LUTRON AM-4234SD Anemometer and Humidity Meter

LUTRON AM-4234SD Anemometer and Humidity Meter

The LUTRON AM-4234SD is an advanced Hot Wire Anemometer with a real-time SD card data recording feature, designed for accurate measurement of air flow, humidity, dew point, and temperature. This multi-functional device is ideal for environmental testing, HVAC systems, clean rooms, and other air monitoring applications, providing accurate data logging and convenient analysis.

Key Features

• Dual Probes: Includes a hot wire anemometer probe for air velocity and temperature measurements and a separate humidity/temperature probe.
• Wide Air Velocity Range: Measures from 0.2 to 35.0 m/s with high precision.
• Advanced Sensor Technology: Combines a hot wire and standard thermistor for quick, accurate readings at even low air velocities.
• Versatile Measurement Units: Supports various units for air velocity (m/s, km/h, ft/min, knots, mph) and air flow (CFM, CMM).
• Humidity, Dew Point, and Wet Bulb Temperature: Monitors humidity from 10% to 95% RH and calculates dew point and wet bulb values.
• Type K/J Thermocouple Compatibility: Measures temperatures using Type K/J thermocouples for a broader range.
• Real-Time SD Data Logging: Built-in clock and calendar with adjustable sampling time from 1 second to 3600 seconds. Data is saved directly to an SD card in Excel format, eliminating the need for special software.
• User-Friendly Operation: Separate probes and a slim design make it ideal for grilles, diffusers, and other confined spaces.
• LCD Display with Backlight: Large display with green backlight for easy reading in low-light conditions.
• Power Options: Operates with six AA batteries or an optional DC 9V adapter.
• PC Connectivity: RS232/USB interface for seamless data transfer.
