General Description
Overview The portable trace moisture analyzer Model DPT-600 Plus is a rechargeable battery operated, designed for applications where quick and accurate dewpoint measurements have to be made. With the DPT-600 Plus, accurate spotchecks of moisture in gases can be made faster and easier than ever, over the range of -110°C to +20°C dewpoint.
Nanoporous Metal Oxide Film Sensor
PhyMetrix has developed a nanopore geometry with capillary action towards water molecules. This unique structure creates equilibrium between the inside and outside of these pores such that the concentration of water molecules inside the pores is exponentially proportional to the concentration of water molecules outside the pores. Thus the capacitance change due to a small change in water molecule content in the gas is significant enough to produce a repeatable measurement. The following graph depicts the sensor response to partial water vapor pressure of approximately 17 (nF) per decade of partial water vapor pressure (mB).
Advantages
The ability of the sensor to attract large amount of water molecules when the moisture content is very low (e.g. parts per billion), creates a sensor capable of very reproducible fast responding measurements at dewpoints as low as 110°Cdp. The response time is further enhanced in the PhyMetrix portable instruments by the desiccant sensor storage mechanism. The ability of our Analyzer to have a built-in temperature and pressure sensors to perform compensations provides a calibrated consistent measurement. The NIST traceable calibration performed on each instrument at the PhyMetrix Calibration Laboratory provides an accurate measurement. The advanced humanfactors engineered software and ergonomic housing allows easy use.
