INTRODUCTION

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 color­correction-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).

INTRODUCTION

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.)
