Specifications for 3010-GWK1

Gas-Exchange Chamber 3010-GWK1

Design: Chamber consisting of an aluminum cooling block with two pneumatic connectors and transversal fan, flat polymer lid or user-designed cuvette; micro-processor controlled electronics with connectors for temperature sensors, humidity sensor, PAR-sensors, GFS-3000 or 3010-I/Box connection, power-input; cooled with Peltier-cooling units and ventilator

Measurement of chamber and ambient temperatures: Pt 100 type A, range -10 to 50 °C, accuracy ±0.1 °C. An extended version with a range from -10 to 75°C is available

Leaf temp. measurement: Thermocouple, range: -10 to 50 °C, accuracy ±0.2 °C, range of extended version: -10 to 75°C

Temperature control: Three modes of temperature control: Constant cuvette temperature, constant leaf temperature, follow ambient temperature with an offset

Temperature control range:
-10°C to 50°C depending on ambient temperature and radiative heat intake.
With 4l volume, dark: 10 K below ambient temperature and 25 K above ambient temperature.
With flat lid, dark: 20 K below ambient temperature and 35 K above ambient temperature.
Range of extended version: -10 to 75°C

Relative humidity sensor: Range: 0 to 100% r.h., accuracy: ±1.5% (5 to 95% r.h.), T90 response time (11 to 75% r.h.): <10 s

External miniature quantum sensor: Mini Quantum Sensor MQS-B/GWK1 outside of chamber. Selective PAR measurement, range 0 to 2500 μmol m-2 s-1, accuracy ±5%, cosine corrected (measuring photosynthetic photon flux density PPFD)

Internal light sensor: Selective PAR measurement, range 0 to 2500 μmol m-2 s-1 PAR, accuracy ±10%, two sensors, one in the upper and one in the lower part of the cuvette
