Add to compare

The III SP Gas Analyzer is an advanced optical-based Tunable Diode Laser Absorption Spectrometer (TDLAS) designed for operation in certified hazardous areas and compatible with SIL2 installations. It features a transmitter and receiver unit that mount diametrically across the stack, duct, pipe, or reactor vessel, eliminating the need for high maintenance sample conditioning systems. The analyzer provides near-instantaneous on-line analysis with no cross interference to background gases. It is zone 1 Exd certified, suitable for use in SIL2 systems, has a compact footprint, automatic continuous system health check, low power requirements (<15 watts), factory calibration with no zero drift, and no interference from other background gases. It is ideal for applications such as process safety, inertization control, FCC units, coke oven gas, combustion control, selective catalytic reduction (SCR), selective non-catalytic reduction (SNCR), DeNOx, and emission monitoring. The product offers reliable and proven non-contact optical laser measurement, high measurement reliability, low ongoing cost of ownership, and very low maintenance. It is certified for use in hazardous areas with ATEX and CSA ratings, and it supports various gas detection limits and ranges, including O2, CO, CH4, H2O, NH3, and CO2.
