NIST-Traceable Instrument Calibration Services

Calibration that protects your process, your product and your audit trail

Instrument drift is quiet and expensive. A pressure transmitter reading a little high, an RTD that has wandered a few tenths, a switch that trips late — each one erodes quality, energy efficiency and safety margins long before anyone notices. CML Enterprises Inc. provides full-service calibration and certification for numerous pressure, temperature and electrical instruments so your readings stay trustworthy.

Every calibration is performed with high-accuracy, all-in-one Beamex MC6 calibration equipment, and all instrument calibration and certification is traceable to national and international measurement standards (NIST). For each instrument we perform an inspection, initial (as-found) tests, any needed repairs, and a full multi-point calibration — then we issue certificates with calibration reports in paper or electronic format.

What we calibrate

CML can perform inspections, initial tests, repairs and full multi-point calibrations across these measurement types:

Instruments in our calibration scope

CML has the capability to calibrate a broad range of process instruments, including:

Don’t see your instrument? Call us — our technicians work with most manufacturers’ equipment, and we’ll tell you plainly whether it fits our scope.

In-house or on-site — your choice

In-house (ship-in or drop-off): send instruments to CML and we inspect, test, repair if needed, calibrate and certify them in our shop. Ideal for spares, gauges, switches and anything easily removed.

On-site field service: our experienced technicians come to your plant for on-demand or routinely scheduled calibration of installed transmitters, temperature loops, recorders, pH systems and scales — plus switch set-point testing, hydrostatic pipe testing, data logging and emergency service. See field service capabilities.

Records you can actually use

CML uses Beamex CMX calibration software to build a database of every customer instrument. It stores data and reports, plans and schedules upcoming calibrations, and lets us analyze calibration history to optimize intervals based on your needs. Year over year, that history shows which instruments are drifting toward repair or replacement. How CML manages calibration records.

How a calibration job works

1. Send your listShare an instrument list (or just tell us what you have), plant location and whether you prefer in-house or on-site service.
2. Confirm scopeWe confirm instruments, ranges, test points (3-point, 5-point or custom up & down) and scheduling, then quote.
3. Inspect, test, calibrateAs-found tests, any needed repair or adjustment, then full multi-point calibration on Beamex MC6 equipment.
4. Certify & recordNIST-traceable certificates and reports in paper or electronic format, with results stored in Beamex CMX for next time.

Why plants choose CML

• Calibration plus supply plus repair. The same team that calibrates your instruments can repair them, build diaphragm seal and capillary assemblies, and source replacements.
• Women-owned business since 1988. CML was incorporated as a 100% women-owned business — useful for supplier-diversity programs.
• Proven at demanding sites. Field calibration for Argonne National Laboratory, Nestlé Professional Beverages, the Metropolitan Water Reclamation District and wastewater treatment plants across Illinois, Indiana and Iowa.
• Local to the IL–WI corridor. Headquartered in Antioch, Illinois, with locations in Bolingbrook, Illinois and Fennville, Michigan.
