  • Quality not worth the price premium By on 1/24/2017

    I still not convinced this is better than a $10 probe from ebay. The first probe I got, died on me in just couple months. Its read went from 8 to 6 back to 8 in terms of minutes, then eventually stayed in 2. Got a replacement a month ago, it is already start jumping down and back up. Who know how long it will hold this time. Not durable enough for its price tag.

    I have both Neptune and BRS probes. The Neptune is used in the fuge tank and the BRS in the calcium reactor. I calibrated both when I purchased the controller and then again about 3 months later. A very minor adjustment on one of them the second time around. Now just today I pulled the probes more for cleaning than any other reason. Soaked them in vinegar, peroxide and ro water to remove the crusty critters and coralline. Not so much on the BRS probe but it also lives in a high calcium environment. Cleaned up rinsed and BRS probe checked in 4.0 and 7.0 solution. Settled at 3.99 and 7.02 after six months use. Spot on as far as I'm concerned. No adjustment needed. The Neptune probe did just as well at 7.0 and 10.

    That leaves two more things to consider. Having lab experience, we typically replaced pH probes every couple of years. Kind of what I expect. Maybe I'll be surprised?

    Other than that is cost. Kind of a no brainer for me but I'll leave that to all of you to do your own math. Looks like another home run for BRS as far as I can tell.
  • it ok By on 4/8/2016

    it would be better if come whit the calibration solution packages
  • Excellent By on 12/17/2015

    Why pay more for average quality if u can have simply the Best at BRS, keeps calibration for months!!!!!!
  • No problems here! By on 12/13/2015

    I originally tried to go cheap and bought a pH probe on eBay that never worked right from the start. I guess that's what you get when you pay $10 for a pH probe. I did manage to get this probe during the Black Friday sale which made it the same price as Apex standard Ph probe. I didn't even calibrate it yet. I stuck it in the probe mount in my sump, plugged it into my mp1 module, and checked the reading. I then performed a ph test on my water and it was spot on with the probe! Checked a couple more times and have found this probe to be rock solid.
  • Very reliable By 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 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.

  • Great By on 7/31/2015

    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 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 at a great price By on 4/26/2015

    Excellent build quality. No issues calibrating with my Apex. I
