H3 · PORTABLE FUEL CELL BREATHALYZER
H3 Portable Breathalyzer with Fuel Cell Sensor
H3 is a portable breathalyzer developed for brands and distributors looking for a lightweight fuel cell alcohol tester with expanded test history and optional Bluetooth connectivity. It combines a compact housing with a UK Dart sensor platform.

WHY THIS MODEL
Designed Around a Clear Product Need
An everyday portable format with a UK Dart fuel cell sensor.
Portable at approximately 29g
With a specified weight of about 29g, H3 offers a genuinely lightweight handheld form for portable breath alcohol testing.
UK Dart fuel cell sensor
The sensor origin is a clear technical difference from semiconductor breathalyzers; actual accuracy depends on calibration and testing conditions.
More room for test history
H3 stores up to 2,000 records, while Bluetooth can be specified as an option when connected functionality is needed.

Product design and configuration may vary according to the approved production specification.
HARDWARE & USER EXPERIENCE
Portable Should Mean Easy to Carry and Easy to Use
A portable breathalyzer should suit the user’s routine, not introduce unnecessary steps. H3 uses a compact IPS display and a lightweight housing while keeping a useful test-history capacity.
The optional Bluetooth configuration is important for OEM procurement: buyers should confirm whether their chosen build needs wireless support instead of assuming it is standard on every H3.
- Approximately 29g specified weight
- UK Dart fuel cell sensor
- 1.2-inch IPS display
- 2,000 recorded tests
