Tender Details

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 by catalytic oxidation. The following measuring range must be coveredbe: 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 via an rs-232 interfacewith bayern-hessen protocol for data transmission and control. the measuring device must have an ethernet connection. remote access using remote desktop or team viewer should be guaranteed. the measuring device must be designed for a power supply of 230 v, 50/60 hz. themeasurement 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 by the uv lamp to correct intensity fluctuationshave a reference detector. the measuring device must be equipped with an internal permeability device for automatic functional controls. the following requirements are set to this facility: the permeability device must be heated and the temperature must be regulated stable at +/- 0.1 cbecome. the temperature of the permeability device should be in the area of ​​40-50 c. the permeability device is permanently rinsing with zero gas in order to prevent enrichments of h2s in the system to prevent the zero -point test, dilution and null gas required for dilution and rinsing must be from the measuring device,, for example, by using external gas cleaning cartridges. external zero gas supply is not available in the measuring stations. the internally generated zero and...
