Figure 9-1.llustration of a leaf chamber: CI-301LC-2, Wide Rectangular Chamber for an open system. 

    

We recommend working in temperature ranges between 5 and 45 ºC for greatest precision. Be sure 

both

 sensors are connected to the leaf chamber prior to using. The PAR sensor is extremely sensitive 

to even subtle changes in the light environment.
