The Sensit®Gold CGI is designed to detect combustible gases,
oxygen content and toxic gases when so equipped with the
available sensors. Each model of the Sensit®Gold CGI pro-
vides specific detection features based on available sensor op-
tions. Each Sensit®Gold CGI can be re-configured or upgraded
by the manufacturer for an additional charge should your sens-
ing requirements change. Consult Sensit Technologies for a list-
ing of new sensors available for use with the Sensit®Gold CGI.
Sensit®Gold CGI instruments incorporate an advanced low
power semiconductor sensor to measure combustible gases in
the LEL (Lower Explosive Limit) range and a thermal conductiv-
ity style sensor to measure combustible gases in the percent
volume range. The user may select either methane or propane
gas readings from a user menu depending on the sensing re-
quirements. An automatically backlit display shows all gas con-
centrations being measured. LEDs located on the front of the
instrument indicate preset visual warnings of increased gas
concentration. All gases are continuously sampled with the use
of an internal pump. Audible and visual alarms warn the operator
of hazardous conditions being sensed. The preset alarms are
indicated by a red flashing LED, display indicator and alarm

sound. The combustible gas alarm is preset from 50% LEL (2.5%
methane or 1.1% propane) to 17% methane (12% propane). The
carbon monoxide (CO) alarm is factory preset at 35ppm. The
oxygen (O2) alarms are preset at below 19.5% and above 22.5%.
The hydrogen sulfide (H2S) alarm is preset at 10ppm.
The Sensit®Gold instrument is approved by Underwriters Labo-
ratories to UL913, for Class
I , Division 1, Groups C & D hazard-
ous locations when used with approved batteries.
APPROVED BATTERIES: Duracell MN 1400BK or equiva-
lent alkalines. Panasonic HHR300CH or equivalent NiMH
(Nickel Metal Hydrides).
