About AQ Sense
AQ Sense GmbH (AQS), headquartered in Ebenhausen near Munich, develops and manufactures solutions for gas detection and gas monitoring. The portfolio covers the complete signal chain: from sensor chips, smart gas sensors and gas measurement modules to smart gas devices, fixed-installation gas detectors, controllers and online monitoring systems. The products measure toxic gases, flammable gases, oxygen, CO2 and VOCs using, among others, solid polymer electrochemical sensor technology, achieving PPB-level detection at operating temperatures from −40 °C to +55 °C. The core team developers have more than 20 years of experience in gas detection technology, with development teams in Germany and China. Customers come from industrial production safety (petrochemicals, steel, fertilizers, power plants), environmental and outdoor air monitoring, mining, agriculture and livestock farming, medicine, laboratory environments and the food industry. Calibration and performance testing are carried out with an intelligent valve test calibration system from Germany; according to the company, all deliveries undergo 100 % factory inspection.

Sensors & Measurement Technology
Solid polymer electrochemical sensor technology
Detects gas concentrations from 1 ppb or 1 µg/m³ without warm-up time and without zero-point drift, lifetime over 3 years.
Explosion-proof housing
Fixed gas detectors for -40 °C to +50 °C with 4–20 mA and RS485 output for hazardous areas.
Digital signal modules
Gas measurement modules with UART (TTL 3.3 V) or I²C output, low power consumption for battery and IoT applications.
