HTPB Series
HTPB series is a family of humidity probes that offers a variety of measurement
parameters with precision accuracy: RH, temperature, dew point, pressure (psia),
ppmv, ppmw, gr/lbs, etc. The probe is easily adaptable for most applications
including high temperature and high pressure conditions.
HT75 - Humidity/ temperature stainless steel probe with a stainless steel sinter
lter, RS232 and 3 0-10Vdc outputs, RH measurement range is 5 to 95%RH with an
accuracy of +/-1%, operating temperature range -20C to 75C, dew point range 30
to -60C, default outputs: RH, temperature and dew point.
HTB75 - Humidity/ temperature/ barometric pressure stainless steel probe
with a stainless steel sinter lter, RS232 and 3 0-10Vdc outputs, RH measurement
range is 5 to 95%RH with an accuracy of +/-1%, pressure range is (barometric
pressure) 300-1100mb, operating temperature range -20C to 75C, default outputs:
RH, temperature and pressure.
HTP55 - Humidity/ temperature/ high pressure stainless steel probe with a
stainless steel sinter lter, RS232 and 3 0-10Vdc outputs, RH measurement range is
