All I know is it is a Quick Check 4 beam ratiometric nephelometric turbidity concentration counter. It counts the concentration of particles in solution in M/mL. I don't really know much more about, I recently purchased the unit and have just started using it.


Raising the lights was the trick! I have always been so concerned with keeping the lights as close as possible to maximize growth and minimize stretching. I really did not feel much heat holding my hand under the light for a few minutes, and the min/max thermometer had a range of 75-79°F. Either way, once I raised the lights to an average of 15" from the smaller plants, they all took off in growth and seem much happier. Thanks for the tips!
