SAS PYRAMID

The microbiological air sampler should be regularly controlled according to Good Laboratory Practices and Good Manufacturing Practices to evaluate the correct functionality.
The laboratory technician should use an instrument to be sure the air sampler works according to the specifications of the producer. In fact battery faults, falls, etc. can damage the sampler.
The new “Pyramid” flow check by international pbi is a new easy to use, battery operated system that is applied to calibrate the air sampler. The instrument is composed by two separate units: a fan and a flow meter.
The “Pyramid” is positioned on the top of the sampler: The propeller produces an electric field that is proportional to speed of the air. The system measures the electromagnetic field and calculates the air flow that is presented on the digital visual display (litres per minute or cubic feet per minutes).
The battery has an authonomy of 3 years (30.000 tests) and is available with I.Q., O.Q. documentation.
Technical specification: Weight:890 grams
Measurement range: 70-200 litres per minute
Suggested operational temperature: +20°C (+/- 2°C)
Power supply: 3V type CR2032 lithium battery. The normal battery life is 30.000 measurements of 60 seconds
Reading: The LCD display can show the results in litres per minutes (L) or cubic feet per minute (CFM).
