The ΔLA-C (ΔT Leaf-to-Air-Conifer type) is a highly precise sensor for continuous measurements of temperature differences between conifer needle surface and ambient air. The signal is captured by means of a very thin chain (10-fold) of thermocouples. Designed for conifer needles, the sensor with its multiple measurement points is directly attached to different needles, providing a spatially integrative temperature signal.

Advantages

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

  • Multiple measurement points, 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 needles shorter than 3 mm

Delivery

  • Complete with 5 m cable

  • Fixing materials and installation tools

Options / Ordering Information

  • Cable extension (50m 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.
