Cylinder for testing the Renco backfat measuring device

Directions for use:

• Wet the end of the probe or the cylinder and introduce the probe in the cylinder.
• The opposite end of the cylinder must not come into contact any surface, and the hole of the cylinder must not be covered.
• The reading must be approximately 25 mm, depending on the humidity, and approximately 30 mm for the devices purchased in Australia and New Zealand.
• The real reading figure is not as important as obtaining a reading.
• In case of any problem most probably a reading will not be obtained.
