CTH1000 mine explosion determination of carbon monoxide mines determination of carbon monoxide Main features: CTH1000 type carbon monoxide detector, using long-life electrochemical sensor and micro-power single-chip control bears, four LCD display, the instrument is not only sound and light alarm, 0:00 tracking, automatic backlight, undervoltage alarm function, but also has accurate and reliable, long life, small size, light weight, simple operation, easy maintenance. This instrument is widely used in the presence of explosive mixtures of flammable gases in the work environment continuously detect the concentration of carbon monoxide gas. Determination of carbon monoxide works: the instrument works: electrochemical sensor by diffusion in the environment directly, reaction with carbon monoxide gas electrical signal proportional to the concentration of the measured gas, filtered and amplified by the signal conditioning circuitry into the microcontroller after data processed and displayed on the LCD screen of carbon monoxide gas concentration value, when the carbon monoxide concentration is higher than the alarm set point, the instrument audible alarm signal. Main Specifications: Measuring range :0-1000PPM error: ≤ ± 10% true value sensor life: more than 3 years Response time: ≤ 35S Display: 4-digit LCD Alarm: Intermittent sound and light alarm, alarm point continuously adjustable shape Size: 94 * 52 * 28MM Explosion-proof way: Exib I celebrate Jining Branch Mining Equipment Co., Ltd.
