Instrument Calibration in Kenosha & Pleasant Prairie, Wisconsin

Just across the state line from our Antioch, IL headquarters: on-site and in-house calibration for southeast Wisconsin plants.

A calibration partner just across the state line

CML Enterprises is headquartered in Antioch, Illinois, at the Illinois–Wisconsin state line — right next door to Kenosha County. That makes CML a practical, local choice for manufacturers and processors in Pleasant Prairie, Kenosha and the surrounding southeast Wisconsin corridor who want NIST-traceable calibration without shipping instruments across the country.

We calibrate pressure, temperature and electrical instruments on Beamex MC6 equipment, track every instrument in Beamex CMX, and issue certificates in paper or electronic format — on site at your facility or in our shop.

Calibration services available

In-house calibration

Drop off or ship gauges, transmitters, switches, RTDs, thermocouples and thermometers to CML for inspection, as-found testing, repair if needed and full multi-point calibration.

On-site field service

Our technicians calibrate installed pressure and DP transmitters, temperature loops, chart recorders, pH systems and lab scales at your facility — on demand or on a schedule.

Switch & system testing

Set-point adjustment and testing of pressure, temperature and level switches; hydrostatic pipe testing; pressure and temperature data logging.

Records & certificates

NIST-traceable certificates in paper or electronic format, with every instrument tracked in Beamex CMX for scheduling and interval analysis.

Built for southeast Wisconsin plants

From food and beverage lines to manufacturing, utilities and labs, corridor facilities rely on transmitters, gauges, switches and temperature loops that need regular, documented calibration. CML can take on a routine calibration program, handle on-demand calls, or calibrate spares and pulled instruments in-house. Our Antioch & Lake County page covers the Illinois side of the corridor.

Why a local, women-owned calibration partner

  • Close by. Our headquarters is in Antioch, IL, north of Chicago at the state line, with a second Illinois location in Bolingbrook — not a distant national lab with a local landing page.
  • Process-instrument specialists. Transmitters, P/T loops, HART and Fieldbus, switches and seal assemblies are our daily work.
  • One supplier. We calibrate, repair and supply the instrument — including diaphragm seal and capillary assemblies.
  • WBE since 1988. A 100% women-owned business that supports your supplier-diversity goals.

Proven at demanding sites

Our field calibration customers include Argonne National Laboratory, Nestlé Professional Beverages, the Metropolitan Water Reclamation District and wastewater treatment plants across Illinois, Indiana and Iowa. Read testimonials.

“CML Enterprises performed calibration services of differential pressure transmitters for critical systems used for protection of both personnel and equipment. They did the work during tight time frame of the facility that operates 24/7 with impressive efficiency and knowledge. We are very satisfied with CML performance and plan to continue using their services.”

Gene S.Argonne National Laboratory

“Over all, I just want to say that Bob and Bobby are excellent people. They really know how to represent CML Enterprises. I highly recommend their calibration services, they are flexible and very reliable. They work hard and they will do anything they can, to get those instruments up and running. Great job I will look forward to work with you next year. Thank you.”

Santiago G.Nestlé Professional Beverages

“CML Enterprises worked with my team to calibrate several unique pressure transmitters at our facility over the course of two days. The transmitters were of varying types and often located in difficult to reach locations. Bob and Rob were extremely helpful throughout the process and completed the work well within the allotted time frame. I’m happy to recommend their services to anyone in the industry, and look forward to continuing our relationship.”
