Calibration

  • The uncertainty of measurement is reported as an expanded uncertainty having a level of confidence of 95% unless stated otherwise
Service Product Determinant Technique Procedure Limitations
Optical metrology - Particle measuring devices Aerosol photometers Flow rate; Linearity Comparison with a reference meter

Capability

Calibration of aerosol photometers with polystyrene latex (psl) particles
of nominal size 1 μm at flow rates of 2.83 to 120 L/min

with Calibration and Measurement Capability of -
Primary meter to secondary meter comparison;
6% for dilution ratio response;
Linearity -
2% at 100% scale reading;
3% at 80% scale reading;
4% at 60 % scale reading;
6% at 40% scale reading;
12% at 20% scale reading;
Flow rate -
From 0.05 L/min at a flow rate of 2.83 L/min increasing to 0.20 L/min at a flow rate of 55 L/min, and
From 1.11 L/min at a flow rate of 75 L/min increasing to 1.22 L/min at a flow rate of 120 L/min.
Particle counters - Air Flow rate; Particle count; Particle size Comparison with a reference meter; Comparison with a reference standard ISO 21501-4

Capability
