3010-DUAL

Accessory

DUAL-PAM-100 and DUAL-KLAS-NIR Gas-Exchange Cuvette

  • Overview
  • Specifications
Gas-Exchange Cuvette 3010-DUAL mounted on a linear positioning system

To combine chlorophyll fluorescence and NIR measurements with gas exchange measurements using the WALZ GFS-3000 gas exchange system, we have developed the DUAL-PAM-100 and DUAL-KLAS-NIR gas-exchange cuvette (3010-DUAL).

Design
Cuvette is a sandwich of two 2 x 2 cm aluminum frames, each holding the end part of a Walz standard Perspex rod to connect various measuring heads of the DUAL-PAM-100 or DUAL-KLAS-NIR. Distance between Perspex rod and leaf: ca. 1 mm on each leaf side.
Pneumatically separated upper and lower cuvette halves. Controlled by a regulator unit with sockets for cable connections to the Control Unit 3000 C of the GFS-3000 and a trigger input line.
Cuvette temperature
Pt 100 type A (located near the Peltier elements), range -10 to 50 °C, accuracy ±0.1 °C
Temperature control
Set point value for cuvette temperature. Cuvette temperature ranging from 10 degrees below ambient to max. +50 °C
Leaf temperature measurement
Thermocouple, range -10 to 50 °C, accuracy ±0.2 °C
External miniature quantum sensor
Mini Quantum Sensor MQS-B/GFS: Selective PAR measurement, range 0 to 2500 μmol m-2 s-1 PAR, accuracy ±5%, cosine corrected
