Compact MX2502 Underwater Logger Records PAR, Temperature, Tilt Precisely
The MX2502 data logger from BMC Solutions introduces a compact addition to the HOBO-MX series, engineered for accurate underwater recordings by simultaneously capturing photosynthetically active radiation (PAR), temperature, and tilt angle. Its integrated water detection ensures clear separation of underwater measurements from dry-test data, while its slim housing allows flexible mounting on sensor arrays, dive rigs, or submersible platforms. Durability, compactness, and multi-parameter logging optimize marine and freshwater research efficiency.
LI-192 Quantum Sensor Measures PAR 400 to 700 nm
The MX2502 data logger employs an integrated LI-192 quantum sensor to detect light wavelengths ranging from 400 to 700 nm. This configuration ensures precise measurement of photosynthetically active radiation (PAR) with exceptional long-term stability. Factory calibration embedded within the sensor guarantees consistent performance over extended deployments without necessitating frequent recalibrations. Users benefit from reliable irradiance data, enabling accurate assessments of underwater light environments for aquatic research, monitoring, and ecological studies.
Compact Logger Records PAR, Temperature, Tilt With Water Detection
In addition to its PAR channel, the logger records temperature and tilt angle, enabling comprehensive environmental monitoring. The tilt sensor logs orientation details to track device positioning and alignment underwater accurately, providing essential context for measurement. An integrated water detection mechanism automatically distinguishes between submerged and aerial conditions, filtering out non-relevant readings. This ensures that only pertinent data logs are stored, maintaining high data quality and minimizing time on post-processing.
MX2502 Logger Withstands 30m Water Depth, Ensures Corrosion-Free Operation
The MX2502 enclosure carries an IP68 rating, ensuring continuous operation in freshwater and saltwater environments. Designed to withstand pressures at depths up to thirty meters, its durable housing safeguards electronics from corrosion and prevents moisture intrusion under demanding conditions. This level of protection enables reliable long-term deployment in diverse aquatic monitoring applications, including limnology, oceanography, aquaculture, and habitat restoration projects. It maintains operational integrity in lakes, coastal zones, and streams.
Bluetooth LE powers wireless HOBOconnect configuration and data retrieval
By leveraging Bluetooth Low Energy connectivity through the HOBOconnect App, users can configure recording parameters and retrieve logged data wirelessly. Measurement intervals are adjustable, real-time sensor readings can be monitored on a mobile device, and log files can be downloaded in the field without opening the enclosure or connecting a laptop. This streamlined process effectively minimizes handling time, enhances deployment flexibility, and significantly improves operational efficiency during remote monitoring campaigns.
Automatically upload sensor data to LI-COR Cloud for analysis
Users can optionally enable automatic upload of collected measurement data to the LI-COR Cloud, where a suite of advanced analysis and visualization tools is available. This data transfer streamlines documentation and integration for extended monitoring campaigns by consolidating results, reducing intervention, and maintaining data integrity. The cloud connection fosters collaboration across teams by providing shared access to organized datasets and simplifies reporting workflows through customizable dashboards and automated summary generation.
MX2502 Logger Powers Aquatic Light Monitoring Across Diverse Research
The MX2502 is frequently employed in limnological research to measure photosynthetically active radiation profiles in lakes and reservoirs, providing critical data for primary production and trophic status assessments. In oceanography, it enables detailed studies of light attenuation and ecosystem metabolism across varying depths. The device also supports aquaculture monitoring to optimize light conditions for cultivated species and facilitates restoration project evaluations by delivering precise, reproducible measurements of underwater light availability.
The MX2502 underwater data logger combines compact form and IP68-rated durability to withstand depths of up to 30 metres in saltwater environments. It integrates a calibrated LI-192 quantum sensor for precise PAR measurements alongside temperature and tilt angle logging. Automatic water detection ensures valid underwater data capture. Bluetooth Low Energy enables wireless field configuration and data retrieval via the HOBOconnect app, while optional LI-COR Cloud integration streamlines long-term data management.
