Hanna pH Meter for Beer Analysis HI99151

The Hanna Instruments HI99151 is a rugged, waterproof, and portable pH/temperature meter designed specifically for the brewing industry. The HI99151 uses the FC214D, a titanium bodied, gel filled pH electrode that features high temperature glass and an extendable cloth junction. The HI99151 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 one or two points and all readings are automatically compensated for temperature variations. Indicators for stability, battery percentage, and calibration instructions are viewed on the primary display. The HI99151 uses three 1.5V AAA batteries for an exceptional battery life of 1200 hours of continuous use.

In the brewing process, the enzymes required to convert the starch into sugar are pH-sensitive with an optimal pH range between 5.2 pH and 5.6 pH. 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, where the optimum pH is around 4.9 even though a common boil pH is 5.2. A pH that is too high will not only inhibit coagulation but also promote browning due to the interaction of amino acids and reducing sugars.

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

The HI99151 beer pH meter uses the amplified, titanium-bodied FC214D 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, which has a high solids content, or wort, which 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.

Extendable cloth junction

Clear a clogged junction by simply extracting 1/8” of the cloth junction from the electrode. This exposes a new portion, resulting in a renewed junction.

Unbreakable titanium body

Titanium construction provides an unbreakable structure and allows the transfer of heat to the internal temperature sensor for rapid temperature compensation.

Maintenance free, gel filled electrode

No fill solution required.
