Great By Jim on 12/15/13Jim would recommend this product to a friendFantastic probe and excellent deal
Looks to be of excellent quality By Jan on 12/6/13Jan would recommend this product to a friendThis lab grade probe appears to be constructed of much higher quality compared to the Digital Aquatics probe that I have been using. After calibrating with my RKE it provided quick and accurate results on known solutions. Time will tell to see how long it takes to deviate from the actual measurements.
Worked Like a Charm By Micah on 10/18/13Micah would recommend this product to a friendAfter calibrating on my AC Apex the probe gives me an accurate reading (tested against Salifert's PH Test Kit) and appears to be working well.
Good Quality and Price! By Andy on 8/15/13Andy would recommend this product to a friendExcellent quality. Reading is very steady. Does not jump around at all like the other cheap probes I have used. Very accurate and craftsmanship is of high quality. I will come back for these when I need another replacement. High quality just like the expensive probes, but with a nice price tag!
so far so good By gary on 8/1/13gary would recommend this product to a friendOnly received the probe last night and calibrated it I'm using this for my calcium reactor seems more accurate than the other probe I was using

Is the BRS lab-grade PH probe compatible with neptune apex controllers?
Bulk Reef Supply Hey Annie,
It sure is. All of the controllers and ph probes in the hobby are interchangeable and compatible. You can even use a reef keeper pH probe with the apex as well.

Is the BRS lab-grade PH probe compatible with Pinpoint PH monitor by American Marine?
Bulk Reef Supply Hey Robert,
It sure is. Pretty much all the probes/monitors/controllers in the hobby are interchangeable.

will this work with a reefkeeper light with sl1 module head unit and PC4 already have one ph probe & temp probe. I the ordered sl2 module and want to add ORP/2nd pH control for a calcium reactor where a 2nd pH probe (one for tank one for Ca reactor) really be a must have, and $40 for a HQ one is a great deal. Please let me know as soon as possible if this will work with my setup. Also which if any of the ORP probes you sell will fit into the reefkeeper light module?
Bulk Reef Supply Hi Steven,
The pH probes are universal and interchangeable. You can use this probe to replace a DA probe, Neptune, probe, etc. The ORP probes are also interchangable though its worth mentioning that the SL1 has a pH/ORP probe ports. If you ordered the SL2 it has a single pH probe port and then a salinity port (no ORP).

Hey guys, does the probe need calibrating before use?
Bulk Reef Supply Hey Andre,
We get this question a lot. This is a bit of a misconception as its really common for folks to say "calibrate your probe" but what they really mean is "calibrate your controller for your new probe". A pH probe is actually a "dumb" device, it has no electronics in it so you actually never calibrate the pH probe itself. What you do is calibrate your controller when you add a new probe to it. Your basically teaching the controller how to understand the new probes values/readings. Generally you should always calibrate your controller when you add a new pH probe and your controller will have instructions on how to do so!

Does the brs ph probe come with calibration fluid?
Bulk Reef Supply Hi Anthony,
It does not as you may need different solutions for different applications. You would want to pick up the the calibration solution of your choice. Personally I recommend the Milwaukee for our probes because the tall narrow pouch makes it easy to get the probe submerged.
BRS Lab Grade pH Probe Features:
Double Junction Probe: A double junction probe has a second seal and junction found at the center of the probe. The double junction design adds to the cost and complexity of the probe but they are recommended in instances where the probe will come in contact with proteins or heavy metals. When these elements come in contact with the silver within the probe gel they can precipitate on the porous junction and clog it which can cause drift and shorten the life of probe.
The double junction design used in this probe has a second junction in the center of the probe which creates two chambers within the probe. The first one is filled with the reference gel containing mostly potassium chloride, silver chloride and reference probe. The second chamber has just reference gel containing mostly potassium chloride. This design prevents precipitation by keeping the silver away from the second porous junction at the bottom of the probe which is exposed to the aquarium water.
The BRS Lab Grade probe uses pelon strips as a junction material which is a true electrochemical insulator which allows a complete circuit between the reference probe and the tank but allows a very minimal transfer of elements found within the probe or tank. The pelon strip is also much easier to re-wet than the ceramic junctions in the case of accidental drying out of the probe.
The BNC connector is also made to higher quality specifications with superior insulators between the shell and center pin to reduce noise and increase accuracy. The outer shell on the BRS Lab Grade Probe is made using epoxy rather than less expensive polycarbonate which is what most probes use because it is the most inexpensive material available. The epoxy shell is a highly resistant material and inert to a wide range of materials making this one of the more chemically compatible options available for probes like this.
