A new level of speed, convenience, accuracy, and low maintenance in a BOD Probe. The built-in stirrer disassembles easily for cleaning and provides vigorous sample agitation, preventing oxygen stratification. The free-standing probe stand can be used for storage and also functions as an air calibration beaker. One-Touch control provides fast, easy BOD analysis with the new Thermo Scientific® Orion Star™ Series meters. Just press "Measure" on the meter to initiate stirring. When stability is achieved, stirring stops automatically, and the reading is taken.
