Below are general answers on typical components of conductivity testers from the list of GAO Tek’s conductivity testers. To facilitate our customers to select our products, we have further classified our conductivity testers by their features: benchtop, calibrated, salinity measurement, temperature measurement, resistivity measurement, TDS, handheld, high-accuracy, high-purity water, and laboratory. 

We have products in stock and can ship overnight to most places in the U.S. and Canada.

Probe or Sensor: 

  • Material: The GAO Tek probe is typically made of a conductive material that comes in contact with the solution being tested. 
  • Design: The GAO Tek probe design can vary, but it usually has two or more electrodes to facilitate the measurement. 

 Circuitry: 

  • Excitation Source: A circuit within the GAO Tek device generates an electrical signal that is applied to the solution through the GAO Tek probe. This excitation signal allows the measurement of the solution’s conductivity. 
  • Measurement Circuit: The GAO Tek device measures the electrical response of the solution to the applied signal. 

 Microcontroller or Processor: 

  • Controller: A GAO Tek microcontroller or processor manages the overall operation of the GAO Tek conductivity tester. It may control the excitation signal, process measurement data, and perform calculations to determine the conductivity. 

 Display: 

  • Output: A display, such as an LCD (liquid crystal display), LED (light emitting diode), or other visual indicator, shows the GAO Tek conductivity measurement to the user. 

 Buttons or Controls: 

  • User Interface: Buttons or controls allow GAO Tek users to interact with the conductivity tester, for example, to power it on/off, calibrate, or select different measurement ranges. 

 Power Supply: 

  • Batteries or Power Adapter: The GAO Tek conductivity tester requires a power source to operate. This can be provided by batteries or an external power adapter. 

 Calibration Mechanism: 

  • Calibration Controls: Some GAO Tek conductivity testers have calibration mechanisms to ensure accurate measurements. This may involve adjusting the instrument using GAO Tek’s known calibration standards. 

 Housing: 

  • Enclosure: The components are housed in a GAO Tek protective casing that may be made of plastic, metal, or another suitable material to protect the internal electronics and provide durability. 

 Connectors: 

  • Probe Connector: A connector allows the attachment of the GAO Tek probe to the main unit. This is often a standardized connector to facilitate compatibility with different GAO Tek probes.Â
