Calibration Services

We can recalibrate McGill orifice tubes and calibrate tubes that you supply. The 6- and 8-inch tubes come standard with forward flow (positive pressure) and reverse flow (negative pressure) calibration. The 4- and 5-inch tubes come standard with forward flow calibration, but can be calibrated for reverse flow. Our Engineering Department can also arrange for independent or NIST calibration and certification.

Positive Pressure (LTS-RP)
Negative Pressure (LTS-RN)
Positive and Negative Pressure (LTS-RB)

Calibration of Orifice Tubes Supplied by Customer:
Positive Pressure (LTS-CTP)
Negative Pressure (LTS-CTN)
Positive and Negative Pressure (LTS-CTB)

Independent Calibration and Certification:
Positive and Negative Pressure (LTS-IB)

NIST Calibration and Certification:
Positive Pressure (LTS-NP)
Negative Pressure (LTS-NN)
