On-Site Field Calibration & Instrument Service
Our technicians come to your plant for on-demand or routinely scheduled calibration, switch testing, hydrostatic testing, data logging, emergency service and installation supervision.
Keep instruments in service — and in spec
CML Enterprises has extensive experience providing field calibration on a wide range of instrumentation for our customers, working on most manufacturers’ equipment. Experience has shown that routinely scheduled inspection and calibration saves money by maintaining accurate process control and by detecting potential problems early — before they turn into downtime, scrap or a failed audit.
Field work is performed with portable, high-accuracy Beamex MC6 calibrators, and results flow into our Beamex CMX database, so on-site calibrations produce the same NIST-traceable certificates and history as shop work.

Routine programs or on-demand calls
Routine scheduled calibration
Hand us your instrument list once. We build it in Beamex CMX, schedule upcoming calibrations and use history trend analysis to help optimize intervals — so you calibrate what needs it, when it needs it.
On-demand & emergency
A suspect reading, a failed transmitter, an auditor on the way — call for on-demand emergency service. Tell us what’s happening and where, and we’ll confirm what we can do and when.
Testing & data logging
Hydrostatic pipe testing, pressure and temperature data logging, and set-point adjustment and testing for pressure, temperature and level switches.
Installation supervision
Experienced oversight when new instruments go in, so they’re installed, configured and documented correctly from day one.
Who we’ve served in the field
We have provided field service calibration for these companies and industries, to name a few:
- Argonne National Laboratory — DP transmitters on critical personnel- and equipment-protection systems in a 24/7 facility
- Nestlé Professional Beverages — food & beverage production calibration
- Metropolitan Water Reclamation District
- Wastewater treatment plants throughout Illinois, Indiana & Iowa

Where we work
Our headquarters is in Antioch, Illinois, right at the Illinois–Wisconsin state line, which makes Lake County, Illinois and the Kenosha / Pleasant Prairie, Wisconsin corridor a natural fit for field service. A large share of our field work is in the Chicago area, served from Antioch and our Bolingbrook, IL location in the southwest suburbs, and we have a Michigan location in Fennville. See service areas.

Field service, in our customers’ words
“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.”
“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.”
“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.”
