Help with Dissolved CO2 Instruments specifications:

Dissolved Carbon Dioxide Measurement
   Dissolved CO2 Range       The dissolved carbon dioxide measurement range in parts per million. 
   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       The dissolved carbon dioxide accuracy of the instrument (parts per million). 
   Search Logic:      All matching products will have a value less than or equal to the specified value.

User Interface
   Display Type       
   Your choices are...         
   Analog Meter       Devices have an analog meter, typically with a needle 
   Digital Display       Devices have a digital display.  
   Video Display       Devices have a cathode ray tube (CRT), liquid-crystal display (LCD), flat panel display (FPD), or other multiline display. 
   None       Devices do not have a display. 
   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.
   User Controls       
   Your choices are...         
   Manual Controls       Devices have simple, front panel or local controls such as knobs and/or potentiometers. 
   Digital Front Panel       Devices have a digital front panel that is programmed with a keypad. 
   Computer Interface       Devices are programmed with a computer interface. 
   None       Devices do not have user controls. 
   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.

Output Options
   Electrical Output       
   Your choices are...         
   Analog Voltage Output       The output is an analog voltage. This is a simple, usually linear, function of the measurement. 
   Analog Current Output       The output is an analog current that is imposed on the output circuit proportional to the measurement. Feedback provides the appropriate current, regardless of variables such as line noise and impedance. Analog current outputs or transmitters are often used to send signals over long distances. 
   Analog Frequency Output       The output is an analog frequency, a format which transmits information with continuous physical variables such as voltage amplitude or frequency variations. 
   Switch / Alarm Relay Output       The output is a change-in-state of a switch or alarm. 
   Other Output       Other unlisted output types. 
   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 & Functionality
   Battery Powered       Devices require batteries for full operation, not just a battery backup. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Filters       Devices provide special signal processing or filtering. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Event Triggered       Devices can capture and/or log data when an event happens. 
   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 or Self-calibration       Devices have a built-in calibrator, which can be used for testing and readjustment. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Extreme Environment       Devices are designed to withstand harsh environments with extreme humidity, temperature, dust, etc. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Self-test / Diagnostics       Devices have self-test or diagnostics capabilities. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
