What is a dew point meter?

A dew point meter is an instrument that can directly measure the dew point temperature. A mirror is cooled in the humid air of the sample until the moment when dew droplets (or ice crystals) are looming on the mirror, and the average temperature of the mirror is measured, which is the dew point (frost) temperature. It has high humidity measurement accuracy, but requires a mirror surface with high smoothness, a temperature control system with high precision, and an optical detection system for dew droplets (ice crystals) with high sensitivity.

Gases with different moisture content will condense on the mirror surface at different temperatures. Using photoelectric detection technology, the exposed layer is detected and the temperature when dew condensation is measured, and the dew point is directly displayed. The methods of mirror cooling include semiconductor refrigeration, liquid nitrogen refrigeration and high-pressure air refrigeration. The mirror type dew point meter adopts the direct measurement method. Under the premise of ensuring accurate dew detection, high mirror cooling efficiency and precise measurement of condensation temperature, this kind of dew point meter can be used as a standard dew point meter.

Dew point meter features

One character of the meter is its high accuracy of humidity measurement. For this feature, it requires some conditions: a mirror surface with high smoothness, a temperature control system with high precision, and an optical detection system for dew droplets (ice crystals) with high sensitivity. When using it, the pipe that sucks in the sample air must be kept clean, otherwise the impurities in the pipe will absorb or release moisture and cause measurement errors.

And other characteristics of the dew point meter are as fallowing.

• It can display multiple humidity parameters, such as dew point/frost point temperature, relative humidity, moisture or dry gas volume and ambient temperature.
• The measurement data is displayed on the LCD display in digital or graphic form. The output readings can be converted into real-time graphs with the push of a button.
• Easy to use user interface, fixed keys refer to graph, hold/store and record keys.
• On-site data can be recorded, up to 2700 points.
• The structure is light and strong, with waterproof and dustproof shell protection. The dew point meter can be used stably in extremely harsh environments and is suitable for various occasions.
• The battery can enable the meter to be used outdoors for a long time.

Dew point meter applications

If you know where a dew point meter can be used, you will be more aware of whether you need to buy a dew point meter.

Marine Weather Measurement:

Safety, protection and efficiency are the most important requirements in maritime operations on board and ashore. Reliable environmental measurement and monitoring is critical. This ensures safe operation in ports, ships and offshore platforms.

Port:

The unique challenges facing the port are related to both the surrounding environment and the prevailing weather conditions. The ocean's weather is constantly changing, and sometimes there are localized weather changes. Such conditions continuously affect port operations and safety. For example, due to the weather, ships are often unable to call in ports. Helicopter operations are limited by wind speed, visibility and lightning conditions. Cargo handling, ship berthing, driving, towing and dredging operations were also affected by severe weather.

A variety of weather and sea conditions parameters, including wind, fog, rain, water level, waves, and currents, directly affect various operations. Accurate observation, analysis, and communication of local weather and sea state information helps port users make the right decisions at the right time. In all important operations, with useful weather information, operations can be carried out safely.

Sea traffic:

Severe weather and rough sea conditions have challenged the ability of ships to navigate safely. An important requirement of ship operation is to promise the safe passage of waterways and the efficiency of transportation. Therefore, it is important to obtain local meteorological/hydrological information. Only accurate and timely information can ensure unimpeded operations, improve maritime safety, increase navigation efficiency, and assist the ship's decision-making process. The role played by the dew point meter cannot be underestimated.

Measure compressed air:

If the dew point measurement is also accompanied by pressure measurement, it can bring more advantages. When the dew point measurement data is combined with the real-time pressure value, the atmospheric pressure dew point and the ppm volume ratio can be output online in real time, without the ambiguity of the dew point value caused by different pressures. For medical gases, for example, the measurement requirements specified in the standard can be quickly and easily accomplished.

The dew point meter is installed in the compressed air line and has not been calibrated or adjusted. The entire pipeline truly restores the instrument gas environment. With accurate dew point measurement, energy consumption can be reduced by up to 20%.
