INFRARED (NDIR) PORTABLE Hydrogen Sulfide(H2S)GAS DETECTOR Wuhan Cubic Optoelectronics Co.Ltd Add:Fenghuang No.3 Road, Fenghuang Industrial Park,Eastlake Hi-tech Development Zone,Wuhan 430205, China Tel: 86-27-81628831 Fax: 86-27-87405251 www. GasSensor.com.cn

0.13‐4.6ppm have smell of rotten eggs, usually does not harm to human body Have stimulation feeling at the beginning, but will disappear soon. Threshold Limit Value for most countries. Over this concentration, people must wear gas masks. Limited to contact directly for 10 minutes. Stimulate on throat, slight headache, more than 4 hours exposure can lead to death. Will immediately destroy olfactory system; longer exposure will cause throat ambustion and even death.. Will cause quickly lose consciousness, >500ppm respiratory arrest and death

•This instrument integrated leading electrochemical technology from Europe and have advantages of long lifetime (up to three years), good stability, strong anti‐interference ability, wide range, etc. •This device adopted large‐scale digital integrated circuits and ultramicro consumption components in circuit design, so that it has features of very small size, light weight, easy to carry, and has functions of digital display,sound & light alarm

Applications Portable H2S detector is an ideal instrument with alarm function to detect the concentration of H2S in many industries, such as: • Petrochemical • Rubber, • Fertilizer, • Leathe • Wastewater treatment • Pulp and paper • Electric utilities • Food and beverage

How to work? Measurement In the environment Alarming functions Alarm is able to set the alarm at any point, alarm value and set value displays the difference should not exceed ± 0.05% (the full range 0‐10%) Alarm sound level intensity at a distance of not less than 75dB (A) in the distance of 1m. Optical signal visibility in the dark should not be less than 20m away
