• APPLICABLE OCCASION: Widely used in metallurgy, power plants, farms, mines, chemicals, scientific research, treatment, pharmaceuticals, and other fields.
• LCD DISPLAY: Handheld gas detector, equipped with large LCD display, easy to read, 0.1PPM resolution, response time less than 120 seconds, high reliability.
• ACCURATE MEASUREMENT: Using accurate detection technology and sensor chip, the measurement range is 0‑100PPM, and it supports continuous quantitative analysis of concentration.
• GAS DETECTION: Using electrochemical principle sensor, quick response, , its stability, and good repeatability.
• ALARM FUNCTION: Sound and light dual alarm, alarm value can be set, one alarm sound is divided into 80 decibels, which can prompt you to leave the place where the concentration is too high.
