Heng Aode answers the test methods and features of the carbon monoxide detector Pumped carbon monoxide detector TEST-4 features Carbon monoxide (CO) is a colorless, odorless, non-irritating gas. The molecular weight is 28.01, the density is 1.250 g/l, the freezing point is -207 ° C, and the boiling point is -190 ° C. It has a very low solubility in water but is easily soluble in ammonia. The air mixing explosion limit is 12.5% ​​to 74%. After entering the human body, carbon monoxide will combine with hemoglobin in the blood, so that hemoglobin can not be combined with oxygen, causing hypoxia in the body tissues, causing the body to suffocate and die. Therefore, carbon monoxide is toxic. Carbon monoxide is a colorless, odorless, odorless gas that is easily overlooked and poisoned. Gas hazard: Carbon monoxide will harm our human health. If carbon monoxide poisoning is bad, it will lead to death. So remind everyone to use gas safely. Comrades working in the factory should also pay attention to the concentration of carbon monoxide! The pumped carbon monoxide detector TEST-4 is a flexible single-gas or multi-gas detection alarm that can be equipped with an oxygen sensor, a flammable gas sensor and a toxic gas sensor or any four gas sensors or optional. Single gas sensor. The pumped carbon monoxide detector TEST-4 has a very clear large liquid crystal display, sound and light alarm prompts, and a built-in pump to ensure that dangerous gases can be detected in a very unfavorable working environment and promptly advised by the operator. Pumped carbon monoxide detector TEST-4 features -The self-contained air pump can measure the gas from the tens of meters away from the instrument for measurement. -Audible alarm - Large screen numbers, character display, instantaneous value, peak display - Self-test for display, battery, sensor, sound and light alarm function when booting or when needed -Safety Tip: Regular flashing lights, voice prompts - Superior audio sound alarm -With charger, easy to carry and flexible to use - low maintenance costs Carbon monoxide product inspection method Fast and accurate measurement of carbon monoxide content with an easy-to-use, compact test pen With a carbon monoxide test pen, carbon monoxide levels can be measured quickly and accurately with a single compact unit. With the latest generation of electronic chemical sensors, it is possible to quickly detect changes in the concentration of carbon monoxide in the surrounding environment without the use of a suction pump. Ideal for technicians and professionals who need to measure carbon monoxide concentrations in environments such as industrial environments, commercial buildings or residential areas where combustion gases may accumulate. Carbon monoxide instrument characteristics * Robust outer casing and robustness of electronic features * Display 0 to 1000 ppm carbon monoxide concentration on a large LCD display * Bright backlighting for clear reading of carbon monoxide detector even in dimly lit environments * When the concentration of carbon monoxide increases, the buzzer frequency will also increase. * Maximum hold function to store and display the maximum carbon monoxide concentration value * Sensor auto-zero and self-test sequence at startup. * The carbon monoxide concentration buzzer can be turned off. * When not in operation for 20 minutes, it will automatically light the pen to extend battery life. * Easy to replace the battery * Replaceable probes extend the life of the tool. * C50 soft carrying case, battery and instruction card. * Stable electronic chemical carbon monoxide sensor * Sensor life (typical) for up to three years: calibrated once a year. * Alkaline battery life is 500 hours (typical) Home security explosion-proof certification: The circuit is designed in accordance with the requirements of the national safety requirements. And won the national intrinsic safety certification certificate: EXia II CT6 (intrinsically safe type) Fool-type operation: The intelligent hand-held pump-type carbon monoxide detection recorder is designed to be simple and convenient to use, and the operation is very simple. Almost no need to read the instructions, the machine gets a look at the hand to understand how to use. High precision: The product adopts pumping type, foreign well-known brand sensors, advanced circuit design and filtering technology to ensure the high precision of the product. (1) Pumping type: The intelligent hand-held pumping type carbon monoxide detecting recorder adopts pumping type. The stability of the airflow in the air chamber and the stability of the air pressure are ensured, and the environment is paved for improving the accuracy of the instrument detection. (2) The use of internationally renowned brands of gas sensor components and IC components: well-known brand components are better in terms of anti-interference and stability, this is to prepare the hardware for improving the accuracy and stability of the product. (3) Advanced filtering technology: The filtering technology extracted from the research and development experience of gas detection products for many years provides technical guarantee for high precision of products. High-capacity storage: It can store 100,000 pieces of data, and can be stored once in one second, once in 10 seconds, and once in one minute. Then connect your computer to print. Large battery capacity: The instrument battery capacity is 2800Ma, which can work continuously for more than 90 hours. Alarm function: Intelligent handheld pump suction type carbon monoxide detection recorder with double alarm of buzzer and led light. The alarm value has two levels, high and low. The alarm value can be set by itself. Automatic diagnosis: The intelligent handheld pump-type carbon monoxide detection recorder has a system self-diagnosis function. When the device has a low battery, indicates a fault, the sensor reaches the end of life or fault, hardware failure, etc., the device will automatically alarm.
