Dust measuring instrument

1. temperature compensation function 2. probe with blowback and cooling airflow system

TH-LRD-801 Dust  Measuring Instrument which is based on the principle of backscatter is used to continuously monitor particles of fixed pollution source.

Main function

            1. Temperature compensation function

               2. Smoke concentration signal 0V-5V or 4mA-20Ma analog output

               3.  probe with blowback and cooling airflow system, making the temperature of sensor substrate keep 50°C blew, cleaning the convex lens. 

Technical performance index:

                 1.  smoke concentration measurement range: 0.1mg/m3~1000mg/m3(can be extended), error can be controlled +/-5%

                 2. measuring instrument sensitivity can not be exceeded +/-2%

                 3.  stability :zero drift not exceeded±2.0%F.S/24h

                            Span drift not exceeded +/-2.0%F.S/24h

                 4.  response time (T95) not more than 5s
