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.
If requested, pre-calibration data is taken and graphed per customer request (additional fee).
The mass flow controller is disassembled and chemically and ultrasonically cleaned.
All seals are replaced and the mass flow controller is re-assembled
The sensor current and bypass adjustments are made.
All electronic/mechanical adjustments required to meet the customer specifications are made.
The mass flow controller is tested for long-term drift.
Calibration is performed at each calibration point with a calibration cover installed.
Pre-shipment leak testing to the manufacturer’s specifications is performed.
AÂ Certificate of Calibration 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. (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.
