Davis Instruments Turbo Meter - 271

The Davis Instruments Turbo Meter is a handheld wind instrument with pocket sized convenience.

Features:

• Functions include:
  • Wind Speed
• Combines uncommon accuracy, sensitivity, and pocket-sized convenience
• Based on the principle that a freely turning turbine will rotate at a speed directly proportional to wind speed
• To insure accuracy, the completely enclosed turbine is suspended on sapphire jewel bearings and its rotation is sensed by a friction-less infrared light beam
• Resulting signal is processed electronically by an LSI (Large Scale Integrated) circuit for improved reliability and reduced size
• 3-digit display provides excellent viewing contrast in bright sunlight
• Handy slide-switch selects between (4) different scales: knots, feet per minute, meters per second, and miles per hour
• Auto Power-Off: Unit automatically switches OFF after (5) minutes if no wind speed being displayed, and if the Scale Switch has not been moved
