This Dickson HT200 Waterproof Temperature Data Logger with Software is in great condition and was removed from a working environment. This unit came from a local lab that had surplus lightly used equipment. The data logger is most likely in unused condition but was listed as used due to lack of factory packaging. We guarantee this unit to be in functional condition with a 30 day full money back return policy. We urge customers to view all photos as they show overall condition, included accessories and useful information. Please feel free to contact us with any questions.
