Our Equipment

Unfortunately valuable urban trees are often removed without need. Our specialist equipment, alongside a tree risk assessment, can give you peace of mind. This helps you to understand and manage the risks better. Then you will be able to keep and maintain your trees long into the future.

IML Micro Drill Resistograph - equipment used by Purearb technical arborists Christchurch
IML Micro-Drill
(Resistograph)

The IML-RESI F-Series wood testing system measures internal wood resistance.

PiCUS Calliper - equipment used by Purearb technical arborists Christchurch
The PiCUS Calliper

The PiCUS calliper is an instrument for precisely measuring the geometry of the tree.

PiCUS Sonic Tomograph - equipment used by Purearb technical arborists Christchurch
PiCUS Sonic Tomograph Result

The results are represented as solid wood, illustrated as brown, partially damaged which is shown as green, and decayed wood, which illustrated as violet and blue on the PiCUS image.

The readings are normally taken on the four cardinal points around the circumference of the tree.

Transmission Hammer - equipment used by Purearb technical arborists Christchurch
Transmission Hammer

The hammer transmits sound waves across a horizontal plane and detects differences in the ability of the wood to transmit acoustic waves.

PiCUS Tree Motion Sensor 3 - equipment used by Purearb technical arborists Christchurch
PiCUS Tree Motion Sensor 3

PiCUS Tree Motion Sensor 3 measures the tree's natural reaction to occurring winds, including all factors that influence the wind load (tree properties, exposition, wind speed).

IML result Printed on a Wax Strip

By pairing the Tree Condition Survey with an IML tree inspection tool, our company can interpret the internal health of the subject tree(s).

PiCUS Q73 software - equipment used by Purearb technical arborists Christchurch
PiCUS Q73 software

The Q73 software produces two-dimensional images of the tomogram results.

A root plate tilt of 0.25° or more at wind gust speeds of 50 km/h will inevitably lead to excessively high tilt angles at higher wind speeds, and the tree can no longer be considered safe.
