Model 201-B

201B PID Wall Mount
VOC Analyzer

201B FID 19" Rack Mount
VOC Analyzer

• Three Detector Options
  Offers a custom-engineered solution for your specific application- PID, FID or TCD
  
• 19" Rack Mount, Bench Mount or NEMA Enclosure (G.P., Class 1, Div 1, or Class 1, Div 2)
  Provides flexibility whether you require a system that is compact for rack or wall-mounted for fixed site monitoring
  
• New Improvements & Features
  Automatic calibration , lamp or FID out, power or pump failure, linearized output provides extended linear range, digit LED readout eliminates need for range switch, improved sensitivity (high sensitivity model available) for special applications
  
• Numerous Signal Outputs
  Integrates easily into your existing instrument data network through 4-20 mA, RS232 or 0-1V output; dual set point option for process control, interface to process computer
  
• Continuous, Reliable, and Linear Signal
  Easy to read and calibrate throughout the detection range.
  
• Optimal Detector Design
  Minimizes need for periodic adjustments and maintenance.

• Response Time for PID or FID in less than 1 Second
  Assures rapid detection and alarm, if necessary, of gas concentrations.
• Applications
  VOC's in Carbon bed breakthrough, VOCs (total hydrocarbons) in stacks, leak detection, hydrocarbons, chlorinated hydrocarbons, NH₃, H₂S, Cl₂,H₂, He, N₂...Total VOC's in water (requires sparger Model 650 option)
  
• Wide Dynamic Range
  Linear from 0.1 to 3000 ppm; higher levels can be monitored
  
• Multi-point Option
  Lets you monitor multiple points inexpensively with a single detector. Two point, four point or use with our MP2000 (10 or 20 points).
  
• Sparging Option
  Provides the capability to monitor VOCs in waste water from ppb to > 1000 ppm. Available with PID or FID.
