SATO Keiryoki SK-40CTH thiết bị đo nhiệt độ, ẩm và nồng độ khí CO2 (400 ~ 5000 ppm)

SATO KEIRYOKI Japan 

CO2 Monitor Mini

Model : SK-40CTH (CO2 level 400 to 5000 ppm )

The Sato Keiryoki SK-40CTH is a CO2 monitor used to measure carbon dioxide concentration, temperature, and humidity to help determine the need for ventilation in various indoor spaces. The primary function of the SK-40CTH is to ensure adequate ventilation in public places, offices, schools, restaurants, and factories to help prevent the spread of airborne infections, such as COVID-19, which thrive in poorly ventilated areas.   

Features

• Test report + calibration certificate included
• Small-sized CO2 monitor
• Equipped with non-dispersive infrared CO2 sensor (NDIR)
• Three levels of alarm settings are possible. A buzzer sound and a face icon will notify you when it is time to ventilate. Setting range: 600 to 3000 ppm (in 100 ppm steps)
• Buzzer sound: ON/OFF possible
• Along with CO2 concentration, temperature, humidity and dew point are also measured.
• Battery life: up to 1 year
• There are four installation methods: tabletop (stand), wall-mounted (hook hole), fixed to prevent theft (screws), and attached to a metal surface (magnet).
• Displays the average value for the past 24 hours and 8 hours, and the highest value for the past 24 hours. (To clear, turn the power off.)
• Equipped with key lock function
• When Eco Mode is ON, the measurement interval is about 60 seconds: Battery life is about 1 year When Eco Mode is OFF, the measurement interval is about 10 seconds: Battery life is about 6 months (using alkaline batteries, when the buzzer sounds once a day)
• With automatic calibration function. The minimum value during the period is automatically calibrated to 400 ppm every 7.5 days. If there are no people in the place of use such as at night or on holidays, the CO2 concentration will be the same as the outside air. Please turn it on in such an environment. *With manual calibration function

• Monitoring air quality: It provides accurate measurements of CO2 levels, an effective indicator of air stagnation and poor ventilation.
• Ventilation guidance: The device features an LED light and buzzer alerts that change color and sound based on CO2 concentration, suggesting the optimal time to ventilate a room.
• Environmental monitoring: In addition to CO2, it simultaneously measures and displays temperature and humidity, helping to maintain a comfortable and healthy environment.
• Automatic calibration: The monitor includes an automatic calibration function, which adjusts the baseline CO2 level to 400 ppm (parts per million) every 7.5 days, usually during nighttime when the space is empty, ensuring long-term accuracy

Maintenance and calibration :  ► We also have calibration certificate attached ( optional ) ► Please re-calibrate after use for a certain period through our purchase store.
