CAL-KIT — complete audit kit (logger + precision sensors)
The CAL-KIT gathers, in one Explorer case, all the equipment for a compressed air system audit: the CAL-EDGE-8 logger, Rogowski current coils, a pressure transmitter, the cabling, and the CALMS Basic subscription covering five systems. It’s the turnkey solution to measure, detect losses and optimize a fleet of compressors.
Field challenge
An audit needs a logger, current sensors, a pressure sensor, the right cables — and every missing piece delays the measurement campaign. The CAL-KIT removes the assembly: everything is matched, tested and packed in a case ready to travel from one compressor room to the next.
Measurable benefits
Deploying a measurement campaign goes from days to a few hours. Current measurement with Rogowski coils is done without opening the circuits. Data rises to CALMS over LTE 4G and analysis begins while the kit is still in place. For a multi-site fleet, the same kit moves from one plant to another. ISO 50001 compliant.

Frequently asked questions
Who is the CAL-KIT for?
For plants that want to audit several compressor rooms, and for service providers who audit their clients. For a single one-off audit, an Onyx M3 audit service with our own equipment is often simpler.
Is the CALMS subscription really included?
Yes, the kit includes the CALMS Basic subscription, which covers monitoring of five systems. Higher tiers are available on request.
Do the Rogowski coils require opening the electrical circuit?
No. The coils wrap around existing conductors, without disconnecting anything. An electrician's involvement may still be required depending on your internal procedures.
