- Description:
- There are three measuring devices for hydrogen sulfide in the ambient air.
The measuring device must meet the following requirements:
measurement of H2S in the ambient air according to the method of UV fluorescence by means of conversion into SO2 through catalytic oxidation.
The following measuring range mustbe covered: 0-1000 ppb
The detection limit (3σ) should be approx. 2 ppb.
The deviation from the linear regression function must be ≤ +/- 2 % of the measured value.
The setting time for reaching 90% of the target concentration (approx. 630 ppb H2S) must be 200 seconds.
The measuring device must be overan RS-232 interface with Bayern-Hessen protocol for data transmission and control.
The measuring device must have an Ethernet connection.
Fern access using remote desktop or team viewer should be guaranteed.
The measuring device must be for a power supply of 230 V,50/60 Hz.
The measuring device must have a hydrocarbon scrubber for the measuring gas.
The measuring gas pump must be integrated in the device. Measurement devices with an external pump are unsuitable due to the space conditions in some measuring stations.
The device should be corrected byIntensity fluctuations of the UV lamp have a reference detector.
The measuring device must be equipped with an internal permeability device for automatic functional controls. The following requirements are made to this facility:
The permeability device must be heated andThe temperature must be regulated stable to +/- 0.1 C.
The temperature of the permeable device should be in the range 40-50 C.
The permeation device is permanently rinsed with null gas to prevent enrichments of H2S in the system
for the zero point test, for dilutionAnd nullgas needed for rinsing must be generated by the measuring device, e.g. by using externa... - Documents:
