Multi-parameter monitoring tool assembly

A multi-parameter monitoring tool assembly, comprising:

• a sensor head configured with a plurality of sensor ports, where each of the plurality of sensor ports is configured to engage and interconnect with an interchangeable sensor head component;
• and
• an electronics housing assembly comprising a plurality of housing layers, wherein one or more of the layers are connectable to the sensor head, said electronics housing configured to enclose at least one electrical component which is electrically connectable to any of the interchangeable sensor head components engaged and interconnected with the sensor head.

A connector assembly connectable to a housing of an electronic assembly comprising:

• a removable backshell connectable to a portion of an electronics housing, the removable backshell is configured to provide access to a replaceable power source within the housing, wherein the removable backshell is further configured to include an electrode device connectable to the replaceable power source, the electrode device further configured to conduct power and data signals to at least one electronic component locatable within the housing;
• and
• a data quickconnect device connectable to the removable backshell so at provide an electrical connection between a remote data source and the at least one electrode device so as to establish a data connection between the remote data source and the at least one electronic component, wherein the data quick connect is further configured to be removable from the removable backshell in a manner which does not interrupt power between the replaceable power source and the at least one electronic component.

A monitoring tool assembly comprising:

• a housing configured to enclose at least one electronic component within an interior volume, wherein the housing is further configured to be connectable to at least one fluid pathway so as to provide atmospheric pressure within the interior volume;
• and
• a barometric pressure sensor positionable within the housing which is configured for providing barometric pressure readings.

A method of measuring barometric pressure comprising the steps of:

• providing atmospheric pressure to an enclosed volume within an electronics housing, wherein the electronics housing and at least one electronic component located therein are configured to monitor at least one parameter;
• and
• measuring barometric pressure within the enclosed volume of the electronics housing.
