Matheson has a fully equipped laboratory and has developed many special procedures for calibrating flowmeters to different gases and/or conditions.
For this service, MATHESON will calibrate a direct reading FM-1000 or FM-1050 rotameter and provide an NIST traceable certificate that states the rotameter is within published tolerance. (Typically +/-5% of the full scale flow rate.)
A separate calibration service must be ordered for each rotameter. So for example, if three rotameters need to be certified, then a quantity of three calibration certificates must be ordered.
NOTE: Please allow one week for this calibration service.
