A commercial brewery grade, portable pH meter that is designed specifically for beer.
The Hanna Instruments HI99151 is a durable, waterproof, and portable pH and temperature meter designed specifically for beer analysis. Automatic calibration is performed at one or two points with two sets of buffers. All calibration and measurement readings are automatically compensated for temperature variations.
The HI99151 uses the FC214D titanium body, amplified pH electrode that offers numerous features that improve pH testing for beer analysis. The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and calibration instructions.
Waterproof - The HI99151 is a waterproof meter rated IP67 for immersion in up to one meter of water for 30 minutes.
Automatic Calibration - One or two-point calibration is automatic to two selectable buffer sets.
Automatic Temperature Compensation – An integrated temperature sensor allows for automatic temperature compensation of pH measurements.
Multi-Level LCD Display - The split-level LCD displays both pH and temperature readings, along with indicators for reading stability, battery percentage, and calibration instructions.
On-Screen Tutorial - Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration.
Battery Error Prevention System - The meter will automatically shut off if there isn’t enough power to obtain an accurate measurement.
Battery Life Indicator - The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.
The specialised electrode offers numerous features that improve pH testing in beer. An integrated temperature sensor allows for temperature compensated pH measurements without the need for a separate temperature probe. The probe’s spheric sensing tip has a wide surface area for measurement in aqueous solutions.
A typical pH electrode has a junction made of cloth material. This cloth material can be easily clogged by samples such as mash, which has a high solids content, or wort, which is viscous. With the cloth junction of the FC214D it is possible to clear any obstruction by simply extracting 1/8” of the junction from the electrode. This exposes a new, renewed portion.
Titanium construction provides an unbreakable structure and allows the transfer of heat to the internal temperature sensor for rapid temperature compensation.
When readings are erratic or unstable, a small portion (1/8”) of the extendable cloth junction is pulled out to expose a fresh new surface.
BUILT-IN TEMPERATURE SENSOR
Error in calibration and measurement are eliminated with the Automatic Temperature Compensation provided by the integrated temperature sensor.
