Fox Valley Metrology is comprised of five different calibration labs: a hard gage calibration lab, a dimensional inspection lab, an electronic calibration lab, a hand tool calibration & repair lab and a field service technicians group.

The hard gage calibration lab calibrates many different types of gages: blocks, rings, cylindrical rings, gage blocks, tapered thread rings, etc.

Our dimensional inspection lab specializes in performing dimensional inspections using state of the art software and inspection equipment such as the Zeiss Eclipse and the COORD3 ARES CMM. We also have the capabilities to do full non-contact vision inspection.

The electronic calibration lab calibrates many different types of electronical equipment including digital multimeters, thermocouples, function generators, etc.

Our field service technicians group has the ability to travel to your place of business to perform calibrations on your hard gages, electronics or hand tools. This minimizes any downtime your company might have experienced by sending them out.

The hand tool calibration and repair lab is responsible for calibrating and repairing many different hand tool types such as pitch micrometers, indicator calibrators, dial snap gages, etc.

Fox Valley Metrology uses state of the art equipment to ensure the highest degree of measurement uncertainty. With this equipment, and our custom-designed software, FVM is 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 the 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 our lab 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. Currently, our average turnaround is 3-4 days.

Precision Devices, Inc. Profilometer

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.

The Skid-Reference Piloter
Skid-referenced systems are designed to measure normal I.D., O.D., and flat surfaces. The skid-referenced motor drive (piloter) contains a motor which moves the linkarm with the tracer across the surface to be sampled. The tracers have skidpads which establish a reference line. The transducer translates the vertical motion of the diamond tip stylus in relation to the reference line. The piloter traverses at a speed of 0.1 in/sec (2.54 mm/sec) for the travel length specified and can be set to acquire data in either direction. Our patented Lite-Touch Linkarm protects the tracer and surface from inadvertent damage and comes standard with each system, unless otherwise specified.
