UltraRAE3000
The UltraRAE 3000 is the most advanced Compound-Specific Monitor on the market. Its Photoionization Detector’s (PID) extended range of 0.05 to 10,000 ppm in VOC mode and 50 ppb to 200 ppm in benzene-specific mode makes it an ideal instrument for applications from entry pre-screening during refinery and plant maintenance to hazardous material response, marine spill response and refinery down-stream monitoring.
