Argon Purity Analyzer

The Argon Purity Analyzer typically measures argon gas purity in the range of 0 to 100%, with impurity detection thresholds down to 1 ppm depending on the sensor type. It uses technologies such as thermal conductivity detectors (TCD), electrochemical sensors, or zirconia-based oxygen sensors for precise measurement. The device operates at an input gas pressure range of 1 to 10 bar and a flow rate between 0.2 and 2 L/min. Accuracy is usually within ±1% of full scale, with repeatability better than ±0.5%. Response time (T90) is less than 10 seconds. Operating voltage is 220V AC or 24V DC, and the ambient operating temperature range is 0°C to 45°C. The unit includes a digital LCD/LED display, RS232 or USB output for data logging, and calibration options for standard reference gases. Housing is typically made of aluminum or stainless steel, and the analyzer can be configured for portable, panel-mounted, or rack-mounted installations. Maintenance is minimal, and the device is factory calibrated with options for annual recalibration.
