Embodiment Construction

[0008] Such as figure 1 Schematic diagram of the structure of the precision chilled mirror dew point meter of the present invention. The precision chilled mirror dew point meter includes a temperature probe, a sampling system, a heat dissipation system and a portable case. The temperature probe is a sensor probe with a dual optical path system. The probe also includes a condenser mirror and a beam splitter mirror. As well as scattered light, no light is wasted, the light acceptance of the high-sensitivity sensor is guaranteed, and the sensitivity of the measurement is significantly improved. The design of the beam splitter compensates the temperature of the incident light, even if the ambient temperature is different, it can also ensure that the intensity of the incident light is constant, and then Guaranteed measurement accuracy.

[0009] The sensor probe also includes a microscope, which is used to observe the occurrence and disappearance of the water layer, and take necess...

Abstract

The invention provides a precision cold mirror dew point meter, which comprises a temperature probe, a sampling system and a radiating system. The temperature probe is a sensor probe of a double optical path system and comprises a condensing lens and a spectroscope; the condensing lens focuses incident light, radiation light and scattered light; and the spectroscope performs temperature compensation on the incident light. The sensor probe with temperature compensation property is adopted, so the measuring precision of the dew point meter can be ensured at various environment temperatures.

Description

technical field [0001] The invention relates to a dew point meter, in particular to a precision chilled mirror type dew point meter. Background technique [0002] A dew point meter is an instrument for measuring the moisture content in a gas. At present, precision dew point meters in the world mainly use mirror condensation dew point meters with photoelectric detection and thermoelectric cooling. However, due to the production of supercooled water, the Kelvin effect of the phase interface, and the impurities on the mirror surface, the measurement accuracy of the dew point meter is affected, which hinders the development of the dew point meter technology. How to effectively reduce the influence of these adverse effects and obtain a dew point meter with high precision is an urgent problem to be solved at present. Contents of the invention [0003] The purpose of the present invention is to provide a precision chilled mirror dew point meter, improve the structure of the chi...
