• Complete hazardous area installation
• Single- or dual-channel measurement
• Moisture content, dew point and pressure
• Calibration traceable to NPL (UK) and NIST (USA)
• Remote global access options
• Sour gas compatible
• Field calibration maintenance
• Range -120 to +30°Cdp, 0.001 to 30,000 ppm_V
