Product Description

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.

4.0 out of 5 stars Nice, seems accurate, January 22, 2010

This is the first ph tester that I have ever used. Works good, seems accurate. I did have to calibrate it by one point when I took it out of the box. Be careful of the top where the on/off switch is at. I accidentally popped it off and the wire connecting to the battery pack broke, a little bit of soldering took care of that. The only way you can get the top back in place is to remove the screw and slide the inside out from the case. The instructions fail to mention that point.

3.0 out of 5 stars A real pain to use, April 15, 2010

I bought this Hanna pH tester because I wanted to easily test my soil pH without having to mix it into a set of little vials, add solutions, and then analyze the color. Well, I should have done more research, because this pH tester requires so many solutions -- storage solution, buffer solution, and solutions that are high or low pH-specific -- that it becomes a major production. If the solutions came with the unit, it wouldn't have been so bad, but tracking down all the necessary supplies ended up being more expensive than the tester itself.

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.
