| These meters are light weight, tiny in size with simple, one-hand, operation. They are perfect for scientists, agricultural specialist, facilities managers, HVAC professionals, home inspectors, field technicians, health and safety personal, hazmat crews, outdoor enthusiasts, educators, and coaches … all of whom need accurate information to properly access environmental conditions and make crucial decisions. All units read air speed in addition to the wide selection of environmental parameters detailed above. Will sense airflow as low as 0.4 m/s with an accuracy of ±3% (4% >20m/s). Replaceable snap-in anemometer vane is available. All models feature min/max, hold, a backlight and come complete with a wrist strap, carry pouch, and button cell battery providing at least 40 hours of continuous use. Basic Meter- 850025 Is the most basic Mini-Environmental Meter in the Sper Scientific product line. This meter is capable of measuring three (3) different environmental parameters. With this meter you can measure: Wind Speed, Air Temperature, and Relative Humidity (RH). Intermediate Meter- 850026 Is capable of measuring seven (7) different environmental parameters. With this meter you can measure: Wind Speed, Air Temperature, Air Volume, Relative Humidity (RH), Wind Chill, Heat Stress Index, Dew Point, and Wet Bulb. Advanced Meter- 850027 Is the most robust Mini-Environmental meter in our line. This meter measures twelve (12) different parameters: Wind Speed, Air Temperature, Air Volume, Relative Humidity (RH), Wind Chill, Heat Stress Index, Dew Point, Wet Bulb, PT 100 ohm (with optional probe), Barometric Pressure, Altitude, and Visible Light. Model 850027 accurately measures liquid and solid temperatures using the optional Pt 1000 penetration probe. Dimensions: 4¾" × 1¾" × ¾" (121 × 44 × 19 mm) Weight: 2 oz (57 g) |
