Pure carbon monoxide (CO) is colorless, odorless, and non-irritant gas: molecular weight: 28. 01; Density: 1. 250g/ l; freezing point: - 207C; boiling point: - 190C. Its solubility in water is quite low, but it dissolves instantly in ammonia water. Air mixed explosion limit is between 12. 5% and 74%. After entering human body, carbon monoxide will combine with hemoglobin in blood, making the hemoglobin not able to combine with oxygen, which causes oxygen deficit to organism organization, leading to death from suffocation. Therefore, carbon monoxide is toxic, and is colorless, odorless, and tasteless, which is easy to be ignored and thus causing poisoning. The carbon monoxide detector can detect the concentration of carbon monoxide gas, and observe the value of carbon monoxide gas concentration at any time. It has a very clear large LCD screen, sound and light alarm prompts, to ensure that dangerous gases can be detected under very unfavorable working environments and prompt operators to prevent them in time. It is widely used in petroleum, chemical, coal, metallurgy, papermaking, fire fighting, municipal administration, telecommunications, food, textile and other industries. 1.

Features 1. Split Type Design: the separation of the measurement part and reading part with retractable spring can avoid the influence of strong light on the naked eye. 2. Wide Measurement Range: 0-200000 lux and 0Fc ~ 20000Fc with switchable units of Lux / Fc and temperature units of degree C / degree F. 3. Large illumination probe effectively increases the measurement area with better processing efficiency in higher or narrower measurement environment. 4. 2 recording modes: automatic storage of illumination data (up to 2000 groups) and manual storage (up to 60 groups). 5. MAX / MIN / Difference Value / Data Hold functions, high accuracy with automatic range and quick response. 6. Large and clear LCD display with backlight for easy reading. 7. Low battery indication & auto power off, energy saving. 8. Widely used for monitoring light intensity in homes, laboratories, office, schools, indoor farming, etc. Specification 1. Material: Plastic 2. Measuring Range: 0 Lux ~ 200,000 Lux, 0Fc ~ 20000Fc 3. Power Supply: 3 x 1.5V AAA Batteries (Not Included)
