Some of the Calibration Services CIH Offers

Sound Meter/Noise Dosimeter

CIH calibrates both noise dosimeters and sound level monitors. Sound level meters are commonly used in noise pollution studies for the quantification of different kinds of noise. Meets ISO/IEC 17025:2017 and ANSI S1.4-1983(R2006).


Flow Meter Calibrator Calibration

CIH uses the MESA Laboratories ML800 primary piston prover for unmatched accuracy.  The ML-800 is a positive displacement primary piston prover for gas flow measurements in either pressure or vacuum applications.


Air Velocity/Wind Speed Calibration

Our GDJ 360 Benchtop Wind Tunnel is designed to give a highly uniform flow rate with our test section being over 152mm with a variable adjustable speed from 0 to 6,000 FPM. Each measurement is directly compared against our ISO: 17025 calibrated anemometers.


Air Sampler Pump Calibration

We go through the pneumatic system, charging system, ensure constant flow, constant pressure and the electronics are in peak performance mode when your sampler goes through our systems checks and maintenance details.
