Heat treated ABS plastic plus extra durable buttons means that the Escali Waterproof Digital Thermometer is built to last. The extra thin 1.2 mm probe tip allows for ultra fast measurements within 1-3 seconds. IP68 protection will protect against immersion in water and the intrusion of dust. Take measurements at any angle, even when the display is not visible using the temperature hold feature. Capture minimum and maximum temperatures with directly watching measurements. Snap the protective probe sheath onto the end of the thermometer to extend the reach. Measures temperatures from -40°F to 450°F (-40°C to 250°C).
