Optical particle counters such as the LiQuilaz® II S05 from Particle Measuring Systems are used in a variety of environments that may experience fluctuations in ambient temperature. An additional temperature effect comes from the LiQuilaz itself, which generates heat due to warming of its internal components.
Particle Measuring Systems tested the LiQuilaz S05 particle sensor in an environmental chamber to determine if true particle counts are influenced by temperature when measuring ambient distribution of particles in water. Tests were conducted with calibration particles in order to determine the effect of temperature on sizing accuracy. The date contained herein applies to both the LiQuilaz sensors and also the LiQuilaz II sensors (released July 2017).
