Mini Environmental Quality Meter (3 Parameters)

Sper Scientific 850025 Mini Environmental Quality Meter (3-in-1)

Meet the Sper Scientific 850025, a compact and versatile environmental quality meter designed for simplicity and accuracy. This lightweight, pocket-sized device allows for easy one-handed operation, making it an indispensable tool for a wide range of professionals and enthusiasts. It is perfect for scientists, agricultural specialists, facilities managers, HVAC professionals, home inspectors, field technicians, health and safety personnel, hazmat crews, outdoor enthusiasts, educators, and coaches—anyone who needs reliable environmental data to make crucial decisions.

Key Features and Functions:

This multi-parameter meter delivers precise readings for three essential environmental conditions:

1. Wind Speed (Anemometer): Measures airflow with high sensitivity, detecting speeds as low as 0.4 m/s. It offers multiple units of measurement (ft/min, m/s, km/h, MPH, knots) with an accuracy of ±3% full scale up to 20 m/s. The snap-in anemometer vane is easily replaceable, ensuring long-term usability.
2. Air Temperature (Thermometer): Provides accurate temperature readings in both Fahrenheit and Celsius, crucial for assessing comfort, safety, and operational conditions.
3. Relative Humidity (Hygrometer): Measures moisture content in the air, essential for monitoring environments prone to mold, static electricity, or other humidity-related issues.

Designed for Field Use:

The 850025 is engineered for convenience and durability in any setting. All models in this series feature a large, clear display with a backlight for low-light conditions, a data hold function to freeze readings, and a min/max feature to track fluctuations over time. The meter comes as a complete kit, including a protective carry pouch, a secure wrist strap, and a button cell battery that provides at least 40 hours of continuous use.
