The Hanna Instruments HI 99151 is a rugged, waterproof, and portable pH/temperature meter designed specifically for the brewing industry. The HI 99151 uses the FC214, a titanium bodied, gel filled pH electrode that features high tempurature glass and an extenable cloth junction. The HI 99151 measures pH from -2.00 to 16.00 pH and temperature from -5.0 to 105.0 ºC (23.0 to 221.0 ºF). Automatic calibration is done at 1 or 2 points with 2 sets of buffers and all readings are automatically compensated for temperature variations. Indicators for stability, battery percentage, and calibration instructions are viewed on the primary display. The HI 99151 uses three 1.5V AAA batteries for an exceptional battery life of 1200 hours of continuous use.

In all grain brewing the enzymes required to convert the starch into sugar are pH sensitive with an optimal pH of 5.2 – 5.6. Different compounds are used to adjust the pH including phosphoric acid, lactic acid and gypsum.

Wort clarity and break formation are also affected by pH. Protein coagulation occurs during wort boiling. The optimum pH is around a pH of 4.9 even though a common boil pH is 5.2. A pH too high will not only inhibit coagulation but also promote browning dues to the interaction of amino acids and reducing sugars.

Hop utilization during the wort boil is affected by pH. As pH increases the solubility of hop resins increase. Unfortunately for hop lovers a high pH also increase the release of tannins resulting in a harsher taste. Higher pH also favors microbial activity.

Description
The HI 99151 beer pH meter uses the titanium body FC214 amplified pH electrode with built in temperature sensor. The amplified electrode provides a fast stable response that is immune to electrical noise due to humidity. The body of the electrode is made from titanium, which provides an unbreakable structure that allows the transfer of heat to the internal temperature sensor for rapid temperature compensation.

An integral part of any pH electrode is the reference junction. The reference junction is a part of the electrode that allows for the flow of ions located in the reference cell into the sample being measured. It is vital that this flow occurs in order to complete an electrical circuit. Any clogging of the reference junction will prevent the circuit from being completed and will result in readings that are erratic and/or constantly drifting. A typical pH electrode has a junction made of ceramic material. This ceramic material can be easily clogged by samples, such as mash with a high solids content and wort that is viscous. With the Hanna Instruments cloth junction it is possible to clear the clog by simply extracting 1/8” of the junction from the electrode. This exposes a new portion resulting in a renewed junction.
