The compact and versatile data logger


M-Log is a line of compact data loggers for environmental monitoring, suitable for portable indoor applications. Small and flexible, but also powerful and reliablem M-Log can be used in virtually unlimited environmental applications.

Typically M-Log (ELO009) is used on a portable tripod fot Thermal Environmental measurements for the assessment of thermal comfort and stress, air quality, ventilation measurements, thermo-hygrometric measurements for assessing the energy efficientcy of buildings and HVAC tests.

The ELO008 model, having terminal block input, is more suitable for measurements always in the field of environmental monitoring, but in industrial situations. Typically, thanks to the Modbus-RTU protocol (Master/Slave), it is used as an interface between sensors and systems such as PLCs, as well as storing processed values and sending instantaneous values to PC.
