DT-9681 is a modern, highly-advanced meter that allows simultaneous monitoring of PM2.5 / PM10, carbon dioxide (CO2), formaldehyde (HCHO) as well as temperature and humidity in real time.
Thanks to the innovative calculation algorithm, meter is characterized by exceptional precision and measurement stability. All measured values are displayed on a 3 inch color LCD display. An additional color indicator facilitates the quick recognition of harmful, critical concentrations of the measured particles.
Device has a built-in memory that allows to store up to 5000 measurement data. Meter is also equipped with a noise sensor, thanks to which even a small sound, e.g. a clap or slamming door, wakes the device from the sleep function and allows you to resume measurements (with the option of deactivating).
DT-9681 is powered by a built-in lithium-polymer battery with a capacity of 2400mAh, which lasts for about 4 hours of continuous operation. Power / charging can also be done using a microUSB cable. The time needed to fully charge the battery is approx. 2 hours. The meter has a function of automatic power off after a specified number of minutes (with an option to deactivate it).
