Product List

Each set of temperature probes contains 1-6 pairs of thermocouple sensors. The probes are made from Teflon or stainless steel. We will build customized probes with sensors placed at a depth of 5 to 55 mm. The standard cable is 5 m long and it is terminated with either a 9-pin or a 15-pin D-plug.

Sap flow sensors

Heater probes are made from either 1.4 mm or 1.8 mm diameter stainless steel tube. The heater length can vary from 20 mm to 70 mm depending on the tree size. The standard heater cable is 5 m long and it is terminated with banana plugs.

Heater probes

Power to the heater is delivered via a simple heat pulse controller. A single controller can switch up to 3 heaters at a time. These are activated  by a Campbell logger using a simple 5V TTL pulse (c1-c8).

Heat pulse controller

The standard signal cables are 5 m long. Extension cables of up to 30 m can be added to the system. These cables are terminated at each end using 9-pin or 15-pin D-sockets.

Extension signal cables

The standard power cable is 0.5 m. Extension cables of up to 30 m can be added to the system. One power cable can connect to many controllers.

Extension power cables

The standard installation includes a cork borer, to remove bark, a drill guide, three long-series drill bits and two  ‘blank’ temperature probes.
