Hydrogen sulphide - Import export

Sulfuric Acid 98% (H2S04) known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H2SO4 It is a colorless, odorless, and viscous liquid that is miscible with water Pure sulfuric acid does not occur naturally due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, it is an oxidant with powerful dehydrating properties Industries: Household chemicals, Fertilizers, Adhesives, oils, greases, Horticulture, Batteries Properties: CAS number 7664-93-9 WE number 231-639-5 Chemical formula H2SO4 Molar mass 98,08 g/mol Customs tariff code 28070000 ADR UN 1830, 8, II pH 0,3 (49 g H2S04/1000 ml H2O @25°C) Melting / freezing point +1,8°C (98.5 %), -12.6°C (96 %), -27°C (93 %) Boiling point range + 275°C ± 5°C (100%) Relative density 1,8144-1,8305 kg/l (90-100%)

Scott Protégé ZM is maintenance-free, user-friendly and a reliable gas measurement device. Once the Protégé is activated neither further charging nor calibration is necessary! During the run time of 2 years the device measures oxygen, carbon monoxide or hydrogen sulphide. Maintenance-free Oxygen, carbon monoxide, or hydrogen sulphide In order to extend battery operation time, after measurements power save modus turns on Triple- warning device with optical, acoustic and vibration alarm signals LC-display can be customized and it indicates remaining device runtime, gas measured values in real-time or both Alarm thresholds as well as deadlines for inspection and calibration are configured by the user itself Function for data recording Complies with protection class IP66/67 (certified by an independent institute) Optional expandable by testing facility with 4 equipment pockets and programming device for IR- interface Data sheet

Xgard of the manufacturer Crowcon is a fixed point gas detector for flammable and toxic gases as well as oxygen. Dangers presented by toxic and flammable gases as well as oxygen levels are unique to each installation. Xgard provides four different versions so you can choose exactly what you need in order to fulfil requirements depending on your site. Xgard Type 1: Intrinsically safe detector for toxic gases and oxygen Xgard Type 2: Ex- proof detector for toxic gases and oxygen Xgard Type 3: Ex- proof detector for flammable gases Xgard Type 4: Ex- proof detector for flammable gases at high temperatures Xgard Type 5: Ex- proof detector for flammable gases with 4-20 mA- output Xgard Type 6: Ex- proof detector on basis thermally conductive Xgard Type 7: Ex- proof hydrogen sulphide detector Xsafe: Detector for flammable gases in safe areas Advantage of Xgard-Detector Engineered for ease of maintenance, running costs are kept to a minimum Simple exchange of sensors by connection...

Protégé is an exceptionally multi-gas detector in shape of an hourglass, which fits in the palm of the hands. It is construed to control potential dangerous concentration of combustible gases, carbon monoxide and hydrogen sulphide, decrease of oxygen or –enrichment. Activation of functions is done intuitively, so it enables the user to concentrate completely on the task. Moreover, Protégé is equipped with automatically maintenance-functions, which contributes to a considerable reduction of costs for maintenance and training. This multi-gas device is provided with an own software allowing individual and specific adjustments and data recording. Features of Protégé: Easy handling with calibration and operation self-test Complies with all requirements of global supervisory authority through robust construction Easily maintained is due to automatic zero- and span calibration and easy replacement of sensors Through special ergonomic shape of an hourglass, well suited for all hand...
