Onset Computer Corporation designs and manufactures the HOBO family of data loggers — compact, battery-powered instruments for temperature, humidity, water level, and general environmental monitoring, along with the HOBOlink cloud platform for remote data access. Metronix is listed on Onset's official distributor network as the Philippine channel for HOBO products, supplying loggers for climate research, agriculture, building science, and water monitoring applications nationwide. Onset was acquired by LI-COR Environmental in April 2024 and now operates as part of the LI-COR Environmental portfolio (see LI-COR below), though the HOBO brand and product line continue under the Onset name.

SOMMER Messtechnik, based in Koblach, Austria, has specialized in hydrographic and geotechnical measurement instruments for over 30 years. Its RQ-30 series non-contact radar sensors measure river and canal discharge, velocity, and water level without touching the water surface — the same sensor line and product description Metronix markets in the Philippines as its Non-Contact Discharge Radar RQ-30+ offering for flood monitoring and irrigation management.

Telegrafia designs and manufactures electronic sirens, public-address and evacuation systems, monitoring stations, and the Vektra control-centre software used to arm, schedule, and trigger warning networks. Its systems are deployed in more than ninety countries for flood, tsunami, industrial, and civil-defense alerting — the hardware behind Metronix's public warning system installations in the Philippines.

KISTERS, based in Aachen, Germany, supplies both hardware and software for water and environmental monitoring. Its HyQuant series uses 60 GHz radar-on-chip technology to measure water level, velocity, and discharge without contacting the water, and its WISKI platform is an industry-standard system for importing, validating, and reporting hydrological, meteorological, and water-quality time-series data at network scale.

JDC Electronic, based in Yverdon-les-Bains, Switzerland, designs and manufactures the Skywatch line of handheld anemometers, portable and fixed weather stations, and smartphone-connected environmental sensors, alongside connected sensor networks for precision agriculture. Its instruments are used across emergency response, construction, agriculture, and scientific research.

E2S Warning Signals manufactures audible and visual signaling devices for hazardous areas, fire and industrial sites, and wide-area/mass-notification alerting, with ATEX, IECEx, UL, and DNV certification. Its wide-area electronic and motor-driven sirens are built for exactly the flood, tsunami, and civil-defense warning applications Metronix deploys for, complementing its Telegrafia siren line with hazardous-area-rated options.

Solinst manufactures water level meters, the Levelogger series of submersible water level/temperature dataloggers, Barologgers for barometric compensation, groundwater samplers, and multilevel well-monitoring systems. Its instruments are the industry standard for hydrogeologists and environmental consultants, giving Metronix a dedicated groundwater and borehole monitoring line alongside its surface-water radar sensors.

LI-COR Environmental, based in Lincoln, Nebraska, manufactures gas analyzers and eddy covariance systems used to measure CO2, methane, and water-vapor flux between ecosystems and the atmosphere — instrumentation used in climate research, carbon accounting, and agricultural monitoring. In April 2024, LI-COR Environmental acquired Onset Computer Corporation (HOBO), making it the parent company behind Metronix's existing HOBO data-logger line as well as a distinct source for greenhouse-gas and flux-monitoring instruments.

Aeron Systems, based in Pune, India, builds wireless data loggers and meteorological stations used to monitor solar power plants and agricultural sites — its weather monitoring network reportedly covers more than 32 GW of solar PV capacity worldwide. The company also manufactures inertial navigation systems for defense and aerospace, a separate product line outside Metronix's scope of distribution.

Senix Corporation, now part of BinMaster Sensors and Technologies, manufactures the ToughSonic line of rugged, IP68-rated ultrasonic sensors for non-contact distance and level measurement, with ranges up to 15 m. Ultrasonic sensing gives Metronix a lower-cost, non-radar alternative for water level and flood-detection installations where budget or mounting constraints rule out radar.

Observator Group, established in 1924 in the Netherlands, supplies meteorological and hydrological instruments and complete systems, including its Airotec Automated Weather Observing System (AWOS) product line used at airports for aviation safety. This gives Metronix an aviation-grade weather observing option alongside its general-purpose AWS line for airport and airstrip clients.

AQMesh air monitoring equipment measures up to 6 gases, particulate matter (dust), wind speed and direction, noise, and offers multiple power options including solar. With our customisation you can choose the specific gases for your project, keeping costs low by only paying for what you need. Known for its reliability and versatility, AQMesh monitors were the first environmental monitoring equipment suppliers for small sensors and continue to lead industrial air quality monitoring innovation today. With real time data and on-going technical support, our team will ensure your air quality monitoring is an easy operation.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), under the Department of Science and Technology (DOST), sets the certification standard that Metronix's automatic weather stations are built to meet, and has engaged Metronix directly through public procurement for hydromet and weather-monitoring equipment. This relationship underpins Metronix's credibility in government-grade environmental monitoring.
