Tips for alcohol measurements

Using a comprehensive sensor directly for occasional alcohol (ethanol) detection? Calibration without paying attention to details leads to inaccurate data and shortened sensor life? In fact, you can avoid these problems by grasping the core specifications! This super practical guide helps you accurately handle sensor selection and calibration for alcohol measurement!

I. Core Principle of Sensor Selection

For ethanol (alcohol) measurements only, a special alcohol sensor is recommended as the priority —— it can maximize detection accuracy and avoid cross-interference.

II. Calibration Specifications for Comprehensive Measurement Scenarios (Applicable for Occasional Alcohol Detection)

If a comprehensive sensor is needed for both alcohol detection and other gas measurements, calibrate promptly in accordance with the following standards —— no step can be skipped!

1. Core Calibration Parameters

◦ Calibration Gas: Ethanol gas concentration ＜ 100 ppm

◦ Gas Flow Rate: 300 ml/min

◦ Ventilation Duration: Maximum 3 minutes of continuous venting

1. Key Operation Taboo

◦ Avoid directing the flow of gas towards the air inlet

1. Correct Operation Method

◦ Use a side air inlet positioned at a 90-degree angle to the air inlet

◦ Core Purpose: Ensure the sensor operates in a diffuse measurement state, thereby avoiding flow shocks

III. Special Application Note

If your usage scenario is a special working condition (such as high temperature, high humidity, multi-gas mixed environment), please consult us separately to obtain a customized solution.

Warm Reminder

1. A special alcohol sensor is the "optimal solution" for alcohol detection, with much higher accuracy and stability than comprehensive sensors;

2. For comprehensive sensors calibrating alcohol, parameter deviations and improper operations will directly lead to distorted detection results and even sensor damage;

3. All operations must be combined with the sensor manual. After calibration, it is recommended to perform a blank test to confirm the equipment is normal.
