Frequency Response:

Allow up to: overrange/margin
Use the overrange/margin to restrict your search to items whose full-scale range is close to your requirements.
(Overrange/margin requires both 'From' and 'To' values to work.)

Performance Specifications
   Frequency Response       Frequency Response is the range of frequencies for which the microphone maintains a constant sensitivity within defined boundaries. Variation from this "linear" or "flat" sensitivity is given in dB; bounds that the define the linear frequency response will be in the form of ±3dB, -1dB/+4dB, etc. 
   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.
   Hydrophone Sensitivity:       Typical values range between -220 and -150; more negative values represent lower sensitivity. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Maximum Operating Depth:       This is the maximum depth for rated operation. Typically a "survival depth" will also be given that is significantly greater. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Operating Temperature:       The temperature range over which the device must operate. 
   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.

Features
   Integral Pre-amplifier?       A pre-amplifier boosts the hydrophone output from a small to intermediate level so that the signal may be further processed without significant degradation of the signal. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Acceleration Noise Compensated?       This compensation is designed to cancel or reduce noise generated from hydrophone movement underwater. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Array?       An array is a set of hydrophones wired together in series or parallel and typically towed underwater. In the case of arrays, sensitivity ratings are given for the individual hydrophones that are part of the array. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Number of Hydrophones (Array only):         
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Mechanical Specifications
   Diameter:       Diameter or maximum side dimension. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Length:       Length of individual hydrophone or of array. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Weight (air):       Hydrophone weight in air. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
