PH Pen Meter

[revhtree Verified Admin]

Do any of you use a PH meter?

Nice set of tools for a good price. Was going to buy a new test kit to see how my PH probes were performing and saw this.

One whole hour and no response!?!? I'm leaving this forum!!

Those pH probes have to be calibrated the same as the probe on your Apex. Probably would be better off just putting a second pH probe on the Apex to compare against. At least then you would have control with it and a constant reading

pH pens can be good, but I'd really want two point calibration. Not sure what this one has.

The one I have is cheap and only has one point calibration. However, I have standards at the house that I can always check against, so it's less of an issue. Whenever I get suspect readings on my Apex pH probe or when I want to check pH on the QT, I pull out the handheld

As long as you can check a pH other than the calibration pH (like calibrate at 7 and check 8, 9, or 10), then you can know how it is doing. Single point without checking doesn't really do the trick.

I've got one that I use to quickly check the tank. It came with 2 calibration solutions so I'm not sure if that makes a difference or not. But I find it says my tank is a quite consistent 8.2 during the day and 8.1 at night.

Yes, I calibrate at 7 and check against solutions with pH of 4 and 10.

Here at Hanna we are a great source for affordable, accurate and easy to use pH pens that are great for aquariums!

The HI98108 is a waterproof pH/temperature pocket tester pen that has automatic two point calibration and a great new design. This meter features an exposed temperature sensor that will provide rapid automatic temperature compensated measurements. The simple two-button operation provides one button for ON/OFF, the other for calibration. Being lightweight and only 0.7" thick, the pHep+ is extremely ergonomic and fits comfortably in your hand.

We also have the HI98107 which is the same design but has a resolution of 0.1 rather than 0.01 pH read out.

All units come with a case, calibration solutions and electrode cleaning solutions!
