Products Description

CW-HPC300 ultra-thin handheld laser dust particle counter is an instrument used to measure the number and distribution of dust particles per unit volume in the atmosphere.
The basic principle is that after the laser is scattered by dust particles, the pulse signal output by the optical sensor is
processed by digital signal and the measurement parameters are set, which can monitor the working status of the laser particle sensor.
The instrument is designed in accordance with the international standard ISO14644-1 and GMP standards, and can simultaneously detect three particle sizes (the user can set the particle size to be measured at will), and the sampling time is up to 59 minutes and 59 seconds.
The built-in flash memory can store up to 1000 sampling data and can be downloaded at high speed via the USB interface.
The instrument has the characteristics of high test accuracy, stable performance, strong versatility, simple and convenient
operation, etc., reaching and exceeding all performance indicators of similar products in the world.
It is the smallest and thinnest handheld particle counter in the world and can be widely used Production enterprises and
scientific research departments such as computer room and indoor environment.

Features:
1. Simultaneously sample, analyze and print three channels of user-defined particle size
2. Sampling mode: concentration/liter
3. 1000 measurement data storage
4. Automatic timing sampling and over-limit alarm
5. USB interface, data download and software upgrade
6. External temperature and humidity sensor to ensure test accuracy

Application:
1. Indoor environment testing
2. Filter efficiency analysis test
3. Check pollution source analysis
4. Analysis of particle size distribution
