A nephelometer [1] or aerosol photometer [2] is an instrument for measuring the concentration of suspended particulates in a liquid or gas colloid. A nephelometer measures suspended particulates by employing a light beam (source beam) and a light detector set to one side (often 90°) of the source beam.
It is performed by measuring the scattered light at an angle from the sample being measured. [2] In diagnostic nephelometry, the ascending branch of the Heidelberger-Kendall curve is extended by optimizing the course of the reaction so that most plasma proteins’ (from human blood) measurement signals fall at the left side of the Heidelberger ...
Instrument sterilizer: to sterilize instruments in absence of an autoclave: Kidney dish: as a tray for instruments, gauze, tissue, etc. Measuring tape: for length, height, head circumference and girth measurements Medical halogen penlight: to see into the eye, natural orifices, etc. and to test for pupillary light reflex, etc. Medical ultrasound
Instrument Uses Flow cytometer: used for automated cell counting as in total blood count, differential count, etc. Tissue bath or organ bath or Dale's apparatus: used in full tissue experiments, for example using guinea pig ileum mainly used in pharmacology for application of drugs to these tissues.

In the past, a common time measuring instrument was the sundial. Today, the usual measuring instruments for time are clocks and watches. For highly accurate measurement of time an atomic clock is used. Stopwatches are also used to measure time in some sports.
Smartwatches and rings that claim to measure blood sugar levels for medical purposes without piercing the skin could be dangerous and should be avoided, the U.S. Food and Drug Administration ...
The propensity of particles to scatter a light beam focused on them is now considered a more meaningful measure of turbidity in water. Turbidity measured this way uses an instrument called a nephelometer with the detector set up to the side of the light beam. More light reaches the detector if there are many small particles scattering the ...
