The measuring dispenser consists of a base element having a container element inserted therein where both elements are of cylindrical construction and can be rotated relative to each other. The base element has a bottom end which has measuring chambers to hold granular material to be dispensed. The container element holds the supply of granular material which fills the measuring chambers through a fill opening. A dispensing channel in the container element is designed to be positioned over a mea...

A measuring device, such as a ruler, tape measure, etc. includes a first edge defining a first region having a first set of indicia corresponding to a first linear scale, and also includes a second edge defining a second region having a second set of indicia corresponding to a second linear scale. Advantageously, each set of indicia consists of hash marks and corresponding numerical values printed or etched on the measuring device. The first linear scale may be actual, e.g., the indicia are spac...

A measuring unit for use in a sensor utilizing the phenomenon of attenuation in total internal reflection includes a dielectric block which is transparent to a light beam and has a flat and smooth surface on which a film layer is formed, and a flow passage member held in close contact with the film layer. The flow passage member is provided with a passage comprising a supply passage extending from an inlet of the flow passage member to a measuring portion and a discharge passage extending from t...

The measuring array with an earth connection point (5) for determining the insulation resistance (R.sub.iso) of an energized electrical apparatus or of an installation with a supply voltage U.sub.B with a positive pole (6) and a negative pole (7), two switches (S.sub.1, S.sub.2) or a corresponding two-way switch being provided for creating a current path between one of the two poles and said earth connection point (5) in order to determine the insulation resistance (R.sub.iso) generally obtained...

A measuring device has one or more vessels with an adjustable capacity. The vessel is made of a flexible material with a peripheral hinge. The peripheral hinge enables the vessel to be reconfigured from one configuration having a first holding capacity to a second configuration having a different holding capacity.

A measuring device, in particular, an electrochemical sensor, has a sensor element arranged at a measuring point. The sensor element is arranged in a housing and is connected via electrical connecting lines to an evaluation circuit away from the measuring point. The electrical connecting lines are run, at least in the vicinity of the measuring point, in a protective device. The protective device forms a sealing seat with the housing. The housing in the area of the sealing seat, at least in some ...

A measuring device including a gage having a dial, a pointer associated with the dial, and an actuator stem operatively coupled to the pointer; and a coupling mechanism having a connector portion detachably secured to the actuator stem; and a receiver portion defining a recess having first and second longitudinally extending, transversely spaced apart and parallel support surfaces. Also included is a probe pin disposed in the recess, the probe pin being longitudinally aligned with and supported ...

An instrumentation amplifier for absolute voltage amplification having a balanced voltage inlet and a balanced voltage outlet. The voltage inlet is coupled to first amplification units having a very high open-loop gain, and which is further coupled with a feedback network provided between the outputs and second inputs of the amplification units.

A measuring apparatus (1) for measuring physiological and/or chemical and/or physical properties of at least one living cell (3) contains, in addition to further sensors (4.1, 4.2), a plurality of optical sensors (4) on a support (2), particularly a support made of semiconductor material. By means of a controller (6) and a switching facility (8) which are integrated on the same support (2), the individual optical sensors (4) and the further sensors (4.1, 4.2) can be selectively interrogated. An ...
