SIBATA PM2.5 Sampler LV-250R

SIBATA PM2.5 Sampler LV-250R,This PM2.5 sampler is capable of mass concentration measurements of microscopic particulate matter (PM2.5) using a filter, based on the standard measurement method designated by the Japanese Ministry of the Environment.

With this sampler, airborne particles in environmental air are aspirated in at a constant flowrate via a suction port. PM2.5 particles passed through an impactor are then collected on a filter. Suction flowrate changes are minimized by a constant flowrate unit equipped with temperature and air pressure correction features, so the particle separation characteristics of the impactor are kept constant. The temperature of the filter unit is controlled so that it is always within 5 ℃ of the external air temperature. This prevents revaporization of volatile matter contained in the PM2.5 particle sample.

● The particle size separator used is compliant with the standard measurement method designated by the Japanese Ministry of the Environment.

● The constant flowrate unit keeps the suction flowrate constant, thus maintaining the particle separation characteristics of the impactor.

● It automatically corrects the suction flowrate for changes in the external air temperature or air pressure (actual flowrate control).

● It maintains a stable suction flowrate even with increases in filter pressure loss.

● The timer feature enables the user to set the sampling start time and stop time.

● The flowrate, time, temperature, and pressure are displayed.

● It is capable of storing (logging) measurement values, for processing on a computer. (A separate communication cable with software is required.)

● If a power outage causes a temporary stop, or problems with the flowrate or filter temperature occur, the time of the occurrence is recorded.

● The exterior has a urethane coating.,
