摘要： A portable, small-sized device is provided to accurately conduct a leakage test for a liquid volume meter such as a pipette. In operation, pipette P is connected to the device main body side via a tube. A command from a central processing unit causes a pump to perform a suctioning operation to depressurize the pipette P side to a predetermined pressure. Any pressure changes over a predetermined period of time are monitored by a pressure sensor. The central processing unit determines whether there is leakage from the pipette P, and displays a judgment result on a display unit. In particular, when a diaphragm pump is used as the pump, the pulsation of an air flow occurring in a suction operation is attenuated in a pressure vessel so as not to have harmful effects on either the inspection results or the pipette P side.

摘要： For easy centralized management of measurement data and installation environmental data and user's real-time recognition through a certain type of peripheral equipment of how the installation environment affects the measured values at the site of measurement, a data logger for a measurement device includes in its structure any of the sensors for temperature, humidity, air pressure, and acceleration as an environmental sensor that detects a physical quality of an environment where the measurement device is installed, a data recording unit that records installation environmental data detected by the environmental sensor and measurement data detected by the measurement device on the basis of time, and a data processing unit that displays the installation environmental data and measurement data in whole or selectively, as numerical values or graphs of changes over time, with the time axes aligned, and includes one or more external equipment terminal connectors that exchange signals with external equipment.

摘要： An annular sealing material seals a pipe joint between a socket and a spigot. The sealing material includes a bulb part which is composed of a first bulb, a second bulb located closer to the inner side of the socket than the first bulb, and a narrow part present between the first and second bulbs. The first bulb is pressed against the inner circumferential surface of the socket. The second bulb is pressed against the outer peripheral surface of the spigot. The second bulb is inclined towards the pipe center from the first bulb in a natural state before it is provided between the socket and the spigot. The inner diameter of the second bulb is smaller than the outer diameter of the spigot in the natural state. The second bulb is extensible in the pipe diameter direction due to elastic deformation of the narrow part.
