer to equilibrate after about 12-18 months of use. With these probes, we also find that our monthly 'as found' pH during calibration is very close to the 'as left' and often does not require any calibration adjustment on the meter. We'll be buying another one of these to control our CO2 reactor. Unfortunately, that one will have to remain in the system water 24/7.
Works well maintains calibration By Richard on 11/19/2015

This probe, in my opinion, performs as good or better than Neptune probes.. Have used one for over a year and I test 3 probes in my system evrey three months. I use a borrowed pH tester and test before calibration. I also move the probes between tanks sometimes and i have never had to calibrate the BRS probe.

Very happy with this probe. Hooked right up to the Apex, calibrated quickly and up and running in no time. Happy to have the extra quality at a lower cost :)
Love it By Fish tank Jeff on 5/11/2015

Ok so I finally decided to give this probe a try and I love the quality of it and it calibrates very fast, it reads right on, will buy this one again when needed, works great with my reef keeper elite.

Great probe for the money. Works well and calibrates fine. You can pay more elsewhere but why!!
good probe By nick on 12/15/2014

This is a good choice for a replacement probe. Easy to calibratcalibrate, cable length is the same as the pinpoint. No issues hooking it up or with its performance so far.
Good quality By Don on 10/5/2014

It's accurate. Easy to calibrate. I've only used the Apex probe but this is definitely a better probe.
Very Good PH-Probe By Alex on 9/15/2014

I have been in this hobby a very long time (20+years) and have gone through alot of PH-probes.
I have to say.... The BRS Lab Grade PH-Probe is one of the fastest probes i've seen to calibrate, it looks well built.
I will be buying another soon for my Calcium Reactor Controller.
Very Nice BRS!
Calibration Off By JohnD on 7/13/2014

This is my first time going with something other than the Neptune Probes which don't fit correctly into my Calcium reactor so I figured I would try this one. Build is solid and it fits perfectly but there appears to be a problem with consistent readings. After calibrating multiple times it always reads perfectly on the 10.0 side but retesting after calibration is always off by a couple hundredths for the 7.0 side. Generally I end up with a 6.97 or 7.02 after calibrating. I always rinse after calibration in RO water then test readings in fresh calibration fluid. I did this at the same time I calibrated my Neptune probe and the Neptune was spot on every time.

Best probe bar none By Manfred on 4/5/2014

Lab Grade normally means this is the best probe we offer. Well, why would you ever offer less than your best? From the very start this probe screamed true lab grade with the ultra secure housing covering the probe's lense; much more than the usual thin plastic push on cover other manufacturers use. You know, the ones with the salt creep on the plastic housing cover right from the factory? When I calibrated the probe the parameters settled quickly giving you the sense that accuracy would be greatly enhanced. My old probe was reading my PH at 2.0 and I had reason to believe that reading may be low. The BRS probe read 2.3 and was more in line with what I felt my PH level was all along. The difference with the two readings were not earth shattering but I trust this probe with providing consistently accurate readings. In reefing, we want to try to stay a step ahead of impending problems. This probe wii help me with this aspect of my preventive maintenance program. Buy it! You'll like it!
