The HI 98107 pHep pH Tester is a portable pH meter with a replaceable electrode and a non-clogging, replenishable fiber junction.
Featuring a large easy-to-read LCD screen, the tester provides fast and accurate pH readings in a rugged and ergonomically designed casing. The HI 98107 has a replaceable electrode and renewable reference junction, which helps prolong the life of this tester. With the replenishable junction, simply pull 1 to 2mm (1/8'') of the junction out with tweezers to recondition the pH electrode. This procedure can be repeated up to 15 times, before the whole fiber is removed.
The HI 98107 tester functions in temperatures of 0 to 50 degrees C (32 to 122 degrees F), and has a range of pH 0.0 to 14.0 (+ or - 0.1 pH) with a resolution of 0.1 pH. It is calibrated manually to 2 points. The HI98107 is an updated version of the HI96107 (pHep) pH meter. The dimensions are 175 x 41 x 23 mm (6.9 x 1.6 x 0.9") and the weight is 95g (3.4 oz.).
pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.

The meter has two point calibration at 4 and 7.
I use this instrument to measure pH during mashing. I use Bru’n Water spreadsheet [...] to predict pH since a lot of the mashing happens very quickly, making after the fact adjustments less useful (although I still mash for an hour and then fly sparge very slowly). I have measured several batches and find that darker malts go a little lower in pH than predicted and lighter malts go a little higher. Using this experience, I find that I now hit target mash pH usually within +/- 0.1 but never more than 0.2 off and that is plenty good enough. I do not have to measure pH for every batch, but do so every couple of months and if I am changing my process.
What to expect from any meter at this price point:
1) You will need to purchase calibration solutions which run $8 – 10 per 8 oz bottle. I use about an ounce at a time for a calibration and found that once per month is frequently enough. I will pour that ounce out of the battle, calibrate and then pour solution into a secondary bottle (an old thoroughly cleaned spice bottle works great) for reuse and then use that three or four times before discarding and going with fresh solution. While I would not recommended this for critical applications, it works good enough for my needs.Read more ›
Although the device does indeed work, it's not a purchase I'd recommend for the casual user. For the scientist or individual who does a lot of pH testing (say, in a pool), this is probably a five-star product, but for those who just want to take a reading now and then, it gets one star from me, not because it doesn't work (it does) but because the effort simply isn't worth it. For instant, no-fuss soil pH reading, try Luster Leaf 1818 Rapitest Mini 4-in-1 Soil Tester.

Not and accurate instrument. Hard to setup to base line. Has a mind of its own and you don't know if it has gone bat s*** crazy or what?Published 6 months ago by Integrated Elements Unlimited
The first time I used this meter it worked. That's the only time it worked. Big waste of money.Published 16 months ago by Tori Kormanik
Works good only wish it had a hold setting so when you take it out of the water it holds the pH.Published 21 months ago by Randol Sparling
