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 FM-1050 rotameter or an FM-1000 and produce a reference scale flow chart for the gas service selected. Included is an NIST traceable certificate that states the rotameter is within a tolerance of +/-1% of the full scale flow rate.
A separate calibration service must be ordered for each rotameter and gas service. 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.
NOTE: There might be additional charge for the specific gas if we do not have it on site
