INTELLIGENT DESIGN FEATURES
Probe Condition Indicator
An on-screen visual indicator confirms your probe is performing optimally, eliminating guesswork and ensuring reliable measurements every time.
Smart Battery Management
Get 1,200 hours of continuous use from the included AAA batteries. A low battery warning appears when power drops below 10%, and the meter automatically shuts down before low voltage can compromise your readings—protecting you from inaccurate results.
Customizable Auto Shut-off
Set auto-off to 8 minutes, 60 minutes, or disable it entirely for continuous operation. This intelligent feature extends battery life and prevents energy waste if you accidentally leave the meter on.
IP67 Waterproof & Dustproof
Engineered to survive the knocks, drops, and spills of real brewery environments. The IP67-rated body provides complete protection against dust and water intrusion from any direction—ensuring top performance in any condition.
Ergonomic Portable Design
Fits comfortably in your hand for on-the-go testing throughout the brewery. The multilevel LCD display delivers at-a-glance pH and temperature readings from any viewing angle, while dual-button operation streamlines testing for any user.
Quick Connect Probe System
The Quick Connect DIN connector makes probe attachment and removal simple and effortless. The rubber-coated seal provides a watertight connection without twisting or threading.
FC2143 PROBE: PRECISION-ENGINEERED FOR BREWING
Your measurements demand detailed attention—so should your electrode. The HI99151 features a replaceable FC2143 probe specifically designed to measure pH in beer, mash, and wort with unmatched reliability.
Flat Glass Tip
The flat glass sensor tip is easy to clean and prevents solids in mash and wort samples from collecting on the sensor—reducing maintenance and ensuring consistent accuracy.
Cloth Junction Technology
The FC2143 features a cloth or fiber wick junction that provides a significantly larger surface area than standard ceramic junctions. This advanced design excels when measuring pH in liquid samples with higher solids content—exactly what you encounter in mash, wort, and beer.
Virtually Unbreakable Titanium Body
The titanium probe body is virtually indestructible, protecting your investment from accidental drops and impacts. This makes it ideal for the rough-and-tumble environment of active brewing operations.
COMPLETE TESTING KIT INCLUDED
We believe buying a meter should be simple. Your HI99151 Beer pH Meter arrives equipped with everything you need for successful testing right out of the box—no additional purchases required.
pH 4.01 & 7.01 Calibration Buffer Sachets
Accurate calibration requires the correct buffers. We include starter buffers to get you testing immediately. Each single-use sachet is individually sealed so you use fresh buffer every time you calibrate.
Specialized Cleaning Solution for Brewing (2 Sachets)
Your Beer pH Meter includes HI700682 cleaning solution specifically engineered to remove yeast and sugar buildup from your electrode. This concentrated detergent blend cleans quickly and effectively, keeping your meter in optimum condition for accurate, reliable readings.
Additional Included Accessories
- 100 mL beaker for calibration and testing
- Three 1.5V AAA alkaline batteries
