PTH-4 Carbon Dioxide Detector Carbon Dioxide Alarm with Digital Display

Features:
Digital Display: Comfortable expressions, indicators that change color according to different levels of carbon dioxide concentration, allow you to easily grasp the current state of carbon dioxide concentration in the air.
Accurate and Reliable: The carbon dioxide detector is equipped with a high-performance sensor based on the principle of non-dispersive infrared absorption. It relies on a super denoising circuit and a hybrid algorithm, and its concentration detection resolution can reach the PPM level.
Honeycomb Heat Dissipation Design: The honeycomb heat dissipation design on the back not only ensures that the sensor is in full contact with the air but also facilitates heat dissipation, reducing false alarms due to excessive temperature and insufficient contact with the outside air.
Long Standby: Built-in 2400mah rechargeable battery, with low battery reminder function, can be used while charging, long standby, long standby time of 100 hours.
Warranty: If there are any problems, please contact our store in time. We will give you a satisfactory solution. Thank you for your understanding.
