Welcome to Caltest Services, the service and support arm of Blue Sun Scientific. Since 1997, we have offered consulting and application support for a wide variety of NIR Instrument platforms to ensure the success of your NIR program..

Our in-house staff of FOSS™ 5000/6500 experts can repair, calibrate and monitor your NIR Instrument to ensure confidence in its results. We also offer a full range of calibration services from new calibrations, to updates and adjustments.

Although FOSS™ discontinued service and support for this very popular NIR instrument, we continue to repair, service and recondition them using our own supply of parts and personnel.


Additionally, our ongoing monitoring program includes software solutions to help with daily diagnostic checks and Sample Result management, along with regular reports on both calibration and instrument performances.
