Use the thermometer to determine daily temperature fluctuations in microhabitats such as burrows or rocky crevices. The cable length is 3 meters (10 feet). The probe can be used in freshwater, brackish, or saltwater conditions and is accurate to within 0.5° C (1° F). The thermometer features an easy to read, lighted display.
