Description
The DT-9880 particle counter is intended for control of dustiness of special production rooms, and also can be used for check of filtering devices. The device measures the calculated concentration of particles in six dimensional ranges, and also estimates the mass concentration. DT-9880 is a multifunctional device for ecological analysis of the environment. The device allows to measure concentration of suspended solids in air, temperature and humidity of air, and also to define temperature of a dew point and temperature of the damp thermometer.
In addition, the device is equipped with a gas analyzer for measuring the concentration of formaldehyde HCHO and carbon monoxide CO, as well as a pyrometer with a laser pointer for non-contact temperature measurement. The DT-9880 can operate in recorder mode, collecting data on a MicroSD memory card and transferring it to a computer via a USB interface for further analysis. During data registration, the device can take photos and videos on the built-in camera.
In addition, this device automatically detects the dew point temperature, performs industrial measurements and analyzes data from realistic images and recordings on a color TFT LCD screen. All readings and images are stored in MicroSD memory. The user can then view the measurement results on a personal computer.
