The REOTEMP OxyTemp combines a percent oxygen probe and a temperature probe into one unit. Our patent pending, easy clean-out feature allows you to clean out a clogged tip with one simple adjustment. The OxyTemp draws a sample of air from deep within a compost pile, blows the sample across the oxygen sensor and displays the percentage of oxygen in a matter of seconds. The probe measures the temperature with this same sample and displays it next to the oxygen. 9v battery included. 2′, 3′, 4′, 5′ or 6′ stem length.
