Outline of the Product
Preface
Thank you for choosing our portable multi-gas monitor GX-6000 (hereinafter referred to as "gas monitor").
First of all, please check that the model number of the product you purchased matches the model number
of the product targeted by this manual.
This manual contains handling methods and specifications for proper use of this product. Not only the
first-time users but also the users who have already used the product must read and understand this
manual before using it.
Note that the contents of this manual are subject to change without notice for product improvement. Also,
any copying or reproduction of this manual, in whole or in part, without permission is prohibited.
Regardless of warranty period, we shall not make any indemnification for accidents and damage caused
by using this gas monitor.
Make sure to read the warranty policy specified on the warranty.
Purpose of use
This product is a pump suction type multi-gas monitor that enables simultaneous monitoring of up to six
different gases: oxygen in the air, combustible gas <%LEL>, toxic gases (carbon monoxide and hydrogen
sulfide), and two of gases such as volatile organic compound, sulfur
dioxide, etc. detected by the variety of smart sensors that are designed for a specific target gas
detection.The combustible gases detected by this gas monitor are general combustible gases used in
ordinary factories, oil tankers, etc., that is HC (displayed in isobutane conversion) or CH
4
(methane).
Note that detection results of the gas monitor are not intended to guarantee life or safety in any way.
The gases to be detected varies by the sensors installed in the gas monitor. Check the gases to be
detected before use and conduct gas detection properly in accordance with purposes.
Check the gases to be detected by your GX-6000 in 'Checking gases to be detected' (P. 5).

2-4. Safety information
The GX-6000 can measure maximum six gases with six sensors.
Standard unit measures four gases with four sensors for general combustible gases(LEL), Oxygen(O
2
),
Hydrogen Sulfide(H
2
S) and Carbon Monoxide(CO).
For other remaining two slots are for Smart Sensors which consist of sensor part and circuit board and are
connected with apparatus through digital signal output so various sensors. Three different types of detection
principle are applied for Smart Sensors and up to two sensors can be installed into the GX-6000.
Gas is sampled by a built-in micro pump.
Either alkaline battery pack “BUD-6000” or lithium-ion battery pack “BUL-6000” can be installed into GX-
6000.
Structure of battery unit allows end users to replace it by themselves.
It is supposed to replace the battery unit, alkaline battery, and charge the rechargeable battery at non-
hazardous area. Also, Charging BUL-6000 should be done with a specific model, BC-6000 or SDM-6000.
