Electrochemical Breathalyzer Sensor for Alcohol Test Meter


  • Product Code: FS00703
  • Availability: In Stock
  • Ex Tax: $22.00

The FS00703 alcohol sensor is based on high-sensitivity electrochemical principles and offers a fast response time without the need for waiting. It comes pre-calibrated at the factory, eliminating the requirement for professional equipment for secondary calibration. The sensor can operate in two output modes: 0-500ppm (gas alcohol concentration) or 0-500mg/100ml (blood alcohol concentration), making it particularly suitable for applications such as drinking and driving detection, pre-employment screening, and other scenarios. This simplifies customer development and usage.
