The Sentinel 6T refrigerated sewage sampler provides the ultimate in sampling accuracy and long term system reliability for your wastewater sampling program. The Sentinel 6T is a flow-through, fixed dipper automatic sampler. A 2 inch inlet, 3 inch exhaust line and open dipper assure a clog resistant system suitable for use with all types of wastewater. The Sentinel 6T’s efficient thermoelectric refrigeration system preserves a 2 gallon composite at 4-10ºC and eliminates problems with Freon® or other pressurized gas.
How it Works:
Sewage or process wastewater flows into the integral sampling chamber through a 2” NPT inlet line at the rate of ten to thirty gallons per minute by either gravity or external pump. Representative samples are assured by thorough mixing of the liquid before it flows over an adjustable weir to waste through a 3” NPT exhaust line.
A sampling dipper attached to an oscillating shaft is located in the sampling chamber. Responding to flowmeter signals or actuated by the sampler’s adjustable timer, the dipper collects a precisely repeatable 25 ml sample from the flow in the sampling chamber. The dipper then returns to the raised position, and deposits the sample in the composite container in the sample storage compartment. The sample is stored in a thermostatically controlled refrigeration compartment until removed by the operator. A non-contact switch turns the system off when the composite is complete.
