• Other environmental analysis equipment

This is a thermocouple wire that has a structure in which a thermocouple element is electrically insulated with a filler material sealed inside a metal protective sheath (sheath). It is mainly used in harsh measurement environments such as high-temperature regions, extremely low-temperature environments, high-pressure conditions, and vacuum atmospheres, where standard insulated thermocouple wires are difficult to handle. It is necessary to select the sheath diameter, sheath material, type of filler, and the thermocouple element installed inside the sheath according to the measurement environment.

• Temperature and humidity measuring instruments

Thermocouple wires made from materials specified by international industrial standards tend to be expensive, and wiring and installing thermocouple wires and the coated thermocouple wires from the measurement point to data loggers and other measuring instruments is a significant burden in terms of actual work and costs. Compensation wires are made from less expensive metal wires that have thermal electromotive force characteristics almost equivalent to those of the thermocouples used, and like thermocouple wires, they are standardized in various countries, requiring the selection of compensation wires that are compatible with the types of thermocouple wires.

• Temperature and humidity measuring instruments

In a thermocouple, the point where different metals are in contact (the junction) becomes the measurement point. When using uncoated thermocouple wires, it is necessary to devise a way to ensure that each wire does not touch anywhere other than at the measurement point. To alleviate this inconvenience, thermocouple wires that are coated with materials such as Teflon are referred to as insulated thermocouple wires. ■ Insulated single wire for thermocouples (single type) This is a thermocouple wire that has been coated with insulation. It provides ease of handling for thin thermocouple wires and also serves to protect the wire metal, which is susceptible to chemical reactions. Materials available include Formvar (enamel), Teflon (PFA), and Ceramo (ceramic). ■ Double insulated thermocouple wire (duplex type) This consists of two single type insulated thermocouple wires, one for the positive side and one for the negative side, arranged in parallel and further coated to create a two-layer structure, also known as parallel wire. This type is even easier to handle than the single type, and the overall strength of the thermocouple is improved. The junctions are also easier to manufacture.
