Tinytag data loggers support energy efficiency applications by accurately monitoring power usage, CO2, temperature and humidity locally or throughout a building. This helps identify where steps can be taken to improve energy efficiency, maximise cost savings, and ensure the occupants’ wellbeing. The range includes the Energy Logger, a portable, non-invasive device for monitoring single/three phase power usage: this is useful for monitoring energy consumption in line with ESOS and other energy management requirements. Temperature, humidity and CO2 loggers help validate whether heating and ventilation systems are working correctly, and record conditions to comply with H&S regulations. Tinytags are manufactured in the UK.
