Currently the SWRCB UST program staff discourages the use t <br /> strip discriminating sensors at new installations in California. This is due to concerns about the imp <br /> repeated/prolonged exposure to hydrocarbons may have on the sensor's ability to alarm and recow <br /> alarm reliably. Since current evaluation protocols do not address this issue,no new polymer strip sl <br /> should be installed until new evaluation protocols are in place. <br /> poi mer strip float switch <br /> Discriminating Spenser Di Pan nleadedaausoline diesel water <br /> Sensor 794380-322 <br /> Response time(sec) - rs <I <1- high* low' <br /> 10 min 2-12 h <br /> Recovery time(sec) N/A"Lower detection limit- height(in) N/DMS N/A <1 <1 <br /> Lower detection limit-Thickness (in) N/D 7.66 1.37 <br /> 0.005 <br /> Discriminating Containment Sump 0.005 N/A N/A <br /> Sensor 794380-352 - <br /> Response time(sec) ^ 10 min 2-12 hrs <1 <br /> Recovery time(sec) N/A <1 <br /> Lower detection limit- height(in) N D N/A <1 <1 <br /> N/D 12.28 1,35 <br /> Lower detection limit-thickness (In) 0,005 ON/A <br /> N/A N/A <br /> h"p://www.swrcb.ca.gov/cwphorne/ust/leak_prevention/1g113/Vendor_Files/veeder_root_O.h.._ 6/13/05 <br />
