Air-Permeability Tester with Automatic Counter - OpTest

This is an automatic counter for labor saving. It counts the signal emitted every time the slit plate mounted on the inner cylinder passes the sensor. When the count reached the preset number, the device displays the elapsed time. Use of this counter with the densometer No.2060 will remarkably increase work efficiency. By setting an air volume on the preset counter, you can make measurement with a desired air volume. A printer (optional) is also available.
