Standard manual installation method
Introduction
The Standard manual installation method is recommended for most soil types. In this method the access
tube hole is hand augered into the soil, through and slightly ahead of the access tube. This is done using the
47.0 mm Regular Auger. The augered hole is slightly smaller than the access tube. The access tube is
fitted with a cutting edge that cuts the last of the soil away, providing a tight fit down the length of the access
tube.
This method prevents the formation of air pockets along the length of the access tube and causes minimum
disturbance to the surrounding soil profile. This installation method is proven to be the most reliable and
provides the best soil moisture data.
Items required for standard manual installations
Sentek has developed a set of installation tools specifically for the installation of their access tubes. An
installation requires:
• Sentek access tube items
• Sentek toolkits
• Miscellaneous
items
Each toolkit comes in a protective carry case. Items that look similar are marked with their measurements for
easy identification. Protective tubes are included to encase augers and other sharp tools. This protects
them in transit and prevents damage to the tool bag.
All tools required for the Standard manual installation method are contained in the Standard Access Tube
Installation Kit Complete. The tools are supplied in two carry bags.
Read through the installation method to identify the tools, cutting edges and bottom stoppers you will need
and ensure you have those tools before proceeding to the installation site.
