Product Description

USB-PTH420-CAL: Enhanced precision USB Atmospheric pressure, temperature and relative humidity sensor – calibratable.

Part of the PTH series of sensors, the PTH420 is specifically designed to acquire environmental temperature, humidity, and atmospheric pressure (barometric) data where enhanced precision (±0.1°C/±1.5% RH) is required. With its factory calibrated, linearized and temperature compensated digital sensor chip, it is field interchangeable. Thanks to its precision electronics, tiny variations in atmospheric pressure, temperature, and humidity can be acquired using a standard USB port.
The compact probe eases integration, even in space-constrained locations, and the built-in particle filter protects against dust, soot, and other contaminants.
