Introduction
Multifunction environment meter is a 5-in-1 digital multifunctional unit. It measures temperature, %RH, sound level, light level and air velocity. Large, clear display with backlit ensures optimal readability, even in a dark environment. It includes semiconductor sensors for humidity and ambient temperature measurement. The unit automatically shuts down after 15 minutes of inactivity, thus extends battery life.
Applications
Used in factory, hospitals, school, construction, photography, HVAC services, energy audit, research for quality control, environmental monitoring, safety and health.
