Chronograph Chrony - Alpha Master

Manufacturer	Chronograph
Model Number	CH-16

 Chrony Chronograph - Alpha Master   The Chrony Chronograph - Alpha Master has an LCD Monitor which brings the LCD (Liquid Crystal Display) readout right up to your bench, away from the bullets path. It also doubles as a Remote Control.   Specification   The Chrony reads velocity in feet-per-second (or metres-per-second) and works in a velocity range from 30 fps to 7000 fps (10 mps to 2134 mps). Operating Temperature range: 32o Fahrenheit to 110 o Fahrenheit (0 o Celsius to 43 o Celsius), non-condensing. (Ambient temperature must be above dew-point temperature and not fall below dew-point temperature while Chrony is being used.) Storage Temperature range: 14o Fahrenheit to 120o Fahrenheit (-10o Celsius to 50o Celsius) non-condensing. (Ambient temperature must be above dew-point temperature and not fall below dew-point temperature where the Chrony is being stored, unless the Chrony is sealed in an air-tight container.)
Accuracy: 99.5% or better. Displayed velocity will not differ from actual velocity by more than 1 part in 200, i.e., ±10 fps on a velocity reading of 2000 fps. Typical performance is generally better, and shot-to-shot repeatability is always more accurate, i.e., Reported Mean Instrumental Velocity may differ by as much as 0.5% from actual mean instrumental velocity, but Standard Deviation calculated from data gathered with a Chrony will always be closer than 0.5% to actual Standard Deviation for a string. This is an important fact because an accurate measurement of a loads uniformity is of considerably more importance than is an exact measure of its average velocity.
