Product catalog summary
Overview
Panametrics M Series aluminum oxide moisture probes are designed for industrial moisture measurement, offering superior performance, ease of use, and a wide measurement range. These probes are coupled with Panametrics hygrometer consoles and are known for their rigorous calibration standards.

Superior Performance
The performance of the M Series probes is attributed to the critical thickness of the oxide film, which ensures true absolute humidity measurement and quick response. The probes exhibit exceptional calibration stability.

Calibration Standards
Each sensor is individually calibrated in advanced facilities using devices traceable to national standards. The calibration process involves repeated testing over months to ensure accuracy and stability.

Theory of Operation
The M Series sensor measures water vapor pressure in gases and liquids using a porous oxide layer with a thin gold coating. This setup forms an aluminum oxide capacitor, where water vapor affects the conductivity and impedance, correlating to water vapor pressure.

Installation Flexibility
The probes can be installed remotely with cable lengths up to 2000 ft (610 m) and operate under pressures from vacuum to 5000 psig (345 bar). They are available in various housings and can be used with sample conditioning systems to maintain sample integrity.

Features
  • Intrinsically safe with certified electronics or zener barriers
  • Superior sensitivity and calibration stability
  • Optional temperature sensor
  • Calibrations traceable to national standards
  • Wide dynamic range

Applications
The probes are suitable for measuring moisture in gases and non-aqueous liquids across industries such as petrochemical, natural gas, industrial gas, semiconductor, and more.

Technical Specifications

M Series-2

M Series Datasheet I PANAMETRICS Film thickness of the oxide layer is critical to the performance of this type of sensor. Panametrics manufactures sensors with an oxide film thickness that causes them to exhibit true absolute humidity, rather than relative humidity response. This critical film thickness also gives the M Series probe quick response and exceptional calibration stability. Each Panametrics aluminum oxide sensor is individually calibrated in one of the world's most advanced moisture calibration facilities. Developed over several decades, this facility uses flow, temperature and pressure...
