Hampshire Controls' Temp-Check thermometer measures the temperature of plasma, red blood cells, cryoprecipitate, and other blood components, and makes determining the temperature of blood components easier, faster, and non-invasive for lab technicians. Users simply place bags on the insulated pad and receive an accurate temperature reading within 10 seconds. The lightweight unit includes a rechargeable battery back up for easy portability when an outlet is not available. The Temp-Check thermometer will run for 12 hours when fully charged. All products are made in the USA.
