Semicaps STM32 Sample Thickness Measurement
Used but in good condition. This unit powers on and the display is sharp and bright. I can change the readout numbers that show on the display by pushing the buttons. I can see the small laser light beam in the center of the small block that is under the light head. I am not able to test it any further. I do not know when this unit was last calibrated. The label shows Voltage 100-230.
