BIOLOGICS
Check4-COVID™
The fast, accurate and affordable COVID self-test for smartphones
Check4-COVID™ is a fast, accurate and affordable molecular test for COVID-19. Results are displayed within minutes on a smartphone app, which automatically fulfills reporting requirements.
FOOD SAFETY
& SUSTAINABILITY
Check4-FRESH™
A real-time monitoring system that ensures a safe and sustainable food supply chain
Check4-FRESH™ is a widely deployed sensor system for the food supply chain from farm to consumer. Real-time monitoring of food spoilage and contamination levels significantly reduces food waste and foodborne illness. Sensors that detect food spoilage generate alerts in real-time to operations control centers and smart devices for automated optimization of the food chain.
INFRASTRUCTURE
& ENVIRONMENTAL MONITORING
Check4-LEAKS™
A leak-detection, sensor system that generates alerts when safety thresholds are exceeded
Check4-LEAKS™ is a widely deployable sensor system for continuous monitoring of hazardous leaks, emitted in air or water. The system dramatically improves safety, regulatory compliance, operational efficiency and environmental sustainability.
NATIONAL SECURITY
Check4-THREATS™
A forward-deployed sensor system for real-time detection and reporting of national security threats
Check4-THREATS™ is a forward-deployed sensor system for real-time monitoring of cargo and passengers for security threats. Threats include explosives, drugs, chemicals and biological, radiological and nuclear material.
