Probatus vs Beamex CMX
Both keep calibration records, but they were built for different jobs. This page sets out where Beamex CMX is the better choice, where Probatus is, and what to ask before deciding.
Last reviewed November 2026
The short answer
Beamex CMX is calibration management for process plants. Its strength is the link to Beamex documenting calibrators and the bMobile app: the calibrator runs the procedure and the results flow back without anyone typing them. If you own that hardware, or work in a tightly regulated plant, CMX is built for you.
Probatus needs no particular hardware. A technician reads any reference standard and types the readings into a phone, which suits a service company with mixed equipment and many customers. Results can be imported from a file or over an API, but there is no direct connection to a calibrator.
Side by side
The Probatus column describes the product as it is today. The Beamex CMX column is limited to what Beamex and public software listings say about it. Where we are not sure, it says what to ask.
| Topic | Probatus | Beamex CMX |
|---|---|---|
| Built for | Calibration service companies and field teams that calibrate instruments for customers, and backflow testers. | Plants in process industries managing and calibrating their own instrumentation. |
| Where the work is recorded | On a phone or tablet at the instrument. Readings save on the device first and sync when there is a signal. | On Beamex documenting calibrators or in the bMobile app, including offline, then transferred back to CMX. |
| Automated calibration | Readings are typed in, or imported from a file or over an API as an optional feature. Probatus does not connect to a calibrator directly and does not drive instruments. | The core of the product: procedures are sent to the calibrator and results return automatically. |
| Customers | Each instrument belongs to a customer. Customers sign in to a portal for their instruments, certificates and invoices, and can request service. | Centred on one organisation's plants. Ask how work for many external customers is handled. |
| Regulated industries | An opt-in mode adds password-checked electronic signatures. A validation package of templates, test protocols and automated test evidence is supplied for you to execute; it is not a completed validation. | Electronic signatures and data-integrity features aimed at regulated plants. |
| Decision rules and uncertainty | Simple, guarded and non-binary decision rules per job, uncertainty budgets per test point, and the reference standards on every certificate. | Calculates expanded uncertainty for each calibration point. |
| After the calibration | Supervisor approval, signed PDF certificate, work orders, invoices and QuickBooks Online. | Calibration records and certificates. Invoicing is outside its scope. |
| Licensing | Cloud by default: a subscription per technician who records work in the month, with certificates, instruments and office users unlimited. It can also be run on your own servers, which you then install and update yourself; ask us about terms. | Cloud or installed on your own server, in several editions. Ask Beamex for a quote. |
| Track record | A new product. | A long-established calibration company, widely used in process industries. |
When Beamex CMX is the better choice
- You own Beamex documenting calibrators, or plan to buy them.
- You calibrate the instruments of your own plant, on routes of many loops.
- You work in pharmaceutical or another regulated industry and need its data-integrity controls.
- You want the calibrator, the software and the transfer between them from one supplier.
When Probatus is the better choice
- You are a service company with reference standards from several makers.
- Every instrument belongs to a customer, and customers ask for their certificates and history online.
- You want customers to download certificates and request service themselves.
- You want the job to end in an invoice.
- You want to start without buying hardware or a server.
Questions to ask either vendor
- Can a technician record a calibration with no connection, and what happens to it when the connection returns?
- What is on the certificate, and can we see one produced from our own data?
- How is a correction to a reading recorded, and can the original still be seen?
- How do our customers get their certificates?
- What does it cost for our number of technicians and office staff, in a busy month and a quiet one?
- How do we get our records out if we leave?
You can test the first three on Probatus without talking to anyone: the free certificate generator and as-found / as-left sheet use the same calculations as the product.

Questions
- Do I need Beamex calibrators to use Probatus?
- No. Probatus works with any reference standard: you record which standard was used and type in the readings. It does not connect directly to documenting calibrators from any maker. As an optional feature it exports test points and imports results as a CSV file or over an API, so readings exported from a calibrator's PC software can be brought in once they are put into that layout. If automatic transfer straight from the calibrator is what you want, Beamex CMX with Beamex hardware does that and Probatus does not.
- Can I move my records from Beamex CMX to Probatus?
- Probatus imports instruments and past calibration history from Excel or CSV files, up to 2,000 rows at a time. If you can export your equipment list and calibration records from your current system to a spreadsheet, they can be brought in. There is no direct Beamex CMX importer.
- Does Probatus make a lab ISO/IEC 17025 accredited?
- No software does. Accreditation is granted to a laboratory by an accreditation body. Probatus keeps the records an assessor asks to see: readings, the standards used, uncertainty, the decision rule, who did the work and who approved it.

Calibration management software compared
Calibration software falls into a few kinds, built for different organisations. This page sorts the well-known products by who they are for, with a closer comparison of each against Probatus.
Calibration software for small labs
A lab with a handful of technicians does not need an enterprise quality system. It needs readings captured once, certificates that are right the first time and records it can find at an audit.
Preparing calibration records for an ISO/IEC 17025 audit
An assessor picks a certificate and follows it backwards: to the readings, the reference standard, the person who did the work and the procedure they used. This guide covers what that trail has to contain and how to check yours before they do.

Add a few instruments, calibrate one on your phone and download the certificate. No card is needed, and your current system can keep running alongside.
