When purchasing a carbon dioxide recorder, we should start from these six aspects
The carbon dioxide recorder is a common gas detection device, which is specially used to measure the concentration of carbon dioxide, and is mostly used in agricultural greenhouses. Like other gas detectors, it is best to start from the following aspects when purchasing a carbon dioxide recorder!
1. Reliability - The longer the life of the gas detector sensor, the better. Generally speaking, the life of the sensor is generally 2-3 years, and the life of the flammable gas sensor is 3 years. The longer the mean time to error, the better. What is the accuracy and precision, the smaller the error value, the better. The product warranty period is generally 1 year.
2. Stability——What is the zero offset and full offset value of the carbon dioxide recorder, the smaller the better.
3. Convenience - light weight, small size, easy and comfortable wearing, easy maintenance.
4. According to the measurement object and measurement environment - determine the type of sensor according to the measurement object and measurement environment. To carry out a specific measurement work, we must first consider what kind of sensor is used, which needs to be determined after analyzing various factors.
5. Response time - the frequency response characteristics of the sensor determine the frequency range to be measured, and must maintain undistorted measurement conditions within the allowable frequency range. In fact, the response of the sensor always has a certain delay. It is hoped that the delay time should be as short as possible. .
6. Linear range - The linear range of the carbon dioxide recorder sensor refers to the range in which the output is proportional to the input. In theory, within this range, the sensitivity remains constant. The wider the linear range of the sensor, the larger its range and can guarantee a certain measurement accuracy.
