The gas supervision instruments can detect CO, H2S, VOCs and O2 at a precision of parts per million (ppm), an example being carbon monoxide which ranges from CO: 0-1000ppm, accuracy: ±5%). Multi gas monitors with pump sampling (flow rate: 0.5L/min) offer primary setpoints for sound, light and vibrational signals, in addition to data logging features for 500 hours, with real time alerts for visual, audible and vibrational alerts (alarms). These instruments are very important in confined spaces in a chemical plant, helping fulfill OSHA PEL and NIOSH REL standards while having explosion proof features (ATEX/IECEx certified)rated for Zone 0/1 areas.
