What is the usual maximum air pressure for a home pressure cooker

Usually the maximum air pressure of home pressure cooker is 1.2 atmospheres. At this pressure, the boiling point of water is close to 120 degrees Celsius, and the higher the temperature, the faster the food cooks.

The pressure cooker, also known as a pressure cooker, with which the food to be steamed can be heated to more than 100 degrees Celsius, was invented in 1679 by the French physicist Denis Papin. It greatly shortens the cooking time and saves energy with its unique high-temperature and high-pressure function; however, pressure cookers that work under high pressure are also more destructive to nutrition.
