Safety and Maintenance Safety Precautions The sensors cannot be used for gas metrology of fluoride or fluoride-containing gases. For updates on the product certification information, please contact the manufacturer. Use for other gases such as extreme corrosive and toxic may cause the product malfunctioning or even severe damages The product sealing is ensured to work under a working pressure of 8 bar and is leakage proof tested before the shipment. However, cautions and further leakage tests are important at installation since any leakage could cause severe safety issues. The power supply...
