10.4 Concentration guarantee term of standard gas cylinder (for NOx, SO2, CO and O2 analyzer)

Kind of gas

Concentration range

Guarantee term

 

 

 

NO/N2

0.4ppm or more, and less than 250ppm

6 months

 

 

 

NO/N2

250ppm or more, and less than 5%

1 year

 

 

 

SO2/N2

0.4ppm or more, and less than 250ppm

6 months

 

 

 

SO2/N2

250ppm or more, and less than 1 %

1 year

 

 

 

CO/N2

2.4ppm or more, and less than 100ppm

6 months

 

 

 

CO/N2

100ppm or more, and less than 15%

1 year

 

 

 

O2/N2

0.9% or more, and less than 25%

1 year

 

 

 

N2

*None

 

 

 

Air

*None

 

 

 

* Schedule the use for about one year under proper control.

Note: It is empirically known that standard gas concentration remains within the adequate accuracy for 6 months or 1 year. However, gas maker’s guarantee term is as listed in the above table. Therefore, replacement is required within the guarantee term when importance need be placed on traceability.

10.5 Maintenance of sampling device

(1)Replacement of filter element of gas extractor (extractor type : ZBAK1)

(a)Turn off power supply to the extractor

(b)Turn off the pump of gas analyzer

(c)After making sure the temperature of extractor has dropped adequately, detach the rainproof cover (remove the wing bolt on the flange side).

(d)Remove the locking wing bolt and pull out the internal parts while gripping the handle for filter ex- change.

Although you may feel slight stiffness in pulling out the handle for filter exchange, it should be pulled out gradually while turning it.

(e)Remove the metallic mesh filter from the seal fixture.

(f)After mounting a new element, reverse the above procedure.
