Ashcroft Gauges, Switches, Transmitters & Diaphragm Seals — Chicago Area
CML supplies Ashcroft pressure and temperature instrumentation to plants across the Chicago area, northern Illinois and southern Wisconsin — and can calibrate and certify it, NIST-traceable, before it ships.

Ashcroft products from CML
Ashcroft is the first instrumentation line on CML’s product line card: pressure and temperature indicators and switches, pressure transmitters and transducers, diaphragm seals and test gauges.
Because CML is also a calibration and repair shop, Ashcroft gauges, switches and transmitters can be calibrated and certified traceable to NIST, and diaphragm seal assemblies can be built and filled in-house — fill fluids include food-grade silicone, glycerin, glycol/water, Syltherm, Halocarbon and Neobee M-20.
