Single Beam Visible Spectrophotometer – YR01844

Manufacturer: Kalstein

Certificacion europea


With microprocessor controlled, YR01844 could realize Auto Zero and Auto 100%T adjustment with one push-button. YR01844 has a LCD display instead of LED display for direct readout of Transmittance, Absorption and Concentration.

Grating monochromator

1200 line grating ensures high resolution, high accuracy and low stray light.

Data output

YR01844 is equipped with USB port which can be connected to PC to edit date through specific software.Date can also be printed through a parallel port when connected to a micro printer

Compact design, easy to carry

The compact design of YR01844 saves bench space while all components function remain performed like 120mm wide sample compartment and long optical path monochromator.

Four Display Mode

YR01844 can display absorption,transmittance,concentration and coefficient directly by different mode switching.
