3. INTRODUCTION
3.1. Monitor Overview
Protégé SG is a reusable gas detector designed to monitor different hazardous gas levels. With
one-button activation, a direct reading segment LCD, and bright LEDs, Protégé SG is simple to use.
Due to its small size and light weight (5.3 oz.), the monitor is comfortable to hold and handle. All fil-
ters, lithium batteries, alligator clips and sensors are field replaceable.
The monitor contains a data log for 5000 events and records STEL/TWA/PEAK exposures, calibra-
tions, and gas values. An IR connection allows quick parameter configuration, monitor calibration,
and event log retrieval via the Portable Gas Detection (PGD) Application Software.
