The THX-400-GP probe used with an HDX handle
is ideal for general purpose immersion measurement
in gases and liquids. Made from a rugged 3.0 mm
(1⁄8 ") O.D. 304 stainless steel sheath 3 m (10') long,
the probe will adapt to most process applications.
A high precision 44033 thermistor element is used
(2252 Ω @ 25°C/75°F), which provides 0.1°C/F
interchangeability and a temperature range of -40
to 100°C (-40 to 212°F).

The THX-400-AP is designed for HVAC
applications. The small diameter sheath and
radiant energy shield easily fit into duct work, grilles
and vents. The probe will work with the OMEGA
HDX handle or can be permanently mounted using
OMEGALOK®compression fittings. Made from a
rugged 4.8 mm (3⁄16 ") O.D. 304 stainless steel
sheath 3 m (10') long, the tip is perforated to
expose the thermistor bead to air flow for fast,
accurate measurements. The 44033 precision
thermistor element is rated up to 100°C (212°F).

The THX-400-NP probe used with an HDX handle
will easily pierce soft and semi-frozen material as
well as soil and sand. Made from a rugged 3.1 mm
(1⁄8") O.D. 304 stainless steel sheath 3 m (10') long.
A high precision 44033 thermistor element is used
which provides 0.1°C/F interchangeability and a
temperature range of -40 to 100°C (-40 to 212°F).
