The ΔLA-B (ΔT Leaf-to-Air-Broadleaf type) is a highly precise sensor for continuous measurements of temperature differences between leaf surface and ambient air. The signal is captured by means of a very thin chain (10-fold) of thermocouples. Distributed over the leaf surface, multiple measurement points are directly touching the leaf surface, providing a spatially integrative temperature signal. Designed for broad leaves, the sensor is mounted at the leaf with a light-weight wire frame.

Advantages

  • Precise and continuous measurement of leaf-to-air temperature difference

  • Multiple measurement points distributed over leaf surface, spatially integrative sensor signal

  • Sensor output in mV, recordable with most of the common data loggers, no calibration is needed for signal transformation in °C

  • Minimal load on the target, no injury to plants

  • Installation resistant against wind and rain

  • Leaf size and shape specific ordering possible

Limits

Not suitable for leaf sizes smaller than 3 cm

Delivery

  • Complete with 5 m cable

  • Fixing materials and installation tools

Options / Ordering Information

  • Cable extension (50 m max, please specify in meters)

  • If necessary, adjustments for different leaf sizes and shapes are possible

  • Data Logger with integrated light, air humidity and air temperature sensors.
