Moisture & Gas Analyzers

Panametrics offers a wide variety of single- and multi-stage chilled mirror sensors for moisture measurements from sub-ppm industrial and calibration applications to near-saturation at high-temperature process applications. Driving these sensors are the Optica and OptiSonde display and controllers.

Optica Chilled Mirror Hygrometer - The Optica Chilled Mirror Hygrometer is the best choice for laboratory and calibration applications where precise water vapor control of gas atmospheres is critical. Optica can measure and display on its large color display:

• Relative humidity (% RH)
• Dew/frost point (Td)
• Absolute humidity (m/v)
• Mass mixing ratio (m/m)
• Volume mixing ratio (v/v)
• Wet bulb (Tw)
• Enthalpy (h)
• Water vapor pressure (e)
• Temperature
• Pressure

OptiSonde Chilled Mirror Hygrometer - This hygrometer is the perfect analyzer of choice for laboratory and process measurements. The OptiSonde shares many of the same features as the Optica. Some features include:

• Compact and rugged design for easy installation and durability
• Patented PACER® cycle automatically cleans mirror to ensure measurement integrity
• Built-in data logger provides the ability to record historical data
• Sensor conveniently plugs into wall mount chassis for facility monitoring
• Sensors may be installed to 91 m away for remote monitoring
• Digital (RS-232) interface for data integrity
• Humidity measurements are traceable to the National Institute of Standards and Traceability (NIST)

Panametrics, a Baker Hughes business, offers our customers a broad spectrum of moisture analyzer products. Trace moisture analyzers offer intrinsically safe moisture measurement in gases and non-aqueous liquids.

Requiring no recalibration, TDLAS hygrometers also offer our customers a low cost of ownership.

The Aurora product line delivers:

• Panametrics TDLAS moisture analyzer, Aurora, provides immediate response during process upsets and rapid dry-down from wet conditions
• Aurora TransPort, offers all the features of the Aurora in a portable configuration for spot-checking and analyzer validation
• The Aurora 19 moisture analyzer configures the TDL technology in a 19” rack mount configuration for moisture in metal heat-treating furnace gas, industrial and inert gas, compressed air, testing, and calibration applications

Panametrics’ PM880 portable moisture analyzer measures the moisture content of industrial gases and liquids. The PM880 hygrometer is a complete, intrinsically safe, portable system with options and accessories to meet all industrial moisture measurement needs. This hygrometer is small, lightweight, and easy-to-use. The large LCD displays moisture readings in dew point (°C or °F), ppmv, ppmw, lb/MMSCF (natural gas), and a variety of other unit options. Data can be viewed in alphanumeric or graphic formats.

The PM880 comes in a soft carrying case with zippered compartments, a handle, and a shoulder strap. The case accommodates the PM880, a sample system, flexible hosing, probes with protective covers, an operating manual, a battery pack, a battery charger, and probe cables.

The PM880 meets the most demanding process applications, including petrochemical, natural gas, industrial gas, semiconductor, furnace gas/heat treating, power generation, air dryer, pharmaceutical and aerospace.
