Biospherical Instruments has been making instruments since 1977. Every instrument comes to the end of its useful lifetime, usually because we can no longer obtain parts to service the instrument. Some instruments may still work perfectly, but if our calibration laboratory has not seen any instrument of its type for several years, upgrades to the calibration facility may mean that even a simple calibration is much more time consuming (and expensive) than it once was.
Below is a table of unsupported instruments, the latest information on whether calibration and servicing are still available, as well as possible replacement instruments.

Note 1. An internally recording microradiometer-based instrument is under development. We are particularly interested in learning the features that our customers would like in such a product. Please contact Biospherical for details if you are interested.
Note 2. Analog panel meters are no longer available. Some other repairs may still be possible.
Note 3. See the BSI Application Note for running this instrument with Win7 desktops and laptops.
