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.

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,
