Attention:

1. All operators who operate and test our company’s factory instrument must

read this manual carefully before operation. Only the instrument of this company

is operated according to the operation manual of this company, can the instrument

work normally.

2. The usage of the instrument of this company must conform to the

regulations confirmed by the operation manual. The maintenance of the

instrument and changing of the parts must adopt accessories offered by this

company, and the maintenance operators must be the works who have been

trained.

3. If the user repairs this product or change accessories arbitrarily and does

not conform to the above-mentioned manual, the operator shall be responsible for

the reliability of the instrument. And this company is not responsible for the

warranty.

4、The instrument should be calibrated every half year; the flame-proof piece

of the instrument sensor or the waterproof and breathable memebrane should be

cleared or changed periodically, or the detection sensitivity would be affect

because the dust and impurities would block the protective hole.

5. The usage of this instrument also should conform to the laws and

regulations of the domestic relevant departments and instrument management of

the factory.

6. Determined by the characters of the sensor, the instrument should be

calibrated every three months (the company can offer the standard gas).

7. The sensor is the sensitive part, so if the measuring environment is full of

lamp black, moisture, and dust, the filtering pretreatment is necessary, or the

sensor is easy to be damaged.

8. The instrument adopted the electrochemical sensor must not be exposed in

the high concentration gas (except the oxygen), or poisoning and decreasing

service life of the sensor is easy to happen.

9 、 When pipeline instrument makes the operation of calibration and gas

detection, the flow shall be controlled within 160-200ml/min, or the value would

be unsteady or inaccurate.

I. Application and fundamental principles:

Firstly, thanks you for choosing OC-905 series portable gas detector .

OC-905 portable gas detector is a high-end detector, which adopts the full

metal shell. OC-905 adopts the brand new imported sensor and 32-bit low power

processor; the circuit adopts four wiring, which has a good effect on

anti-interference and week signals; the independent high precision imported AD

chip, and with the signal processing algorithm owned by our company make the

accuracy of the measuring result higher and steadier; 2.5 inch lattice display

interface makes the numerical reading more intuitional; the top-ranking process

design makes the quality of OC-905 monolithic. The performance of this

instrument is steady and reliable, which is the advanced level in this industry.

The product is widely used in: the place where need to detect flammable and

combustible, poisonous and harmful gas continuously, such as, petroleum and

petrochemical industry, metallurgy, chemical industry, scorching, municipal

administration, biopharmaceutical, environmental protection, laboratory of school,

automobile exhaust, electric power, shipping, and sewage treatment and so on.

1.1 Safe instruction



The too high or too low of the content of the oxygen can affect the

reading of the flammable gas sensor.



The sudden change of atmospheric pressure may affect the reading of

the oxygen sensor.

 The steam of the silicone compound would catalyze the burn type

sensor and cause damage, please make sure that there are no this kind of materials

in the application environment.

 In the process of using, please keep cleaning the sensor air inlet. The

bulkhead of the air inlet would make the reading of detector low.



Please do not to disassemble this instrument voluntarily in order to

guarantee that the using of the detector is safe and reliable.



Please do not put this detector in the high temperature, moist or strong

static environment.

 Please do not clean this machine using any corrosive liquid.



The user cannot change the parts of this product voluntarily, and should

deal with the breakdown in the process of operation with the maker, which can

completely eradicate damage phenomena.



The installment, use and maintenance should conform to operation

manual, GB3836.13-1997 “explosive air environmental electrical equipments the

thirteen part: the maintenance of the explosive air environmental electrical

equipments”, GB3836.15-2000 “explosive air environmental electrical

equipments the fifteen part: the electrical installment in the dangerous place

- 5 -

(except coal mine)”, GB3836.16-2006 “explosive air environmental electrical

equipments the sixteen part: the check and maintenance of the electric installation

(except coal mine)” and GB50257:1996 “the relevant regulations of “the

explosion of the installation works of electrical equipments and the construction

of electrical installation in the fire dangerous environment”.
