DEVICE CONNECTOR
Measurements straight from the instrument into the lab journal
The connector runs in your lab network, reads OPC UA instruments per LADS — curves as well as single values from balances or pH meters — and hands every finished measurement to LabNote, onto the sample and to the person working at the instrument right now.
Requires a LabNote account and an API key
Windows installer
Installs the connector as a Windows service, including the local setup page.
Download installerLinux (ARM64)
Single binary for ARM systems, e.g. a Raspberry Pi next to the instrument.
Download binaryOutbound connections only
No inbound port, no VPN into the lab. OPC UA with Sign&Encrypt and mutual certificates, read-only by default.
Signed updates
The connector reports its version with every heartbeat. Updates are signature-checked and can be switched off per installation.

Set up in four steps
- 1In LabNote, create an API key with write scope under Integrations → API keys.
- 2Install the connector on a machine or VM in the lab network (2 cores, 4 GB, outbound HTTPS).
- 3Open the local setup page, paste the API key and add device endpoints with their certificates.
- 4Register the devices under Admin → Instruments and link them to their equipment record — only then can a measurement find the person at the instrument.
Where the measurement lands
- Sample code in the upload → straight onto that sample.
- Running equipment usage → to the person and the note they are working in.
- Running worklist on the instrument → into the next open position.
- “I am measuring now” → to the person who claimed the instrument.
- Otherwise into the lab's “Unassigned” inbox.
What you can do with it
- Confirm and use it in the note.
- As a result value in a sample analysis — including the limit check.
- As the value of a worklist position.
- In chemistry via “From balance” as the actual weight.
