Continuous air data
Track VOCs and harmful gases across time and location. Baselines and event histories reveal patterns that periodic inspection can easily miss.
Environmental monitoring
Environmental
Build a continuous, connected view of air quality, toxic gases and emission sources across sites and communities. Combine persistent monitoring with mobile investigation so environmental change can be located, understood and documented.
Mission focus
Turn measurements into evidence and action.
Environmental investigation needs both persistent context and field verification. GD624 monitors configured toxic, hazardous and flammable gases across multiple channels, while GM602 provides fixed online monitoring for VOCs and selected toxic industrial chemicals. VP200 helps field teams follow VOC response and concentration gradients, and RM1200 extends X-ray and gamma dose monitoring to fixed, vehicle or unmanned platforms.
The methods remain distinct: a PID survey can locate a hotspot but does not by itself identify every compound, and radiation measurements address a different hazard class. Time, location, calibration and intervention records turn these complementary readings into defensible environmental evidence.
Source investigation
Use portable sensing to narrow and verify emission sources. Mobile readings connect a network alarm with actual conditions at suspected hotspots.
Trend evidence
Compare events, baselines and interventions with traceable data. Teams can demonstrate whether conditions returned to normal and where further work is needed.
Operational sequence
Field workflow
A clear sequence connects early indication, field confirmation and a defensible decision - giving every team a shared understanding of what happens next.
Sense
Fixed monitoring establishes continuous coverage. Networked points provide a time-and-place context for unusual readings and changing conditions.
Investigate
Mobile instruments test hotspots and likely sources. Teams can follow the concentration gradient and verify conditions closer to the suspected origin.
Report
Connected records support analysis and communication. The final account can link the alert, investigation, intervention and measured outcome.
Selected solutions
The right tools for the task.
01
GD624
02GD624 is an environmental chemical monitoring system that detects up to 24 gases at once using multi-sensor, multi-channel direct detection, integrating optical ionization, electrochemical and infrared sensors. It is built for real-time monitoring of toxic, hazardous and flammable gases in emergency response, firefighting and industrial environments.
GM602
03GM602 is an online gas environment monitoring system for volatile organic compounds and toxic industrial chemicals. It provides real-time monitoring of air pollutants such as benzene, aldehydes and ketones in enclosed spaces, petrochemical facilities and construction sites.
VP200
04VP200 is a handheld photoionization gas detector that measures trace, ppb-level concentrations of volatile organic compounds and alarms when thresholds are exceeded. It detects over 200 VOCs and also alarms for inorganic toxic gases including ammonia, phosphine, arsine and hydrogen sulfide.
RM1200
A rugged, wide-range X-ray and gamma radiation detection module for unmanned, mobile, vehicle-mounted and fixed monitoring systems. RM1200 measures ambient dose rate and accumulated dose, responds in as little as 2 seconds at higher dose rates, and maintains an overload alarm beyond its measurement range.
