The holographic blazed grating monochromator has the advantages of high wavelength accuracy, good monochromaticity, and low stray light.
The new LCD screen displays clear and natural readings.
Using a microcomputer measurement system, the T-A conversion accuracy is high, and there are automatic adjustments of 0% T and 100% T, concentration factor setting, and concentration direct reading.
The measurement reading has high accuracy, good reproducibility and good stability.
Automatic light door technology, convenient operation.
