Specification
• Pressure: 3 to 65 psig (122 to 549
kPa abs). A check valve in the inlet
prevents the sensor flow cells from
going dry if sample flow is lost. The
check valve opens at 3 psig (122 kPa
abs). If the check valve is removed,
minimum pressure is 1 psig (108 kPa
abs).
• Temperature: 32 to 122 °F (0 to 50
°C)
• Minimum flow: 3 gal/hr (11 L/hr)
• Maximum flow: 80 gal/hr (303 L/hr);
high flow causes the overflow tube
to back up.
