How often
should I calibrate my H2S gas sensors?
We recommend that all H2S gas detectors
be calibrated at least once every 90 days to ensure
integrity. We are not implying that the sensor will
drift or have problems within this period but frequent
calibration checks merely ensure the integrity and
operation of the life protecting equipment.
This should be used as a guideline only and in some
applications more frequent calibrations may be required.
Each application must be carefully evaluated to
determine the frequency of calibration. What is the
recommended installation procedure for an H2S sensor?
The sensor should be located 12 to 36 inches from
the floor wherever H2S gas may be
present. Why do we
recommend mounting the sensor low?
H2S gas is heaver than air, thus
it will settle. How do you
calibrate an S4000TH H2S detector?
You can use ampoules and a breaker bottle (P/N 50000) or a calibration
kit (P/N 1400250-x) consisting of a bottle of H2S
gas, a .2 Liter / min regulator, 4 feet of tubing
and a calibration cup. Why would
I use a calibration kit over ampoules?
The calibration kit allows for flowing H2S
gas. This eliminates calibration errors from high
humidity or from contaminants which absorb H2S.
Flowing H2S is less likely to be
absorbed by the moisture/contaminants. When is a
splashguard recommended?
All the time for outside installations and even
inside installations where wash downs occur. Should I calibrate with the splashguard on the sensor? Yes, if the sensor has a splashguard on it, it should be calibrated with the splashguard in place. I have a 2280A controller that I'm currently using only 3 channels. Is there a way I can have the fourth channel not show as being in fault?
Yes, you can use our sensor simulator (p/n 50460-3) for any unused channel(s) on any of our hydrogen sulfide (H2S) controllers. What accessories do you offer for your MOS sensors?
There are a variety of accessories for our MOS sensors such as a splash guard (P/N 10395-1), dust guard (P/N 10110-1), sintered stainless steel dust guard (P/N 1800822), and duct mounting plate (10041) to name a few.
