- ELI function: warning message when intense direct light is detected.
- Automatic temperature compensation (ATC).
- Calibration with water.
- Water resistant (IP65).
Fast and continuous measurements with non-homogenous samples. Once the start key is pressed, measurements are taken every second. Different samples of liquids of similar concentration and of minimum viscosity can be measured one after another.
- With prism head (IP67), sleek prism housing design for easy cleanup.
- The Brix (%) will be displayed in approx. 2 s, continuous measurements allow displaying the current value each second.
- ZERO key to perform zero-setting.
- With strap holder, battery case cover and LCD display.
Like PEN-PRO but with scale.PEN-URIN S. G.:
Messures the specific gravity of urine in samples.
- After pressing the start button, the value will be displayed in approx. 2 s.
- With storage case.
