About HOBO

HOBO is a brand of data loggers and environmental monitoring instruments manufactured by Onset Computer Corporation, a company based in Bourne, Massachusetts, USA. Onset has been producing data loggers since the early 1980s, and the HOBO line is widely recognized in industrial, research, and facility management applications for its reliability and range of measurement capabilities. The product families available through 3G Electric include temperature and humidity data loggers, temperature/light data loggers, soil moisture loggers, pressure and temperature data loggers, analog data loggers, and accessories such as light pipes. These devices are used for monitoring environmental conditions in settings such as HVAC system verification, cold chain logistics, building energy audits, agricultural research, and industrial process control. HOBO data loggers are designed to meet specific measurement needs, with models offering wireless Bluetooth communication, USB interface, or standalone operation. Many units are waterproof to depths such as 30 meters (e.g., MX2202) and operate over temperature ranges from -40°F to 158°F (-40°C to 70°C) depending on the model. Relative humidity measurement spans 0% to 95% RH on certain models. The loggers are built with features like LCD displays, hook-and-loop strips for mounting, and command strips for secure attachment. Some models include auto-calibration of ON/OFF thresholds to ensure reliable readings. The MX series supports Bluetooth communication for wireless data access via mobile devices, while UX series models typically use USB connectivity for direct download to a computer. Software is available separately for data analysis and configuration. 3G Electric stocks 16 SKUs of HOBO products, providing datasheets and logistics support for global procurement. The brand is known for research-grade measurements at accessible price points, with compliance to CE and RoHS standards on select accessories. Applications span from indoor air quality monitoring to outdoor environmental studies, with the ability to log data over extended periods using battery power. The product range includes both single-parameter and multi-parameter loggers, allowing engineers and maintenance managers to select the appropriate device for specific monitoring tasks without overspecifying. HOBO loggers are commonly used in facilities management to track temperature and humidity in server rooms, warehouses, and cleanrooms, as well as in field research for soil moisture and light intensity measurements. The brand's long history in the data logging industry means its products are supported by a mature ecosystem of software and accessories, though 3G Electric does not provide software or calibration services directly. The selection available through 3G Electric covers entry-level USB loggers to advanced wireless models, all sourced from Onset's standard production lines.
