Here's how some of our customers use this product...

Energy Auditing

The Background: Our customer is an energy management company currently performing an energy audit on a large commercial building. As part of this audit, they require a number of data loggers for collecting information regarding temperature, humidity and lighting.

The Problem: As the customer requires the logging of different parameters in several locations throughout the building, they seek an efficient solution.

The Solution: We suggested the HOBO U12 Series data logger which provides flexibility for monitoring up to 4 channels of energy and environmental data with a single, compact logger. The U12 Series supports a wide range of measurements including temperature, relative humidity, dew point, 4-20mA, AC current, AC voltage, air velocity, carbon dioxide, compressed air flow, DC current, DC voltage, gauge pressure, kilowatts, light intensity, and VOC. Some measurements require additional sensors. The U12 Series provides the data to show where energy is being used and helps inform where saving energy is possible.
