The Extech CO240 is a versatile and easy-to-use tool for measuring carbon dioxide levels in indoor air. It is perfect for anyone who wants to improve the air quality in their home, office, or school.

Here are some additional details about the features of the Extech CO240:

The CO240 uses a non-dispersive infrared (NDIR) sensor to measure carbon dioxide levels. This type of sensor is known for its accuracy and long lifespan.
The CO240 has a range of 0 to 5,000 ppm. This means that it can measure carbon dioxide levels from very low to very high.
The CO240 has an accuracy of +/- 50 ppm. This means that the readings from the meter are accurate to within 50 parts per million.
The CO240 has a response time of 5 seconds. This means that it takes 5 seconds for the meter to display the current carbon dioxide level.
The CO240 is powered by 2 AA batteries. The batteries typically last for about 100 hours of use.
The CO240 is compact and lightweight. It measures just 5.5 x 2.5 x 1.2 inches and weighs only 4.2 ounces.
The CO240 has a user-settable high alarm with an audible beeper. This alarm can be set to go off when the carbon dioxide level reaches a pre-determined level.
The CO240 can also calculate dew point and wet bulb temperature. Dew point is the temperature at which water vapor in the air condenses to form dew. Wet bulb temperature is the temperature of a thermometer that has been wrapped in a wet cloth.

Overall, the Extech CO240 is a versatile and accurate carbon dioxide meter that is perfect for anyone who wants to improve the air quality in their home, office, or school. It is easy to use and has a variety of features that make it a valuable tool for measuring indoor air quality.
