Item # Model 415 D1 or D2, Model 415 D1 or D2, Trace Oxygen Analyzer with cabinet purge systems for hazardous areas


The Nova FLEXI-NOVA Series Platform has been designed for continuous gas measurements in applications and environments that are less intensive. Lab work, research, clean processes, pre-treated / pre-cleaned produced gases, and others, may benefit from the FLEXI-NOVA series.

Depending on application, some light-duty sample conditioning features may be available. For clean process measurements, PPM-level O2 gas. This electrochemical type sensor is unaffected by most other gases in the sample including most hydrocarbons and acidic gases such as carbon dioxide (CO2), hydrogen sulfide (H2S), and sulfur dioxide (SO2). Typical O2 sensor life is 1-2 years or longer depending on measurement concentrations and sample gas exposure. The sensor may be easily replaced by the customer.

All sensors / detectors are temperature-controlled or temperature-compensated for maximum analytical stability. Easy calibration using touch-screen controls. Serial Output Package allows connection & data-logging to personal computers via a choice of USB / RS-232 / RS-485.

Cabinet: NEMA 4 cabinet with Hazardous Area Purge System; available for Class 1 Div1 or Div2 hazardous areas.

Specifications

Method of Detection
Customer replaceable 'fuel cell' oxygen sensor

Ranges Available
Any range between 0-100 PPM and 0-10000 PPM

Resolution
1 PPM

Accuracy & Repeatability
±1% of full scale

Drift

Linearity
±1% of full scale

Size & Weight
Dimensions will vary depending on type of cabinet purge required
NEMA 4: 51H x 41W x 26D cm (20"H x 16"W x 10"D)

Power
115 VAC, 60 Hz
220 VAC, 50 Hz

Output Options

Low flow alarm

Analyzer Type
O2 Analyzer

Hazardous Area Rating Options
Class 1 Div 2 or Class 1 Div 1 Hazardous Area Ratings available


Applications
Light-duty analyzers for applications or environments that are less intensive. For continuous analysis of PPM levels of oxygen (O2) in clean / dry gas streams. Applications include blanketing mixtures, glove boxes, electronics, research, hydrogen/nitrogen mixtures, and many others.


Features
  • Bright digital readout in PPM O2
  • Ranges available from 0-100 PPM to 0-10000 PPM O2
  • Unaffected by hydrocarbons in the sample
  • Easy-to-maintain, modular layout
  • Built in sample pump or pressure regulator, and 4-20mA outputs
  • Manual or solenoid valves trap nitrogen (N2) in cell to avoid depletion when analyzer is powered off
  • Touch-screen display for gas readings and for start-up programming at installation time
  • Magnetic switch allows subsequent calibration without needing to open cabinet door


Options
  • Hi/Low gas and low flow alarms available
  • Serial output available
  • Light-duty pre-filter & condensate removal
  • Up to 6 other gases measured (depending on application)
  • Cabinet cooling available


Calibration
  • Nitrogen for zero
  • Air or analyzed calibration gas for span


Unique Applications
The O2 sensor in the Model 415 is not normally affected by gas stream composition. However, continuous or frequent exposure to high levels of acid gases such as carbon dioxide (CO2) and sulfur dioxide (SO2) can cause decreased cell life. All Nova analyzers are built using proven technologies and techniques. If this product does not suit your application, please contact Nova at 1-800-295-3771. In many cases, we are able to build an analyzer specific to your needs.
