Irrometer Tensiometer Test Pump Service Unit

 The Irrometer test pump service unit helps you initially setup your Irrometer tensiometer. The package comes with a green dye that will make the fluid in the tensiometer visible from a distance. 

The vacuum pump with gauge will help with removing air bubbles from your tensiometer. The gauge will allow you to see if there is a pressure leak. Air bubbles in your tensiometer can make it so the gauge gives a false, or incorrect reading.
