‘Mini’ Fibre Optic Light Measuring System
An addition to our Fibre Optic Light Measuring Systems. A ‘Mini’ system for measuring light levels in moss, short sward, crevices, small spaces. This ‘mini’ system utilises a 2.2mm diameter fibre optic with cosine-correction. The system can be single or dual channel. The system shown is dual channel, fitted with filtering for a PAR Quantum [...]
2 & 4 channel Light Sensors
Specialised sensors for those who need to measure reflected as well as incident light at two or four different wavelengths. These units can be used either with or without the cosine collecting adapter in place on top of the sensor. Clearly with the adapter in place the light measured by the two or four channels [...]
Single Channel Light Sensor – custom
We are able to consider building a single channel light sensor with user specified wavelengths between 400 and 1000nm. Please do not hesitate to contact us and enquire. Download datasheet: 1 Channel Custom Sensor
‘Standard’ Fibre Optic Light Measuring System
A one or two channel radiometer with a long fibre optic probe extension. The light is collected from the tip of the probe at right angles to its long axis. Thus the probe can be inserted in short grass sward and collect down-welling light. The filters and diodes are housed in a small ABS box, [...]
Sensors for the Hansatech Leaf chamber
A sensor designed especially for use with the leaf chamber produced by Hansatech Ltd. There is a choice of two spectral responses – the standard Quantum response (SKP 216Q) and a 550-750nm response (SKP 216ER) to match the LEDs used for leaf illumination.
Red / Far-Red Sensor
A 2-channel sensor with narrow band filters centred at 660nm and 730nm. A very popular filter combination important for plant phytochrome studies, and controlling plant responses in mixed lighting conditions.
UV sensors
UVA (SKU 420) UVB (SKU 430) UVI (SKU 440) Three sensors designed to measure the UVA (315-400nm) and UVB (280-315nm) parts of sunlight, plus a UVI sensor designed to match the erythema curve. Components used have been selected for their stability in a UV environment. The bandwidth characteristics are tailored to the ISO standard.
Sensors for remote sensing
Sensors for remote sensing. We offer 2 and 4 channel fixed band sensors with filtering from 400 – 2400nm to suit your application. Narrow band or wide band wavelengths.
Pyranometers (solar radiation)
For measurement of total sunlight and for use in outdoor locations we offer the silicon cell Pyranometer, A very popular and cost effective sensor, which is calibrated against a WMO Secondary Standard Thermopile. Output is proportional to total solar energy in watt.m-2.
PAR Sensors
PAR Quantum PAR ‘Special’ PAR Energy These sensors are traditionally used in plant growth studies. We can offer waterproof models suitable for long term exposure and underwater applications, and splashproof models of the PAR Quantum & PAR Energy suitable for glasshouses, plant growth cabinets, etc. The PAR Quantum is the sensor with the ideal 100% [...]
