The optical emission spectrometer OBLF MVS1000 is used for express analysis during melting, for incoming control of metals and alloys on all bases, for technological control of workpieces, parts, etc.

The compact stationary floor-mounted multimatrix OE spectrometer based on the latest CCD detectors is designed for all standard measurements of any alloys. With its rugged design and simple operation, it is ideal for use in a factory for both incoming inspection and material inspection.

To ensure that there is no environmental influence, the detectors and readout electronics are housed in a thermally stabilized chamber. Like all OBLF instruments, electrical sparks are generated by a digital strobe generator , with the ability to easily set the best possible excitation parameters in combination with a short analysis time.

Minimal maintenance required due to open design and self-cleaning spark stand . The highlight is the patented argon supply system, optimized to keep argon consumption to a minimum, resulting in very low operating costs.
