Portable gas detector ISC Ventis LS, H2S/O2/LEL/CO/SO2/NO2




Gas Detector Ventis LS Industrial Scientific

– Detects one to four gases including H2S, O2, LEL, CO, SO2 and NO2
– Transmits gas level and alarm information over a Wi-Fi network
– Sends an alert to the control room if the worker activates the instrument’s panic button or if lack of motion is detected
– Enables a worker’s location to be pinpointed in real time at a central console
– Operates on iNet – Industrial Scientific’s unique Gas Detection as a Service solution
