• The mass flow controller is received and visually inspected for damage.
• The mass flow controller is logged into our computer, which generates a worksheet displaying the proper standard and applicable calibration data.
• Pre-Calibration data is taken and graphed per customer request (additional fee).
• The mass flow controller is completely disassembled and ultrasonically cleaned.
• All seals are replaced and the mass flow controller is re-assembled under a class 100 clean hood.
• The sensor current and bypass adjustments are made.
• The mass flow controller is adjusted for proper valve tuning and response.
• The mass flow controller is tested for long-term drift.
• Calibration is performed to within +/- 0.2% FS at each calibration point with a calibration cover installed.
• Pre-shipment leak testing to the manufacturer’s specifications is performed.
• A Certificate of Compliance summarizing the calibration data and repair report is generated for your analysis and records.

Packaging and Shipping

• The mass flow controller is doubled bagged in anti-static sleeving, and sealed in clean dry Nitrogen (all removed parts are sealed and returned in a separate bag).
• The mass flow controller is then, double wrapped with bubble wrapping, boxed and packed with Styrofoam.

We utilize a unique (100% in-process) Quality Control System. Our Clean & Calibration procedures are divided into (4) processes:
(1) Cleaning, (2) Assembly, (3) Calibration and, (4) Shipping
Each process is inspected for defects or faults before it is transferred to the next station.
