EXTECH EN100 11-in-1 Environmental Meter

Mike — Sat, 27 Feb 2016 06:30:25 +0000

Extech EN100 11-in-1 Environmental Meters (with Light sensor).

11-in-1 Environmental Meters (w/Light sensor). Built-in sensors measure 11 environmental conditions including Air Velocity, Air Flow, Temperature, Humidity, Wet Bulb, Dew Point, Heat Index, Wind Chill, Barometric Pressure, and Altitude

Pocket-Sized All-in-One Environmental Meter Has You Covered
The Workplace Challenge: Job site environmental problems are not only a source of complaints from workers, they can have a negative impact on product/service quality and the bottom line. Employees who are uncomfortable are typically less productive, unhappier with their jobs, and prone to higher rates of absenteeism and turn over. Show your employees that you take safety and health issues seriously. Impress them by investigating complaints and inquiries with the right tools. The Extech EN100 is a powerful and innovative meter that joins together the following diagnostic capabilities: – Anemometer: Measure air velocity/air flow at vents and registers before and after repairs to ensure adequate fresh/conditioned air supply – Humidity Meter (Hygrometer): Measure humidity levels to check HVAC systems are dehumidifying adequately during high humidity periods, and to identify static hazards due to dry air. – Thermometer: Quantify potentially hazardous temperatures (coupled with humidity levels) especially in outdoor worksites such as construction and farming jobs or hot indoor jobs with basic fan-based ventilation. (You can even connect an external RTD probe for added temperature measurement flexibility.) – Light Meter: Ensure adequate lighting to ease eye strain for visual-intensive jobs reading labels in warehouses, QC’ing products, etc. And, the display automatically rotates when the meter is held upside-down for light readings. One rugged instrument and the right tool is always within reach! Freeze readings with the Data Hold function and light up the display with the LCD’s backlight in poorly lit areas.

Measure & calculate 11 different environmental readings:

Air Velocity
Air Flow
Temperature
Humidity
Wet Bulb
Dew Point
Heat Index
Wind Chill
Barometric Pressure
Altitude
Light Levels

Who Uses the EN100?

Occupational safety officials
Facilities maintenance
HVAC/R professionals
Indoor Air Quality (IAQ) technicians
Apartment/condo property managers
Building/home inspectors
School department/collegeplant/dormitory maintenance
