HSCA2000 On site Printed Alcohol DetectorIt is a highly reliable, high-precision, respiratory alcohol detector certified by the US DOT. The core components of CA2000 adopt a new high-tech micro variable oxide semiconductor, which can accurately detect the alcohol content of gases without interference from non-alcoholic gases such as smoke, cola, coffee, etc. The HSCA2000 is compact, lightweight, and easy to operate, making it a great choice for portable applications.

HSCA2000 On site Printed Alcohol DetectorMain technical parameters:
Display: Three digit display (x.xx% BAC/BRAC)
Detection range: 0.00-0.40% BAC or 0.00-2.00% BAC
Detection accuracy: ± 0.01% (0.01BAC) or ± 0.05mg/liter (0.50 BRAC)
Recovery time: 30 seconds 5) Preheating time: 20 seconds
Sensing time: 5 seconds
Extremely low power consumption: A 9-volt square battery can detect more than 300 times.
Bright characters: Red LED displays data, clearly visible at night.
Sound alarm: Alcohol content exceeds *, buzzer automatically sounds an alarm

Operation method:
Press the power switch to perform internal self check and preheating of the instrument, displaying a countdown from 200 to 000 for 20 seconds;
The countdown ends with a sound prompt and the green light turns on, indicating that the instrument is functioning properly and testing can begin;
Aim at the air inlet and blow air for about 5 seconds. If alcohol is detected, the buzzer will sound and the red and green lights will flash simultaneously. In 4 seconds, the concentration data will be displayed. If the concentration is between 0.00 and 0.05, only the green light will flash; If it is greater than or equal to 0.05, only the red light will flash and accompanied by a rapid sound alarm. After holding the concentration data for 15 seconds, the instrument display changes to OFF;
If no alcohol is detected from the blowing air or no detection is performed within 30 seconds after turning on the device, the instrument display will change from 000 to OFF;
When the instrument displays OFF, it must be turned off to restart the measurement;
precautions:
◆ Do not blow smoke into the air vent. Liquid cannot enter the pores. Do not block the air outlet;
The yellow light indicates that the power supply voltage is low and the battery needs to be replaced;
