Single pass sample cell for highest measurement ranges and sample cell heating up to 180 °C for process gas measurements. Typical uses include process measurements where concentrations are in the high % levels and shortest response times are needed.
The GASMET Cr-1000 is designed for speed and reliability.The single pass sample cell provides high optical throughput
and very quick response times. As the sample cell is available for short path lengths only, it is optimal for percentage
concentrations. Typically Cr-1000 is used for process measurements and catalyst research applications. The rugged
stainless steel sample cell is typically heated up to 180 ºC.
Higher temperatures available by special request.
Storage temperature: -20 - 60°C, non condensing
Power supply: 100-115 or 230 V / 50 -60 Hz
