FVM and Twin Pines Metrology, divisions of WESTport Corporation use state of the art equipment to ensure the highest degree of measurement uncertainty. With this equipment, and our custom-designed software, we are able to offer you the best possible turnaround time, and pricing in the industry. The hard gage calibration lab is held at 68°F with relative humidity not to exceed 45%. Both temperature and humidity are closely monitored by our Honeywell environmental control unit. We also have a suspended floor to help avoid unnecessary vibration and ensure a good measurement uncertainty of all of our equipment.

When your gages come into our ISO/IEC 17025 accredited hard gage lab, they have already been thoroughly cleaned and inspected for shipping damage. Gages sit in the lab for 24 hours in order to acclimate to the proper laboratory conditions. When the gages are calibrated, they are also closely inspected for nicks, burrs, and corrosion; then re-cleaned and stickered. When packaged for return, gages are either coated in dip-seal, or oiled and wrapped in bubble wrap, and boxed securely. Calibration pricing includes cleaning, and level 4 certification. Average turnaround time is 1-3 days.

Hard Gage Calibration and Repair

Partial Equipment Listing

Pratt & Whitney Laserruler

The Pratt & Whitney Laserruler is a linear machine with 8 inches of travel and a   measurement uncertainty of 5µin through 7 inches. It can be set up to calculate the temperature coefficient and adjust for humidity, barometric pressure, etc. Capabilities include: Plug gages, Pin Gages, Gage Blocks (grade 3 and under), Depth Mic Masters and Thread Wires.

Pratt & Whitney Supermicrometer

The Pratt & Whitney Supermicrometer has a 10 inch travel and a measurement uncertainty of 17µin over 1 inch of travel. It is extremely accurate for thread gaging. With a RS232 output that is directly networked to our software, we are capable of entering data at the touch of a button. Some capabilities include thread plugs, thread setting plugs, thickness gages, and length standards.

ULM Opal 600 Universal Linear Measurement Machine

ULM Opal 600 Universal Linear Measurement Machine is used to measure cylindrical rings, non-standard thread rings, length standards and gage blocks up to 24". The Opal features computer assisted temperature correction.

Helios UMG50 Plug Gage Comparator

Helios UMG50 Plug Gage Comparator is used to calibrate cylindrical plug and pin gages, thread plugs and thread setting plugs up to 4" in diameter. The portable size of this comparator allows us to come in to your facility to perform on-site calibration.

Tesa Dual Head Gage Block Comparator

Tesa Dual Head Gage Block Comparator is used to check gage blocks that are Grade 2 and higher. This comparator also gives us the ability to check the flatness of your gage blocks.

The Series 400 Amplifier
The Series 400 Amplifier is a sophisticated yet easy to use instrument with a modular surface texture program. All models feature a vacuum fluorescent display and sealed membrane keypad. An RS-232 communication port is standard (RS-485 optional), along with a remote start switch port and lockout key switch. Battery power is included on all models with the graphic plotter, and is optional on all other models.

Operation is at once simple, sophisticated and secure. The instrument is configured by an easy-to-use set-up menu. The user selects the proper settings for the cutoff, stroke length, standard 2RC and Gaussian filters (Rk filter optional), parameter functions, serial port and plotter operation. Set the exact stroke length required or use the standard 5-cutoffs. After setting, the programming can be secured by a turn of the lockout key, which prevents inadvertent changes. Once configured, the system operates by pressing the Start Button or through use of an optional remote start switch.
