Digital Humidity Sensor Advantages

The SCORPION® 2 Digital Humidity Sensor provides a better way to measure humidity in your oven, proofer, dryer and cooling tunnel. This breakthrough design provides a more accurate and reliable way to measure the absolute moisture content of the thermal environment. The sensor contains a proprietary humidity sampling system with patented Anti-Saturation Technology™ that allows measurements in high temperature and very high dew point processes.

Technical Recommendation
by Bill Hagan

Bill Hagan, technical sales manager for AB Mauri North America, has been profiling ovens, proofers and coolers using the SCORPION®2 Digital Humidity Sensor. Mr. Hagan said that being able to measure humidity throughout the entire baking process, particularly in the oven, allows him to give bakers information that was previously not possible. He further incorporated AB Mauri’s knowledge base to assist and utilize the sensor for use in bread and roll production.

“Data from oven profiling provides absolute humidity measurements verifying steam applications and proper oven exhaust settings. Analysis of proofer data indicates relative humidity throughout the process, allowing the proper settings for optimal proof which yields the desired dough piece texture entering the oven,” Hagan said. “Profiling air-conditioned bread and bun coolers displays relative humidity through the cooler. This data can indicate too much evaporation during the cooling process, thereby drying out finished product prior to being packaged.”

Mr. Hagan recommends the SCORPION®2 Digital Humidity Sensor as an extremely versatile instrument used to document, troubleshoot and improve quality of the complete baking process.
