The document provides information about dew point meters used for measuring humidity in compressed air and gases, emphasizing their importance in ensuring proper measurements. It details the operation of these devices, which detect dew formation by cooling a mirror and measuring reflected light, and outlines their applications in industries and on ships to prevent cargo condensation damage. Additionally, it highlights the credibility of the brand 'Vasthi' in supplying reliable measuring instruments for various process industries.

2. Dew point meters and measurement gear for compressed air and gases. the
choice of the best measuring device is decisive for proper dew factor
measurement and humidity measurement in compressed air and gasoline.
specialists around the world agree with the dependable dew point measuring
gadgets from cs units.
what is the dew point meter
✓air / compressed air:
✓carbon dioxide (co2)
✓argon (ar): ✓hydrogen (h2)
✓nitrogen (n2): ✓oxygen (o2)

3. Dew point meter principle
By cooling at regular strain if the temperature of air is reduced, the water-
vapour in the air will start to condense at a particular temperature. this
temperature is known as dew point temperature.

5. ⦁ The primary elements of association are
⦁ A glittery surface (replicate) is fixed with a
thermocouple.
⦁ A nozzle is supplying a jet of air at the replicate.
⦁ A mild source centered continuously at the mirror.
⦁ A photo mobile to stumble on the amount of mild
contemplated From the reflect.
DESCRIPTION

6. OPERATION OF DEW POINT METER
The mirror is constantly cooled through a cooling medium. the cooling medium is
maintained at a constant temperature.
To this replicate is hooked up a thermocouple whose leads are connected to a
millivoltmeter.
Constantly a mild is made to fall in an attitude on the reflect and the amount of
meditated light is sensed by a photograph cell.

7. Now an air jet is made to fall in an perspective at the replicate and the water-vapor
(moisture) contained within the air starts off evolved condensing At the replicate and that
they appear as small drops (dew) on the reflect.
This moisture (dews) formed at the mirror reduces the amount of mild contemplated
from the reflect and it's far detected by using photocell. while for the first time, there is a
change in quantity of transmitted mild; it turns into an illustration of dew formation.
At this instance (this is, while the due formation is detected first), the temperature
indicated by the thermocouple attached to the mirror turns into the dew factor
temperature.

8. Accordingly this Association is used to decide the time at which the dew
seems for the first time and dew point temperature.
Software of dew factor meter
This instrument is used on ships to shield cargoes from condensation harm
by using preserving the dew factor of air in holds lower than the cargo
temperature.
Utilized in industries for figuring out dew factor.

9. USES
This instrument is used on ships to protect cargoes from condensation harm by means of
maintaining the dew factor of the air in the holds underneath the temperature of the
shipment. utilized in industries to determine the dew factor.

10. Dew point may be calculated the usage of the air
temperature and a relative humidity price, that is
measured the use of something referred to as a sling
psychrometer. ... a sling psychrometer measures
relative humidity by way of measuring
temperatures: the actual air temperature (dry-bulb)
and something known as the moist-bulb
temperature.
