Portable Dew Point Monitor
HTM, a Series of Portable Dew Point Monitors
The HTM Series is a series of portable, battery powered dew point monitors that
provide a quick response for dew points to –60°C. The unit is factory set to display
humidity, temperature and dew point. Other selectable parameters are accessible
via the RS232 connections. The sensor probe has a wide temperature range and is
resistant to most chemicals. For applications where drawing a sample is not feasible,
the Model HTM sensor is flexible enough to be removed from its sample chamber and
be remotely mounted. Field replaceable sensors are available with an interchangeability
of ±1%. The HTM is ideally suited for compressed air and dryer applications. The
HTM dew point monitor is calibrated and adjusted to a traceable reference standard
and comes with a NIST traceable calibration certificate.
