Details: item description 1. a standard gas sensing chamber having sensor sample stage of 2" dia (temp: rt to 400c), 4 micromanipulators with tungsten tips. ports on chamber for pumping, vacuum gauge humidity sensor, port of 6cm view on top gas inlet/outlet, septum for voc sensing. chamber mounted on a convenient frame2. humidity sensor with display (no interfacing/ only read),3. fully automated ppm level dual dilution chambers with 2 numbers of mfc (1000 sccm standard mfc for dilution gas and 100 sccm corrosive mfc for sensing gas) with 4 gas manifold for connecting various gases. appropriate solenoid valves for directing gas to appropriate component. the gas sensing system must be capable of performing both static gas sensing as well as dynamic gas sensing and should be used for testing as well as calibration of wide range of gas sensors (physisorption, chemisorption and others sensors) within system specification range.4. rotary pump with pirani gauge (tpr270 from pfeiffer vacuum) with me
