Medidor de Dew Point
A portable dew point meter with a stainless process probe and controlled sampling interface for checking moisture in compressed air and other non-corrosive gases.
- Portable dry-gas moisture checks.
- 316L process probe and sampling cell.
- Live stabilization trend display.
Introdução do produto
This field meter combines a battery-powered graphical indicator with a cabled stainless steel dew point probe and a compact flow-through sampling cell. The sensor can be installed directly in a compatible process connection or exposed to a regulated slipstream through the sampling cell, allowing the user to keep gas pressure, flow and ambient ingress under control. Automatic sensor conditioning supports recovery after exposure to wetter gas, while the indicator stores readings and displays trends during stabilization.
Características-chave
Stainless wetted parts and a sintered filter protect the sensor in clean non-corrosive gas streams.
Flow-through sampling cell provides a defined inlet and outlet for pressurized gas measurements.
Pressure compensation converts the measured condition to a selected reference pressure when required.
Automatic sensor conditioning shortens recovery after a high-moisture exposure.
Handheld trend display and internal logging help the operator judge when a reading has stabilized.
Preocupações do produto do cliente
Dry-gas dew point measurements are sensitive to ambient leakage, sample pressure, tubing material and stabilization time, so the sampling path must protect the reading as carefully as the sensor itself.
Ambient moisture can enter a dry gas sample and cause a falsely high reading.A sealed flow-through cell and low-permeability tubing isolate the sensor from room air during sampling.
A sensor exposed to wet gas may take too long to return to a low dew point.Automatic sensor conditioning accelerates recovery before the next dry-gas measurement.
Process pressure can make a dew point result difficult to compare with atmospheric values.Selectable pressure compensation reports the measured result at the required reference condition.
Operators may record a value before the sample and sensor have stabilized.The graphical trend and stored time series make the approach to equilibrium visible at the handheld display.
