Manufacturer: Ai Electronics Engineering Co., Ltd.
Model: VSM-20

Features

Multi-Environment Measuring Instrument

• Expanding applications with additional probes.
  No settings required due to interchangeable automatic recognition probes.
  • S-411 Sensor: Wind speed, Temperature
  • S-413 Sensor: Humidity, Temperature
  • S-414 Sensor: Pressure
• The probe has a built-in telescopic mechanism, allowing it to extend freely up to approximately 1,000 mm.
• 180° rotatable sensor tip. Measurements can be performed correctly by adjusting the angle of the probe, either by suction or by blowing.
• Both integrated and detachable types are available for the probe and main unit. The sensor probe can be combined with the main unit for one-handed operation.
• Supports analog output.
• Compliant with JIS standard T8202.

Applications

● Building air conditioning facility management (from office buildings to schools, museums, etc.)
● Air conditioning management for clean rooms and greenhouses 
● Factory comfort and energy saving management 
● Indoor environment measurement
