Instrument Calibration in Antioch & Lake County, Illinois
NIST-traceable pressure, temperature and transmitter calibration from our Antioch headquarters — in our shop or at your Lake County facility.
Calibration from our Antioch headquarters
CML Enterprises Inc. is headquartered at 595 Edelweiss Dr, Antioch, IL 60002. From here we provide NIST-traceable calibration, instrument repair and process-control supply to manufacturers, utilities, laboratories and food and beverage plants in Antioch and throughout Lake County, Illinois.
Whether you need a single critical DP transmitter certified before an audit or a full plant’s worth of gauges, switches and temperature loops put on a calibration schedule, our team brings high-accuracy Beamex MC6 equipment and Beamex CMX record-keeping to the job.

“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.”
“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.”
“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.”
