0.05,0.5,1.0,5.0, or 10. Installation Style: For sensors with a 0.05 cell constant, use K-inch or %-inch male NPT compression fittings made of Kynar (PVDF) or 316 stainless steel. For sensors with any other cell constant, use a %-inch male NPT compression fitting made of Kynar or 316 stainless steel.
