Compatible with DW2/2, LD2/3 & DW3 (with suitable adapter) electrode chambers.

Max. intensity up to 1200 µmol m-2 s-1 (in DW2/2). Requires OXYL1 control unit for automatic control of intensity changes.

High Intensity light housing with 36 red LED’s centred on 650nm.

Compatible with DW3, LD1/2 & LD2/3 electrode chambers. Max. intensity up to 900 µmol m-2 s-1 (in DW2/2).

Requires OXYL1 control unit for automatic control of intensity changes.

High intensity 100W tungsten halogen light source (50W option available).

Max. intensity up to 1800 µmol m-2 s-1 in gas-phase electrode chambers. Mains powered stabilised power supply. Integral optics provide minimum intensity variation across beam & little divergence from parallel.

Integral infrared reducing Hot-Mirror filter. Mounting slots allowing addition of filters for intensity attenuation or spectral modification. Fibre-optic adapter allows connection of A8 fibre-optic cable in order to increase max. intensity to 8000 900 µmol m-2 s-1.

Quantitherm Light Meter Thermometer (QRT1).
The QRT1 Quantitherm light meter thermometer is specifically designed for measurement of incident PPFD and temperature inside the reaction chamber of liquid phase (DW1, DW2 and DW3) oxygen electrode units which are commonly used during respiration and photosynthesis studies.

PAR sensor with large dynamic range (0 - 50,000 µmolm-2s-1).
0 - 50°C thermometer with 0.02° resolution.

Dual digital display of light and temperature with °C / °F selection. Voltage output signal via analogue output cable for logging / chart recording. 0 Direct signal input into Oxylab oxygen electrode control unit.

PAR Waveband Light Sensor Large area quantum sensor & matched display unit. Measures PAR waveband radiation (400 - 700nm) at leaf surface in LD1/2 and LD2/3 gas-phase electrode units. Voltage output signal via analogue output cable for logging / chart recording.

Red Waveband Light Sensor (QSRED) QSRED incorporates all the features of QSPAR except that it is filtered for red waveband radiation (550 - 750nm).
