A bus bar among main elements configuring a voltage sensing assembly is disposed in a frame configuring a short side among four frames configuring the first cartridge, and a sensing wire among the main elements configuring the voltage sensing assembly is disposed in two frames configuring a short side and one frame configuring a long side among four frames configuring the second cartridge.

Disclosed herein are delayed reaction threshold temperature indicators and methods of making and activating the same, the delayed reaction threshold temperature indicators including a first substrate, first and second layers, and a housing secured to the substrate. The first layer includes a first reactant and an optional meltable polymer, and the second layer includes a meltable polymer and a second reactant. The meltable polymer is configured to keep the first and second reactants from interacting with each other. When exposed to temperatures at and/or above a desired threshold for a period of time, the meltable polymer melts and allows the first and second reactants to come into contact with each other, thereby producing a visual change in appearance.

A temperature monitoring system for monitoring a temperature status of an item from a location different than a location at which the item is located is disclosed. The temperature monitoring system includes a base having a top surface and a bottom surface, and a first unit removably engageable with the top surface of the base in at least a first orientation and a second orientation. The first unit is configured to monitor a measured temperature, to display information regarding the measured temperature, and/or to transmit temperature information to a user device. The temperature monitoring system may also include at least one thermal or temperature probe configured to measure the temperature of the item, including a probe tip, probe wire, and probe plug. The temperature monitoring system may also include one or more probe supports configured to releasably attach to the base and configured to releasably retain a thermal probe thereon.

A remote temperature monitoring system includes a temperature monitoring device and a remote monitoring platform. The temperature monitoring system uses a temperature acquisition sensor to process collected temperature data in a single-chip microcomputer, and then the processed data information is transmitted to a computer by the single-chip microcomputer. Monitoring software is installed in the computer. After the software obtains the data, the data are parsed, and then a temperature-time map is presented in a visual interface. At the same time, the temperature monitoring device also transmits the parsed data to the remote monitoring platform, thereby realizing remote monitoring of temperature. The system integrates multi-channel acquisition, remote monitoring, timed temperature measurement, real-time mapping, data storage, temperature alarm and other functions into one.

A remote temperature monitoring system includes a first unit operatively connected to one or more temperature sensors for sensing the temperature of one or more materials or food items being cooked or heated. The first unit transmits the sensed temperature to a second unit that is located remotely from the first unit during heating. The second unit is programmable with the desired temperature and/or heating parameters of the item. By monitoring the temperature status of the item over time, the system determines when the food has reached the desired temperature or degree of cooking, and notifies the user.

A surveillance platform for the sensing, measuring, monitoring and controlling equipment and environments, such as food storage and retailing environments, data center environments, and other environments in which equipment performance, operating status, and environmental condition monitoring is desirable, is provided. The surveillance platform can facilitate reporting, visualizing, acknowledging, analyzing, calculating, event generating, notifying, trending, and tracking, of operational events occurring within the environment. Such techniques can be used to protect articles such as food articles, medical articles, computing devices and equipment, artifacts, documents, and the like.
