PROBLEM TO BE SOLVED: To provide a new-configuration multiple gas monitors simultaneous calibration device and an update processing method for a gas monitor, capable of simultaneously calibrating all of the plurality of portable gas monitors, performing a series of updating processes in a short time, and having high convenience. SOLUTION: This simultaneous calibration device comprises: a plurality of calibration modules connected such that calibrating gas is sequentially supplied; and a device body having a control mechanism performing information processing and operation control of each part. Each the calibration module is provided with a conduit opening/closing valve in a supply side gas conduit, and is provided with a check valve in a discharge side gas conduit. The check valve has a valve element closing the gas conduit by its own weight and opening the gas conduit by pressure of the gas. Each the calibration module has an information communication function once recording information about the gas monitor into a recording means provided in the module and transferring it to the device body, and is provided with a charging output terminal.
