Lie detector tests are not 100% accurate and although given by law they are not admissibly in a court of law and using a lie detector is not used for public use; therefore it would not make any point for your wife to take a lie detector test. Hypothetically, if your wife did cheat she would probably decline taking the test.
There are many procedures for administering a good lie detector test. The biggest thing that needs to be done is to ask many questions to make sure the results are accurate.

In 1920, the price of a lie detector would have varied depending on the specific type and complexity of the device. Polygraph machines, which are commonly associated with lie detectors, were first developed in the early 20th century. These early versions were likely custom-built and would have been relatively expensive due to the specialized technology involved. However, without specific historical pricing data, it is challenging to provide an exact price for a lie detector in 1920.
