Bộ chuyển đổi nhiệt độ Vaisala HMT334

Model: HMT334

Hãng sản xuất: Vaisala

Thông số kỹ thuật:

The HMT334 incorporates Vaisala’s more than 30 years of experience in industrial humidity measurement. The sensor provides accurate and reliable measurement and is immune to particulate contamination and most chemicals.
Graphical display of measurement trends and real time history
The HMT330 series features a numerical and graphical display. The user can easily monitor operational data, measurement trends and up to one-year history.
The optional data logger with realtime clock makes it possible to generate more than four years of measured history, and zoom in on any desired time or time frame.
Using a serial line, the measurement data can be transferred to a PC where it can be further processed and copied to other programs.

For pressures up to 100 bar and vacuum applications
For temperatures -70 ... +180 °C (-94 ... +356 °F)
ISO and NPT threads available
Application example: test chambers
