Embodiment 1

[0013] See figure 1 and figure 2 . figure 1 It is a structural diagram of the present invention. The dew point meter in the present invention includes two parts: a probe and a hand-held meter, and the meter shell meets the IP65 standard, which can effectively prevent splashing and dust from entering the inside of the meter. The probe part has a probe heating device, the temperature of which is adjustable, including at least three adjustment gears: heating dew gear, degreasing gear and high temperature impurity removal gear. The user can select the required adjustment gear through the user interface of the hand-held watch. corresponding operation. Among them, the temperature of the heating and removing gear is based on the ambient temperature of the probe, heating 11°C to 15°C; the temperature of the degreasing gear is between 180°C and 200°C; between.

[0014] figure 2 is a flowchart of the present invention. The user selects the adjustment gear through the user opera...

Abstract

A dew point instrument that is suitable for chemical gas environment comprises a probe, a hand-held meter, and a probe heating device, wherein the instrument housing is in accordance with IP 65 protective standard; the temperature of the probe heating device can be adjusted, and the probe heating device is composed of at least three adjusting gears of a heating and dew removing gear, an oil stain removing gear, and a high temperature impurity removing gear; and the hand-held meter comprises a user operating interface which provides a menu for selecting the adjusting gear of the probe heating device. The present invention has the advantage that dust and particles deposited on the probe can be effectively removed to guarantee the accuracy of measurement by the dew point instrument.

Description

technical field [0001] The invention relates to a dew point meter. Background technique [0002] In chemical gases, there are often more granular substances and chemical substances that are easy to attach. Even in the normal use environment, as the use time increases, dust, chemical substances and other pollutant particles in the gas will also deposit on the probe of the dew point meter, resulting in a large error in the measurement results of the dew point meter. To solve these problems, on the one hand, it is necessary to enhance the sealing performance of the instrument; on the other hand, the instrument is required to have a chemical substance removal function, which can deal with the pollutants that have been deposited on the probe. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, solve the problem of probe contamination, so that the dew point meter can work normally even in the chemical gas environment with many...
