The HX15 Series 2-wire remote
transmitters measure relative
humidity and temperature over
a large temperature range

-40 to 180°C (-40 to 356ºF).
The HX15-W 79 mm (3")
stainless steel probe is used
for wall mounting. The HX15-D
229 mm (9") stainless steel duct
probe has a removable flange.
The probes are connected to
housings with 1 m (40") PFA
cables. Probes are not field
replaceable.
