- Lab Grade pH Probe - Neptune Systems
Neptune Systems tested many probes until they found a manufacturer that would provide long life as well as consistent and accurate performance. Lab grade probes are held to tighter standards and use higher quality materials allowing a longer life, and holding calibration longer than standard grade probes.
- Replace a worn out pH probe
- Purchase a pH probe to add to your Apex Lite System
- Purchase a pH probe to use with your PM1 Extension Module
Note: Calibration solutions sold separately
The Neptune Lab Grade pH Probe is great for any monitor or controller that requires a BNC style connection with a high quality probe. If you are buying a new controller that doesn't include a probe like the Apex lite, adding a new tank and need another probe, or just replacing your worn out old probe look no further.
Lab Grade probes will hold calibration longer, and generally just last longer than standard grade pH probes.
Note: Calibration solution not included. We suggest ordering multiple packets of calibration solution to have on hand, and calibrating every 60-90 days for reliable results.
Awesome By ITeachIT on 4/6/2018ITeachIT would recommend this product to a friendI have had my Lab Grade pH probe in service for almost 2 years and it still is accurate and has only been calibrated twice.
only worked 6 months By joe on 1/15/2018joe wouldn't recommend this product to a friendOnly worked 6 months even after cleaned and recalibrated its still off by 0.12. Next time I will spend a little more for the Double Junction pH Probe. I always have 2 probes so I can see when they need to be calibrated
Another GREAT product by Neptune/Apex By FLSharkvictim on 2/24/2017FLSharkvictim would recommend this product to a friendSuper Accurate and HIGHLY recommended on your Apex controller!
Awesome By George on 4/1/2016George would recommend this product to a friendGreat probe that works well. Just make sure you calibrate every few months and keep it clean
Good quality By Don on 3/4/2016Don would recommend this product to a friendI set it up as a second pH probe in the Neptune to monitor my calcium reactor. So far it's doing a good job. PH in my tank has been super stable. Calcium reactor pH is staying where I want it.
Calibration issues By Dave on 3/2/2016Dave wouldn't recommend this product to a friendI can't get this probe to calibrate no matter what I do
Excellent choice By Randy on 6/10/2015Randy would recommend this product to a friendThe prob work great
Lab grade ph probe replaced By Rafael on 5/29/2014Rafael would recommend this product to a friendI found that my pH lab grade Pro was damage when I open my Apex system. I called customer service and they politely replace my probe with a new one for no-cost, they have excellent customer service and I will purchase from them again, thank you
Love this pH probe By Kyle on 12/24/2013Kyle would recommend this product to a friendI have tried and used several different pH probes and this one is definitely the best. This is my 4th Neptune pH probe and I always get what I expect...............a probe that is accurate and lasts a long time. This is definitely my "go to" probe from this point forward.
Good Probe By Jim on 12/3/2013Jim would recommend this product to a friendCalibration fluid would have been nice to be included for initial setup. Also should be noted that there is a cap on the probe that needs to be removed prior to installation. Out of the box it reads just about dead on however.
Good probe, accurate 2.5 years and still going By Brian on 7/19/2013Brian would recommend this product to a friendI got this system with my Apex controller over 2-1/2 years ago. Last week was the first time it went significantly out of calibration. I soaked it in vineager for an hour to dissolve any calcium buildup and then did a long recalibration and is so far working well.
information needed By Bill on 5/7/2013Bill would recommend this product to a friendEasy to set up once I realized I needed a pm1 to hook it to. I think this should have been mentioned in the description. You could have sold me one. Once installed and calibrated it works great. Here again should have told me it didn't come with calibration fluid.
There are no videos related to this product.
What is the typical lifespan for this probe?
This probe should last you for at least a year. Be sure to recalibrate every 30-90 days and you should be good to go. Have a great day!
