• Accuracy: +/-(5% of reading+20) ft/m; +/-(5% of reading+0.1) m/s
• Air volume measurement range (Units): 0 to 99999 (CFM, CMM,CMH, l/s)
• Air temperature measurement range: 14.0 - 122.0°F (-10.0 - 50.0°C )

The Triplett AM500 Hotwire Anemometer uses a strong and precise airflow and temperature sensor to provide very accurate readings. The compact telescoping probe head is ideal for ductwork. This micro-processor based design includes ATC (Automatic Temperature Compensation) and allows for accuracy on low flow (30ft/min) applications where traditional vane anemometers do not. It is a must have for any HVAC Engineer or Technician. Complete with telescoping probe with magnet, O-ring marker, hard carrying case and four 1.5V AAA batteries.

• Robust hot wire sensor for accurate value and long sensor lifetime
• 8mm diameter probe head with 1m long telescopic tube; Enclosed with O-ring to mark the depth of the duct
• Telescopic tube with alignment marking to show the correct air-in direction for accurate measuring
• Non-slip ergonomics rubber grip
• Metric and Imperial selectable units
• CFM, I/s, CMH, CMM
• Low battery indicator
• Display modes include: Normal, Min/Max, Time Average, and Point Average
• Hold function freezes current readings; Sleep and non-sleep selectable
• Backlit for dark places
• Powered by (4) AAA batteries
