Spark CO / Spark+ CO
Trace-level carbon monoxide detection
Measure CO with Confidence
Whether for process control or quality control, gas suppliers need accurate, low-level contaminant monitoring to ensure gas quality with no impurities. For refineries and chemical plants it is especially critical to measure carbon monoxide in hydrogen since high levels can poison a customer’s process and a supplier’s reputation.
Monitor purity with the Spark CO analyzer, designed to provide unparalleled accuracy and reliability for your most critical carbon monoxide measurements. Compact and easy to use, this analyzer features Tiger Optics’ proven Cavity Ring-Down Spectroscopy to detect as low as 200 ppb of carbon monoxide in your process streams.
Users enjoy freedom from periodic sensor maintenance, and with no calibration gases required, operating costs are nearly eliminated. With drift-free stability and rapid response time, the Spark CO is ideal for the continuous, online gas monitoring that is critical to process control in gas and chemical industries or anywhere purity is a necessity. Choose the Spark+ CO when lower detection limit is required.
The Spark CO ensures purity and process protection with:
- Parts per billion (ppb) carbon monoxide detection capability
- Wide measurement range, from 0–2500 ppm (in hydrogen)
- Freedom from calibration (absolute measurement technology)
- Low cost of ownership
- Easy to use touchscreen and remote software interface
- Spark+ version with 40% lower LDL available
