Illumination up to 20'000 lux. Noise level from 35 dB to 130 dB at frequencies from 30 Hz to 10 kHz.The functions of the thermometer, hygrometer, luximeter and sound level meter are realized in CEM DT-8820 with the help of special sensors connected to a single digital unit. Due to its wide functionality, the CEM DT. 8820 is effectively used to monitor the environment in industrial and domestic conditions. For example, in the work of labor protection services when checking the compliance of working conditions with sanitary and technical standards in terms of noise and illumination at enterprises, in educational and medical institutions. If it is necessary to control the temperature of gas or liquid media, as well as the surface of objects up to + 750 ° C, a special sensor with a thermocouple is connected to the CEM DT-8820. The illumination level is measured using an external photodiode, and a condenser microphone is used to measure the noise level. The data obtained are displayed on a liquid crystal display with a resolution of 2000 samples. If necessary, the reading can be locked in DATA HOLD mode.
In addition to measuring current values, the CEM DT-8820 air quality meter provides the ability to determine the maximum values of the parameters. When the measured value is outside the set range, a special OL indicator is triggered. Also, the device provides a warning about low battery level (BAT).
A convenient and durable housing reliably protects the CEM DT-8820 from moisture, dust and mechanical damage. The instrument is controlled by several buttons, and the power is supplied from a battery of the Crown type or 6F22. The air quality meter automatically turns off after 10 minutes of inactivity, which saves a lot of battery life. 8820 will be an advantageous solution for performing complex monitoring of various environmental parameters with the help of only one device.3'/ 2-digit LCD display.
