Each, highly accurate, packet of PINPOINT pH Calibration Fluid contains ample fluid for calibration (about 30mL). Keeping your probes calibrated will lead to more reliable readings allowing you to know exactly what is going on with your pH.
- PINPOINT pH 4.00 is accurate to +/- .002.
- PINPOINT pH 7.00 is accurate to +/- .002.
- PINPOINT pH 10.00 is accurate to +/- .005.
Pinpoint recommends all electronic pH instruments should be calibrated monthly.
Compatible with all pH meters and probes.
Pinpoint High Precision pH Calibration Solution sold in single use packets.
Almost all pH monitors and controllers will require two points of reference to accurately monitor the pH that the probe is reading. You will want to use calibration solutions that are on either spectrum of the pH you intend to monitor. For reef tanks where the pH is normally 7.8-8.5 then you would want to use calibration solution 7.0 and 10.01. For calcium reactors on saltwater tanks or freshwater aquariums where the pH is normally below 7.0, you would want to use 4.01 and 7.01 for calibration of the probe.
4.01 pH - The lower threshold reading your pH monitor or controller will require for use with calcium reactors for saltwater aquariums, solutions below 7.00 pH and also most freshwater aquariums.
7.01 pH - Neutral pH calibration packet. This is used by almost all pH monitors and controllers for calibration.
10.01 pH - The higher threshold reading your pH monitor or controller will require for use with saltwater aquariums or solutions above 7.00 pH
Calibration packets can be stored in a cool dry area for up to 1 year.
does what it does By scott on 8/6/2018scott would recommend this product to a friendMore accuracy rating then other brand so I thought I'd try it. Would be helpful if the pouches were bigger though.
Works as advertised By Scott on 11/21/2017Scott would recommend this product to a friendWhat can I say, it works great to calibrate your PH probe!
Money well spent By John on 3/14/2017John would recommend this product to a friendNow with free shipping this is a complete no-brainer no more excuses not to calibrate pH.
Order more than you think you need By LBK Reefer on 10/23/2016LBK Reefer would recommend this product to a friendI think I have now wised up and order twice as much calibration fluid as I think I need. There is nothing worse than wondering if you probe is right and then find out you need to wait a week for a $0.99 item. Your probe is only as good as you calibrate it!
Simple & Easy By John on 7/17/2016John wouldn't recommend this product to a friendWorks every time. The key to keep the temp stable while calibrating is to keep it in tank water. I simply clip it to the top of my tank submerged in water and you're off and running.
good stuff By Mike on 9/19/2014Mike would recommend this product to a friendReally 11.00 bucks shipping if this is all I need?
Works as expected By Bob on 3/11/2014Bob would recommend this product to a friendExcellent product
Making sure it's right By Melvin on 1/19/2014Melvin would recommend this product to a friendThe fluid is great for making sure you are getting accurate readings from your equipment.
5 stars By jose on 11/7/2013jose would recommend this product to a friendgreat product would buy again
Great By Maria on 6/13/2013Maria would recommend this product to a friendCalibrates my pinpoint probe.
Works as described :)
great product, great price By Jason on 5/16/2013Jason would recommend this product to a friendused to calibrate my apex works great. and very good price
great product By GT-Reefer on 3/7/2013GT-Reefer would recommend this product to a friendI use the 7 and 10 and it works great. I pre rinse my probe in RO/DI, then start my calibration, but I will start using a little cal fluid to rinse away the water for a more accurate calibration.
Can Pinpoint PH calibration fluid be used to calibrate a Neptune Apex probe?
The Pinpoint calibration will work perfect with the apex pH probe. Feel free to let us know if you have any further questions!
I noticed in reviews for the ph calibration, comments about storing the ph probe in a shot glass etc. Are you supposed to do this or can it just stay in the aquarium it's monitoring. Sorry if this question seems illogical, I am new to the controller concept and have one on the way. Thanks,
If your going to have the probe out of the tank for a long time you don't want it to dry out, so it should be stored in a probe storage solution. As far as calibration itself goes, most of us just open the top of the calibration solution, submerge the probe in the pouch and follow the controllers calibration procedure.
