Handheld Colorimeter

Compact and light-weight, W2 Optronics’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. Only requiring 250µL of sample size, 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 the three assay settings.
