Light sensors for Photosynthesis & Respiration Measurement

Light Sensors

Introduction

Hansatech Instruments light sensors have been designed to provide a means of light source calibration for both the oxygen and fluorescence instrumentation product range. The Quantitherm has been designed as a method of pre-determining the incident light and temperature within the liquid-phase oxygen electrode chambers. However, please note that this unit is not designed as a submersible sensor and should not be immersed in the sample.

The QSPAR and QSRED large area quantum sensors are intended either as stand alone field portable PAR sensors or as a calibration tool for the LH36/2R (QSRED) and LS2 (QSPAR). Both units are fully cosine corrected and have analogue outputs which may be connected to an external chart recorder or data logger.

The SQS Serial Quantum Sensor has dual functionality serving first and foremost as an automatic calibration tool for the Handy PEA fluorimeter and secondly as a stand alone PAR sensor. When connected to a PC via RS232 serial communications, comprehensive Windows software allows PAR values to be logged at user defined periods for durations of up to a month.
