M-Log ELO009 by LSI Lastem is a versatile, compact data logger for professional environmental monitoring. Designed for thermal comfort assessment, HVAC testing, and building efficiency analysis, it features 4 analog inputs, 2 RS232 ports, and auto-sensor recognition. With ultra-low power consumption, 8 MB memory, and programmable acquisition rates (1s-12h), it supports 50+ derived quantities like WBGT, PMV indices, and SARS-CoV-2 decay modeling. Ideal for indoor air quality, ventilation studies, and industrial applications, its rugged design includes a display/keyboard interface and Modbus-RTU compatibility for seamless integration.
Precision Environmental Monitoring Simplified
The M-Log ELO009 data logger delivers laboratory-grade accuracy in a compact, field-deployable package. Engineered for thermal comfort assessments (ISO 7730), HVAC performance verification, and building energy audits, it dynamically calculates 50+ derived parameters including WBGT indices, radiant asymmetry, and air changes. Its dual RS232 ports support hot-wire anemometers and Modbus-RTU sensors, making it indispensable for occupational health studies and indoor air quality diagnostics.
Intelligent Data Processing & Connectivity
Automate complex environmental analyses with the logger's integrated statistical engine, processing instantaneous values into min/max/avg, wind dynamics, and totals. The 8 MB flash memory stores weeks of continuous data, while RS232/USB/Ethernet interfaces enable real-time monitoring via LSI LASTEM's 3DOM software. The onboard display and keyboard provide immediate field access to critical metrics from SARS-CoV-2 decay rates to daylight factors.
