USB ATMOSPHERIC PRESSURE, ENHANCED PRECISION TEMPERATURE AND RELATIVE HUMIDITY SENSOR The PTH420 includes an enhanced precision temperature and humidity sensor, pushing the precision limit a step further. It is designed for environmental temperature, humidity and atmospheric pressure (barometric) data acquisition. Its core digital sensor chips are built around industry-proven technologies and are individually factory-calibrated, linearized and temperature-compensated, resulting in a cutting-edge performance. The compact probe eases integration, even in space-constrained locations, and the built-in particle filter provides protection against dust, soot and other contaminants.
