REOTEMP is proud to introduce a revolutionary product for the compost industry. The Fast Response Windrow Thermometer has all of the assets the Heavy-Duty Thermometer has, however it is stronger and quicker. The extra sensitive tip gives an accurate temperature reading twice as fast as the Heavy-Duty Probe. The stem is now reinforced with 3/8" stainless steel, providing you with a more durable instrument so that you do not need to replace them as often. The bottom line is that this instrument will save you time and money. You 'll be walking the windrows in half the time!
