The Sper Scientific Hybrid-Powered

Environmental Quality Meter 850068 is a 4

-in-1 instrument that functions as a:

 Light Meter—measures light using an

exclusive photodiode and color-

correction-filter, light sensor. Meets the

Commission Internationale de

l’Eclairage (CIE) photopic standards.

 Anemometer—measures wind-speed

using a low-friction, ball bearing wheel

design to provide exceptional accuracy.

 Hygrometer—measures relative

humidity using a high-precision

humidity sensor with fast response

time.

 Thermometer—measures temperature

using standard Type-K (NiCr-NiAl)

thermocouple input jack for all Type-K

probes (optionally available).

The rugged, light-weight and portable

design of the Environmental Quality Meter

allows you to use it almost anywhere to

monitor elements and maintain a healthy

and safe environment.

The Hybrid-Powered Environment Quality

meter also offers a Green power source

through a built in hand-crank generator,

enabling battery-free operation.

Recommended exposure limits for the

various elements have been set through

government organizations such as the US

Occupational Safety and Health

Administration (OSHA) and the National

Institute for Occupational Safety and

Health (NIOSH).

Current recommendations and guidelines

are available through these organizations,

as well as many others. (Refer to

Environment References page 27.)

Nautical miles per hour

Relative Humidity Measurement Units

Relative humidity (RH) is a term used to

describe the amount of water vapor that

exists in the air and displays as a

percentage.

Temperature Measurement Units

°C/°F Represents the temperature in either

Celsius or Fahrenheit degrees.
