Performance characteristics

• Accredited according to ISO/IEC 17025
• Traceable to National Standards
• Temperature controlled to within ±0.5 °C (± 0.9 °F) at atmospheric pressure and humidity
controlled
Flanged version:
±1.5 % of reading for 100 % to 20 % of full scale at reference conditions
±0.3 % of full scale for 20 % to 1 % of full scale at reference conditions
Insertion version:
±1.5 % of reading plus ±0.5 % of full scale
Note!
• Calibration gas is normally air at reference calibration conditions and with a fully developed flow
profile.
• On site performance is dependant on the standard of installation.
0.5 % for velocities above 0.2 m/s (0.65 ft/s)
Typically less than 2 seconds for 63 % of a given step change (in either direction).
