BRT-5200V Visible Spectrophotometer

The BRT-5200V Visible Spectrophotometer is an advanced benchtop analytical instrument engineered with a high-performance Czerny-Turner (C-T) monochromator optical architecture, a 4.3-inch color touchscreen LCD, and a high-sensitivity silicon photocell detector. Designed for chemical processing laboratories, environmental testing stations, agricultural research centers, and food safety inspection facilities, it delivers high optical purity and precise photometric performance across the 325 nm to 1100 nm spectral range with a narrow 2 nm spectral bandwidth, ±1 nm wavelength accuracy, and ≤0.5 nm wavelength repeatability.

Powered by a long-life 20W/12V tungsten halogen lamp (rated for 2,000 hours) and a 1200 lines/mm holographic grating, this reliable Visible Spectrophotometer achieves excellent transmittance accuracy (±0.5%T) and reliable quantitative linearity. Equipped with dynamic touchscreen controls, automated startup wavelength calibration, onboard memory for 200 datasets and standard curves, real-time baseline monitoring, and a high-speed USB PC interface, the 15 kg BRT-5200V ensures intuitive and repeatable analytical testing workflows.

Testing Workflow & Target Applications

Standardized Testing Workflow:

1. Power on the BRT-5200V; the microcomputer system automatically performs light source checks and startup wavelength calibration.
2. Select Photometric or Quantitative mode directly using the 4.3-inch color touch screen.
3. Place a reference blank solution in the cell holder and tap the screen to execute automated 0A / 100%T baseline zeroing.
4. Load standard samples to generate a quantitative calibration curve (or input factor K and offset B), then measure unknown samples for instant concentration readout.
5. Save measurement data (up to 200 datasets) to onboard memory, transmit via USB to optional PC software, or output reports via the LPT parallel printer port.

Target Customer Applications:

• Environmental water analysis laboratories (nitrate, phosphate, COD, and heavy metal colorimetric testing).
