Accurate detection of trace levels of moisture has been a challenge to the process world owing to the fact that high concentrations of water are present in the atmosphere; approximately 1% by volume in room air. Teledyne Analytical Instruments is well aware of this challenge, having successfully developed one of the broadest lines of trace ppb/ppm O2 analyzers commercially available. In developing our trace O2 line, we have had to contend with the fact that 209,000 ppm of O2 is present in the atmosphere - ready to jeopardize the analysis of typically less than 1 ppm of O2. Teledyne is...

HTF™ vs. Conventional AI203 Sensor Change of Capacitance with Dewpoint HTF™ vs. Conventional AI203 Sensor Comparison of curve shape 200 Conventional Sensor 60x amplified The change of capacitance with moisture of HTF sensors over the full measurement range is 60 times larger than that of conventional sensors. However, because of the improved linearity of HTF sensors at the low end, capacitance changes with moisture are about 600 times larger than that of conventional sensors. The larger sensitivity makes HTF sensors more stable and resistive to other influences such as temperature,...

MOUNTING HOLE PATTERN SET % X10-3 HILO PPM TEMP ϒ F Cϒ DEWPOINT PSI G/M3 LGS MOUNTING HOLE PATTERN Operating Principle – Model 8800P Aluminum oxide sensors absorb water molecules much faster than desorb. It is therefore an advantage if, at the beginning of a measurement, the sensor is dryer than the sample to be measured. 1/2" NPT HUB (HIGH VOLTAGE APPLICATION) The 8800P accomplishes this by keeping the sensor in dry storage until the measurement is taken. The sensor slides directly from dry storage into the sample cell without coming in contact with ambient air. After the measurement is...
