Handheld Colorimeter

Compact and light-weight, Amiscience's single- and dual-channel handheld colorimeter detect the optical absorption (optical density) of fixed wavelength selected from our available wavelength plans. This portable instrument provides exceptional sensitivity, repeatability, and reliability for a much lower cost compared to the market standards. Available in two different formats (mini tubes and 1-cm cuvette), this is an important device for applications in the fields of biology, chemistry, medicine, and environment. Working with proper reagents, this meter can be used to measure the concentration of specific targets, right on the spot with a simple calibration process using the touch screen. Built-in USB interface allows users to retrieve up to 80 data points for each of assay/channel. The unique dual-channel design has identical optical path for both channels, thus enabling the precise measurement of dual-wavelength absorption applications.
