Abstract:
Described herein is an insertion mount, including a threaded cylindrical mount with a hollow inner diameter and a lengthwise slot cutout for receiving a probe; and a drive assembly further comprising a drive nut, wherein the drive nut has threads that engage the threaded outer diameter of the threaded cylindrical mount which allows the drive nut to be moved the length of the cylindrical mount by screwing the drive nut of the drive assembly onto the threads of the threaded cylindrical mount.
Abstract:
An ionic probe is provided according to the invention. The ionic probe includes an active electrode configured to generate a measurement signal for an external test fluid, a first reference electrode configured to generate a first reference signal, and an at least second reference electrode configured to generate at least a second reference signal. The measurement signal is compared to the first reference signal and the at least second reference signal in order to determine an ionic measurement of the external test fluid.
Abstract:
An electronic device for analyzing an aqueous solution may comprise a housing, one or more measurement circuits and a control circuit all arranged inside the housing. The housing may be configured to receive a test element. The one or more measurement circuits may be configured to produce one or more corresponding sets of measurement signals relating to an aqueous solution received on the test element. The control circuit may include a memory having instructions stored therein that are executable by the control circuit to process the one or more sets of measurement signals to determine one or more corresponding characteristics of the aqueous solution.
Abstract:
An optical gasket system for use in a calorimeter or other instrument which utilizes a light beam and a sample cell or chamber for a liquid to be tested. Each gasket is optically clear and is pliable so as to conform to the surface of the sample cell which is in the path of the light beam. The gaskets prevent moisture from condensing on the surface of the sample cell and interfering with the passage of the light beam through the cell.
