1. Incorporates imported semi conductive laser tubing and semi conductive light-sensitive receiver tubing, assures sensitivity and response speed.
2. Core component of the apparatus: Optical Scattering Sensor. Its structure enables it to effectively remove any diffusive light within the chamber, hence greatly reduces the noise level, thus making measurements more accurate and more reliable.
3. The ‘acceptance level’ measurement introduced to this apparatus makes it the only one among all similar sorts of counters to follow the requirements of both GP/T16292-194889, and makes automatic judgment to the purification classes.
4. Be able to save up to 300 measurement data, search among data enabled. Ready to connect to computer terminals.
5. The apparatus possesses temperature/humidity channel input, which enables it to monitor the temperature and meanwhile the humidity of the environment. Accessories: Relative temperature/ humidity sensors.
6. A pioneer product to use digital display of the flow rate, thus being more straight-forward in data-presentation and more accurate.
