เครื่องวัดอุณหภูมิ, ความชื้น, ก๊าซ CO, CO2 FLUKE 975

Fluke 975 AirMeter

The Fluke 975 AirMeter test tool raises indoor air monitoring to the next level by combining five powerful tools in one, rugged and easy-to-use handheld device. Use the Fluke 975 to optimize HVAC ventilation settings for ASHRAE 62 recommendations, actively monitor conditions that promote a productive environment, and quickly and accurately address occupant comfort complaints the first time.

The Fluke 975 measures:

• Temperature
• Velocity
• Humidity
• CO2
• CO

Use the Fluke 975 AirMeter test tool to:

• Respond to comfort-related calls from occupants.
• Verify the operation of building HVAC control systems.
• Determine whether adequate ventilation exists.
• Monitor air flow and velocity.
• Test for dangerous carbon monoxide leaks.
• Perform duct traversals.
• Optimize HVAC systems to manage energy costs
