721N 722N 752n laboratory uv vis spectrophotometer
This series is a simple single beam spectrophotometer. The wavelength is set manually from the dial on the front panel. Direct readout of transmission or absorption on the LED display. Measured values can be transferred to PC via RS232 port for further analysis. Low price and simple design make the model tool for education or routine analysis.
