Abstract:
A control apparatus includes a controller configured to execute a condensation prevention process for preventing condensation on a window according to an ambient temperature and humidity of a chamber and a surface temperature of the window at the inside of the chamber, the chamber including the window and housing a light receiving element configured to receive light entering the chamber from the window via a sample for measurement located in a space outside the chamber or a light source configured to irradiate light on the sample through the window.
Abstract:
An infrared spectrophotometer, which is capable of preventing measurement data measured from being adversely affected by moisture vapor. An internal space of an attachment receiving therein an optical element is sealed and isolated from ambient air by providing a tube and others, and a dehumidifier is provided in the internal space of the attachment for an optical path. Thus, the dehumidifier is disposed in a relatively narrow space, so that the internal space of the attachment can be efficiently dehumidified within a short period of time so as to reduce humidity in the internal space to suppress absorption of moisture vapor which would otherwise occur on the optical path in the internal space of the attachment. This makes it possible to prevent a negative influence of moisture vapor on measurement data, while reducing a standby time due to the dehumidification.

Abstract:
A low-cost soil gas-flux monitor provides localized sensors eliminating the need for a tethered analysis unit and permitting flexible sensor locations enabled by wireless and conduit-less interconnectivity. A housing form factor permits a low-power door actuation for venting making the necessary battery operation practical.
Abstract:
A nephelometric turbidimeter for measuring a turbidity of a liquid sample in a transparent sample cuvette. The nephelometric turbidimeter includes a cuvette chamber housing with a cuvette chamber having the transparent sample cuvette arranged therein, and a drying apparatus. The drying apparatus includes a cuvette chamber inlet opening which vents the cuvette chamber, a cuvette chamber outlet opening which de-vents the cuvette chamber, an air circulator which circulates air from the cuvette chamber outlet opening to the cuvette chamber inlet opening, and a drying body. The drying body is provided as a container of a hygroscopic agent defined by a drying substance which is arranged in a drying path between the cuvette chamber outlet opening and the cuvette chamber inlet opening so that air flows through the drying body.
