The PTU300 is a unique instrument measuring three parameters simultaneously: barometric pressure, humidity, and temperature. The instrument has four different humidity probe options for various measurement needs. Reliable HUMICAP® and BAROCAP® sensor technologies make it suitable for several applications such as engine testing booths, calibration laboratories, and marine engine air intake monitoring.
