Multifunction Environment Meter LB-10MEM Catalog

Multifunction environment meter LB-10MEM 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.
