Help with Dissolved Oxygen Sensors specifications:

Cell Type
   Cell Type      The term “dissolved oxygen sensor” refers to the entire sensor assembly, including the electrodes, electrolyte solutions, membranes, and thermistor thermometers.
   Your choices are...         
   Polarographic       Uses an external voltage. The difference in potential between the cathode and anode is less than 0.5 volts. Can be Ross or Clark Polarographic types. 
   Galvanic       No external voltage is required. The difference in potential between the cathode and anode is greater than 0.5 volts. Galvanic probes are more stable and more accurate at low dissolved oxygen levels than polarographic probes. Galvanic probes often operate several months without electrolyte or membrane replacement, resulting in lower maintenance cost.

Performance Specifications
   Oxygen Range:       Full range of oxygen concentration required to measure. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Accuracy:       Required Accuracy in percent of full scale. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Response Time:       Typically time to reach 95% of final value. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Minimum Flow Rate:       Minimum flow rate of the aqueous solution through the sensor. In all DO probes, the membrane/sample interface should have a few cm/sec flow of the sample for precision performance. Without flow at the interface, the surrounding oxygen will be consumed and the local reading drops. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.

Mounting Options
   Mounting Options       
   Your choices are...         
   Hand Held or Portable       Typically used for laboratory purposes. 
   In-Line (Insertion)       Insertion/retraction without disturbing flow; includes "side stream". 
   Flow Thru (Pipeline)       Integral flanges or other pipe connection; directly into existing pipeline. 
   Other       Specialized or unlisted option. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Features
   Disposable Membrane Cap?       A disposable membrane cap is used to keep the sensor clean to improve accuracy and reduce maintenance time and cost. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Built-in Temperature Sensor?         
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Temperature Compensated?       Automatic adjustment for the change in permeability of the membrane and solubility of oxygen in water as a function of temperature. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
