The C-7100 and C-7200 series are UV-Vis spectrophotometers designed for laboratory measurements of absorbance, transmittance, and concentration. The C-7100 operates with a single beam optical system, while the C-7200 uses a double beam optical system; both series offer S and A variants with different spectral bandwidth options.

The instruments cover the 190-1100 nm wavelength range, providing ±0.3 nm wavelength accuracy and %0.2T photometric accuracy. The 7-inch color LCD display and silicon buttons enable operation without a computer; USB storage allows data transfer in Excel, txt, and image formats. RS232 and USB (A/B) ports support printer and PC connectivity.

User-replaceable socket-type tungsten-halogen and deuterium lamps (up to 2000 hours) with automatic operating time recording. The 1200 lines/mm holographic grating and silicon photodiode detector deliver stable and reproducible measurements. An ideal choice for general chemistry, biochemistry, and quality control laboratories.

Frequently Asked Questions

What is the difference between the C-7100 and C-7200 series?

The C-7100 features a single beam optical system, while the C-7200 uses a double beam optical system; double beam systems provide higher stability in reference measurements.

What is the difference between S and A variants?

Standard models have 2nm spectral bandwidth; S models offer 1nm bandwidth, while A models provide selectable bandwidth options of 0.5/1/2/4nm.

Can the instrument be operated without a computer?

Yes, the 7-inch LCD display and silicon buttons allow testing without computer connection; data can be transferred via USB.
