Combined Pressure, Humidity and Temperature Transmitter PTU300

Huomaa, että PTU300-sarjan valmistus lopetetaan pian. Sarjan tuotteet korvataan Indigo-sarjan tuotteilla. Älä määritä PTU300:tä uusiin projekteihin, vaan tutustu Indigo-lähettimiin ja ‑mittapäihin, jotka nekin on suunniteltu haastaviin sovelluksiin.

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. For demanding meteorology applications, view this page.
