CO2 concentration meter "CO2 Lamp"

CO2 concentration meter "CO2 Lamp"

As a measure for infection prevention! From a distance and in all directions 360°, we will inform you of ventilation guidelines with "light."

The "CO2 Lamp" is a compact and space-saving CO2 concentration measuring device that can be installed anywhere without needing a specific location. The large light source at the top allows for visibility from a distance and from all angles (360°). If the CO2 concentration rises, it will notify you with color changes and a buzzer, thereby visualizing the room's condition and encouraging ventilation. The "Photoacoustic (PAS) CO2 Sensor" is different from a simple gas sensor; it utilizes the fact that CO2 reacts to infrared wavelengths, similar to the non-dispersive infrared absorption method (NDIR) recommended by the Ministry of Economy, Trade and Industry. It accurately detects the concentration of carbon dioxide in enclosed spaces. 【Features】 ■ Compliant with the Niigata Prefecture Infectious Disease Control Certification System ■ Reliable Japanese production from manufacturing to packaging ■ Notifies concentration levels with a large light source and buzzer ■ Equipped with next-generation CO2 sensor (photoacoustic type) ■ Design that blends into interior spaces *For more details, please refer to the PDF document or feel free to contact us.

Carbon dioxide (CO2) concentration meter

Carbon dioxide (CO2) concentration meter

The timing for ventilation is easily understood. Monitor carbon dioxide levels with a CO2 sensor and maintain them below 1000 ppm through appropriate ventilation!

Infection control measures require frequent ventilation. The carbon dioxide concentration (CO2 concentration) can be considered a guideline for ventilation. It is equipped with a high-precision CO2 sensor using NDIR technology. Visualize CO2 anywhere! Compact size, self-standing, no installation required. Can be installed in various locations. Ministry of Health, Labour and Welfare recommended standards: The Ministry of Health, Labour and Welfare recommends installing CO2 sensors indoors as a measure against infectious diseases, monitoring carbon dioxide concentration, and maintaining it below 1000 ppm through appropriate ventilation. The outdoor carbon dioxide concentration is said to be about 400 ppm, and in enclosed spaces like indoors, exceeding 1000 ppm can lead to feelings of fatigue, drowsiness, and shortness of breath. Regular ventilation is necessary not only for infection control but also to maintain appropriate carbon dioxide levels.

Exhaled Carbon Monoxide Concentration Meter / Model Number MF313050-310H

Exhaled Carbon Monoxide Concentration Meter / Model Number MF313050-310H

Carbon monoxide concentration meter required for smoking cessation treatment program.

■Effects of Carbon Monoxide (CO) on the Body CO is a colorless, tasteless, and odorless toxic gas that is produced when organic substances are incompletely burned. When inhaled, CO binds with hemoglobin in the blood, which carries oxygen, forming carboxyhemoglobin (COHb) and reducing the ability to transport oxygen. A lack of oxygen in the body can lead to shortness of breath and affect daily life, including the recovery and regeneration of bodily tissues. ■Nicotine Addiction Caused by Tobacco Cigarettes and heated tobacco products contain a substance called nicotine. When inhaled, nicotine triggers the release of dopamine (a substance that induces pleasure) in the brain, leading to feelings of pleasure. Nicotine begins to leave the body as quickly as 30 minutes later, causing symptoms such as "irritability" and "loss of concentration," which create a desire to obtain nicotine again. This is referred to as nicotine addiction, making it difficult for smokers to quit smoking solely based on their own will.

Ozone Concentration and Safety: Understanding Ozone Concentration

Ozone Concentration and Safety: Understanding Ozone Concentration

A lower concentration inside the building is recommended compared to "about 8 hours of work"!

The unit used to measure ozone concentration is called "ppm." This is an abbreviation for "parts per million," which represents "how many parts per million" and indicates the amount of ozone present in the air. This article includes conversion tables between "ppm" and "%" as well as the occupational environmental standards from the Japan Society for Occupational Health. Please take a moment to read it. *For more detailed information, you can view it through the related links. Feel free to contact us for further inquiries.*

Ozone Concentration and Safety: Is the concentration of your ozone generator safe?

Ozone Concentration and Safety: Is the concentration of your ozone generator safe?

The amount of ozone generated may decrease due to various conditions such as temperature and humidity.

When using an ozone generator, the method for measuring the concentration in the air is typically done with an "ozone meter" or "ozone concentration meter." However, in reality, few people purchase machines that cost tens of thousands of yen solely for the purpose of measuring ozone concentration. So, what should be used to determine the ozone concentration? It is the ozone generation amount from each ozone generator manufacturer. *For detailed content of the column, you can view it through the related links. For more information, please feel free to contact us.*

[Labor Accident Case] Carbon monoxide poisoning due to incomplete combustion of a gas oven.

[Labor Accident Case] Carbon monoxide poisoning due to incomplete combustion of a gas oven.

We will introduce a case study from a workspace with a gas oven in a Japanese and Western confectionery manufacturing factory.

This is a case from a workspace with a gas oven in a Japanese and Western confectionery manufacturing factory. A gas oven was used without a duct to discharge combustion gases (LP gas) after combustion, and the exhaust fan was not turned on. The windows and entrances were kept closed except during entry and exit, leading to exposure to carbon monoxide generated by the gas oven during work. The worker complained of symptoms such as headaches and nausea, and upon rushing to the hospital, it was determined to be carbon monoxide poisoning. The worker with severe symptoms took a day off. 【Suggestion】 ■ It is recommended to measure the gas concentration in the work environment to check for the presence or accumulation of gas. *For more details, please refer to the PDF document or feel free to contact us.
