MET227A MET227B air laser particle counter product code: 212411 origin: The United States
Products:
227 hand-held laser particle counter air particle counter with large-scale performance and sensitivity, it is easy to operate small light, with the use of reliable laser diode technology, and remote printer or a computer linked, can also be used as part of the process control system .
227 at the same time on the size of the two test, the sample time of 24 hours a sampling of data stored in the built-in cache can be transferred to a computer or printer. 227 have applied to a variety of clean-room analysis of the counting mode: the concentration model can be given for cubic feet per liter, or the number of particles; automatic mode in accordance with the apparatus can set the time between sampling time and automatically, without control; average model Calculate the average, maximum and minimum value; alarm mode filter for the leak location, as designated by the particles detected in a few hours sounds alarm.
in order to protect the clean room environment, bring their own 227 exhaust filters. When the battery down to below the level of safe operation, pumps and sensors automatically shut down to ensure that the working memory capacity.
