Fox Thermal Instruments’ calibration tunnels are calibrated at appropriate intervals, monitored for stability, and under the custody of trained laboratory personnel. Measurement assurance procedures and monitoring results are maintained in the laboratory database to ensure that all calibrations are accurate, verifiable, and traceable to NIST primary standards.
Calibration capabilities range from as low as 0.02 SCFM (.03 NM3/H) to 3000 SCFM (4800 NM3/H) and higher for line sizes larger than 6 inches (150mm). The Calibration Lab is also equipped to calibrate applications with temperature ranges from -40 to 650F (-40 to 343C) and pressure ranges from 0 to 500 psig (0 to 35 barg).
Fox Calibration Lab equipment includes:
- 2 closed loop high flow air and gas tunnels;
3” to 6” (80 to 150mm) typical
- 1 closed loop medium flow air and gas tunnel;
½” to 3” (15 to 80mm) typical
- 1 low flow bell prover air and gas tunnel;
¼” to 1½” (6 to 40mm) typical
- 1 open loop high temperature air tunnel;
1” to 4” (25 to 100mm) typical
