Ideal for environmental atmospheric pressure, temperature, and relative humidity acquisition, this sensor features a 2-layer filter that protects against harsh conditions. Moreover, this calibratable ±0.54°F (±0.3°C) accuracy sensor works with the instrument in virtual COM port mode, and the USB port makes it usable in minutes.

A member of the PTH series, the PTH200 is a USB sensor designed for environmental data acquisition, offering an operating temperature range of -40 to 158°F (-40 to 70°C) with a typical accuracy of ±0.36 to ±0.54°F (±0.2 to ±0.3°C) and a fine resolution of 0.018°F (0.01°C). It also measures relative humidity from 0 to 100 %RH with an accuracy of ±2 %RH and a resolution of 0.01 %RH. For atmospheric pressure, it covers a range of 45 to 110 kPa with an accuracy of ±0.15 kPa at 77°F (25°C) and a resolution of 0.0065 kPa. Thanks to its factory-calibrated and temperature-compensated digital sensors, the PTH200 detects very small variations. Its robust design with PET mesh and PTFE membrane filters provides effective particle protection, and its 1-meter USB cable allows easy integration. It operates within conditions of -40 to 158°F (0 to 70°C) for the USB cable interface and requires protection from direct exposure to water or snow.
Like all Dracal measurement instruments, the PTH200 is compatible with free software tools, making it an essential component of a DAQ solution. For those who wish to integrate the PTH200 into their system, there are two options available: command line tools and VCP mode. If you prefer a graphical interface, DracalView is the appropriate choice.
