J457 Computer Bridge
Many users are happy to use their own computer to control laboratory equipment. It does not suit all applications, but it does offer some advantages:
- A PC that is made by the millions to a commercial standard, is always going to be much cheaper than a controller made by the hundreds to an industrial standard.
- It allows the users IT department greater control over updates, exporting and backups


The CB can be added to all OM versions of the J457; this includes the EP (picturedabove), DP, CP and CC.
There are two versions of the Computer Bridge. CB allows the optics of the J series refractometer to be operated from an external PC using Windows 10 or later. CBS provides the same function, and includes a Microsoft Surface.
