New Release Ultrasonic CO2 Gas Sensor -7500B

The biggest advantage is maintenance-free

7500B-CO2 gas sensor can be used to measure carbon dioxide concentration based on ultrasonic technology which adopts ultrasonic velocity difference between upstream and downstream to realize measurement. The greatest advantage of ultrasonic technology for CO2 sensor is no-calibration needed in lifespan.The inside temperature of the gas sensor is higher than the outside which can avoid condensing events and high humidity influence. It is reliable and low cost to integrate into intelligent agriculture application, fruit and vegetable transportation and storage, etc.
