Overview:
Test the velocity or your Air Rifle in mps, and measure energy in Joules. This Chronograph works perfectly in any light setting, even in the dark!
No more cursing at your chronograph because you can’t get the lighting right. 8)
Saves up to 40 shots, which can be reviewed on the Chronograph after shooting. Comes with a tripod for easy shooting setup.
Features:
12 sets of infrared sensor heads before and after, to avoid leak detection
Four-sided hollow design to prevent airflow interference
Simultaneously record 40 sets of speed and kinetic energy data for easy viewing
Large channel: 46*68mm
Reference parameters
Working voltage: DC3.7-4.2VAlready builtlithium battery)
Working environment temperature: -30 ~ +60
Accuracy: test error≤1%
Measuring range: 1-800 M /S (also can toggle the settings to fps)
Other: the four sides of the hollow design, not only visual field, but also to alleviate the impact of airflow measurement. Improved stability and accuracy of the test.To measure the velocity of the projectile propelled by the air pressure, please measure the distance from the machine 4-8 cm, so that the air flow can be disturbed to get stable and accurate data
Function: velocity measurement /Speed energy/ Look through records
Package included:
1 x Speed Meter
1 x Tripod(Optional)
1 x USB Charging Cable
So far so good. I didn't have time to play with it very long but it seems like the MPS is working great. Unfortunately the instructions are all in chinese...you could also try to teach quantum mechanics to a rat (you lost a star there). Will have to contact the seller about that since I can't seem to find how to switch that to other features. Otherwise for the price it's fine and realy works in the dark ! :D
