PerfectFlite StratoLogger CF

This versatile, easy to use altimeter audibly reports your rocket``s peak altitude and maximum velocity after flight via a sequence of beeps. Two outputs are provided for deploying a small chute at apogee to minimize drift and a larger chute closer to the ground to slow your rocket for a gentle touchdown. Main chute deployment altitude is adjustable from 100 feet to 9,999 feet in 1 foot increments with the computer interface or 100 foot increments without. Nine user-defined presets make changing the settings in the field quick and easy.

The StratoLogger collects flight data (altitude, temperature, and battery voltage) at a rate of 20 samples per second throughout the flight and stores them for later download to a computer. It retains data from the most recent 31 flights (up to 9 minutes per flight) even with power removed. The optional DT3U data transfer kit includes software for graphing and printing a wide range of characteristics including altitude, velocity, and more.

As its name implies, the StratoLogger is capable of recording flights of up to 100,000 foot altitude (well into the stratosphere) with industry-leading precision and accuracy.

Features

  • Works to 100,000 feet MSL, audibly reports peak altitude and maximum velocity after flight.
  • Stores 31 flights of 9 minutes each (altitude, temperature, and battery voltage at 20 samples per second) for download to a computer with the optional DT3U USB interface. Data are preserved with power off.
  • Deploys drogue and main chutes with audible ematch continuity check.
  • Outputs capable of 10A current for 1 full second to allow use with nearly any ematch or ematch substitute. Reverse polarity protection prevents spontaneous firing if battery is connected backwards.
  • Main chute deployment altitude is adjustable from 100 feet to 9,999 feet in 1 foot increments. 9 presets allow for quick change in the field.
  • No mach delay necessary for mach+ flights: Automatic MachLock assures proper operation with any flight.
  • Brownout protection will tolerate 3 second power loss in flight - no need for multiple batteries.
  • Precision sensor &;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; 24 bit ADC yield superb 0.1% accuracy.
  • Built-in voltmeter reports battery voltage on powerup - no more guessing about battery condition.
  • Audio connector for optional amplified external beeper or LED.
  • Post flight locator siren aids in locating your rocket. Especially useful when combined with amplified external beeper.
  • Confusion-free individual terminal blocks - unreliable multiple wires per terminal are not necessary.
  • Pressure sensor is immune to false triggering from exposure to sunlight.
  • Highly resistant to false trigger from wind gusts tested in 100+ MPH winds!
  • Selectable apogee delay for dual altimeter setups prevents overpressure from simultaneous charge firing.
  • Low power design runs for weeks on a standard 9V alkaline battery. Post- flight locator siren will run for months, giving you multiple "second chances" to find a lost rocket.
  • Telemetry output for real-time data in flight with your RF link.
  • Rugged SMD construction, stringent QC testing, and internal self-diagnostics assure uncompromising reliability.
  • Wide operating temperature range of -40F to +185F.
  • Measures just 2.75"L x 0.9"W x 0.5"H, fits 24mm tube, weighs just 0.45 oz.
  • Backed by full three year warranty.

PerfectFlite PNut Altimeter

A peanut-sized altimeter with super-sized features! This tiny, easy to use altimeter audibly reports your rocket``s peak altitude and maximum velocity after flight via a sequence of beeps. A post-flight warbling siren sound makes finding small rockets in tall grass easier.

The Pnut collects flight data (altitude, temperature, and battery voltage) at a rate of 20 samples per second throughout the flight and stores them for later download to a computer. It retains data from the most recent 31 flights (up to 9 minutes per flight) even with power removed. The optional DT3U data transfer kit includes software for graphing and printing a wide range of characteristics including altitude, velocity, and more.

Despite its small size and low price, the Pnut is capable of recording flights of up to 100,000 foot altitude with industry-leading precision and accuracy.

A built-in Lithium Polymer rechargeable battery will run the Pnut for up to 100 hours between charges.

Features

  • Works to 100,000 feet MSL, audibly reports peak altitude and maximum velocity after flight.
