RangePro 125  Rocket Motor Test Set
RangePro 125 Impulse Meter is designed for highly
convenient field testing of model rocket motors by
professionals, teachers, and advanced modelers.
This test set consists of a lightweight, hand-held readout/controller and a 50 lbf (222 N ) capacity test fixture
with a 25' extendable interconnecting cable. The rocket motor to be tested is mounted in the fixture, the
system is armed and the motor fired. After the burn and delay is complete, the Total Impulse, Burn Time,
and Delay Time is read sequentially from a large, easy-to-read digital display. Information is held until the
system is reset. The equipment is field powered by a 9 to 12V battery or by an optional internal NiCd
battery. Load cell assembly is mounted on sturdy metal base (not shown) and will easily accommodate small
rocket motors from fractional A's thru motors having up to 50 pounds thrust.
