SC-04

Chapter 1: Introduction

Overview

This chapter briefly describes the SC-04 gas monitor. This chapter also describes the 

SC-04 Operator’s Manual

 (this document). Table 2 at the end of this chapter lists the 

specifications for the SC-04.

About the SC-04

Using an advanced detection system, the SC-04 personal gas monitor detects the presence of 

super toxic gases like HCN, PH

3

, and SO

2

. The SC-04’s compact size and easy-to-use design 

make it ideally suited for a wide range of applications, including sewage treatment plants, 

utility manholes, tunnels, hazardous waste sites, power stations, petrochemical refineries, 

mines, paper mills, drilling rigs, and fire fighting stations. The SC-04 offers a full range of 

features, including:
•

Liquid crystal display (LCD) for complete and understandable information at a glance

•

Ultrabright alarm LED

•

Distinctive audible/vibrating alarms for dangerous gas conditions and audible alarms for 

unit malfunction

•

Microprocessor control for reliability, ease of use, and advanced capabilities 

•

Data logging functions

•

Alarm trend data

•

STEL, TWA, and over range alarms

•

Peak reading

•

Built-in time function

•

Lunch break feature

•

QPS “C/US” classification for Class I, Division I, Groups A, B, C, and D hazardous 

atmospheres

WARNING:

The SC-04 detects elevated levels of super toxic gases which can be 
dangerous or life threatening. When using the SC-04, you must follow the 
instructions and warnings in this manual to assure proper and safe 
operation of the unit and to minimize the risk of personal injury. Be sure to 
maintain and periodically calibrate the SC-04 as described in this manual.

AVERTISSEMENT:Le SC-04 détecte les niveaux élevés de gaz super toxiques qui peuvent 

être dangereux ou mettre la vie en danger. Lorsque vous utilisez le SC-04, 
vous devez suivre les instructions et les avertissements de ce manuel pour 
assurer un fonctionnement correct et en toute sécurité de l'appareil et pour 
réduire les risques de blessures. Assurez-vous de maintenir et d’étalonner 
périodiquement le SC-04 comme décrit dans ce manuel.
