K1 · MINI FUEL CELL BREATHALYZER
K1 Mini Breathalyzer with Fuel Cell Sensor
The Airsense K1 is a mini breathalyzer built around a compact electrochemical fuel cell sensor. With an easy-to-carry body, zero-second specified warm-up and standalone operation, it is a practical option for brands developing a simple personal alcohol tester.
WHY THIS MODEL
Designed Around a Clear Product Need
Pocket-sized form. Straightforward breath alcohol testing.
Truly compact hardware
At approximately 61 × 37 × 19mm, K1 is designed for buyers who want a small breath alcohol tester rather than a bulky instrument.
Fuel cell sensing
The electrochemical fuel cell platform differentiates K1 from a typical mini semiconductor alcohol tester. Product performance depends on proper use and calibration.
Standalone by design
K1 operates without a phone app or Bluetooth connection. That helps keep the product experience direct for buyers who prefer a self-contained device.
Product design and configuration may vary according to the approved production specification.
HARDWARE & USER EXPERIENCE
A Small Breathalyzer Designed for Everyday Carry
K1 is a natural fit for a compact personal breathalyzer lineup. It pairs a pocket-friendly housing with an IPS display and retains up to 200 test records. There is no app setup step or phone pairing workflow.
For importers and brand owners, this means a product story focused on compactness, familiar operation and sensor technology—not unnecessary connectivity claims.
