1. Description
Sampling type Gas Detector (SI-H100) measures sample gas by sensor cartridge in the case upon
suction remotely on a real time basis. It is a device that assists to prevent or control a variety of gas
related accidents including suffocation, intoxication, fire, explosion, corrosion, and so on in multiple
semiconductor or industrial sites.
SI-H100 measures the gas concentration on a real time basis constantly and shows alarm of
dangerous concentration, fault situation, and so on, upon attaching on the wall.
By operating four buttons in the lower part of the screen, environmental setting of the device can
be easily amended.
Measured gas concentration is transmitted with 4-20mA output on a real time basis and external
operations according to the desired situations can be variously organized by three internal relays.
In addition, it is possible to output MODBUS/TCP, and to solve data transmission and power at the
same time only with a LAN cable (PoE).
WARNING
Please be aware of the manual before using the device. This device
should be used and maintained according to the instruction and it may
cause the damage of the device, or the user’s injury or fatality in case not
to conform the instruction.

2. Product composition
SI-H100 consists of four parts including case, sensor cartridge, main frame, and prob for installation.
Also, it contains the accessary of thermal decomposition module(Pyrolyzer) to be used upon
additional purchasing to be able to detect and measure the gas by thermal decomposition in case
of the materials without gas sensor such as NF3.
