USB ATMOSPHERIC PRESSURE, ENHANCED PRECISION HUMIDITY AND WIDE RANGE TEMPERATURE SENSOR The PTH450 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 and field interchangeability. Thanks to its probe special construction, the PTH450 can sustain a wide range of temperature. The compact probe eases integration, even in space-constrained locations, and the built-in particle filter provides protection against dust, soot and other contaminants.

AVAILABLE CHANNEL(S) SPECIFICATIONS Parameter Miscellaneous ADC resolution Long-term stability Temperature compensated Lifetime As displayed in our logging software bits – – years Each sensor is individually conditioned by the manufacturer of the semi-conductor sensor chips, in the best stable conditions and their correction coefficients are recorded in each of them. If water condensation or splashing is possible, it is recommended to install the probe pointing down to reduce the risk of water build-up in the sensor. If water splashing is possible, protect the sensor and the cable converter using...
