The Maintenance of good health depends inter alia on the correctly matched ratios of temperature and humidity, which allows to maintain the necessary microclimate in the room. The control of these parameters can be done using a special instrument called a thermometer and hygrometer. The latter is used to calculate the relative humidity of the air, but it is possible to determine the temperature. In this paper, we consider the instruction on application of the hygrometer psychrometric VIT-1.

The Concept of this type of devices

instruction manual hygrometer psychrometric VIT-1

The operation of the hygrometer psychrometric VIT-1 is based on the this device has two thermometers, on the basis of the testimony which the difference is calculated. One of them is dry, and the second — humid.

The ambient Temperature is measured constantly, wherein one of the thermometers is distilled water, therefore these two devices show different temperatures. The difference generated between the data of these two devices is one of the parameters comprising the relative humidity.

To the base of the attached hygrometer thermometers, feeder, filled with distilled H2Oh, a special psychrometric chart which determine the relative humidity.

Security Measures

Hygrometer psychrometric VIT-1

Let's Start the review of the guidelines for use of the hygrometer psychrometric VIT-1 with consideration of measures that will avoid hazards when working with this device. During installation and operation the device must not be exposed to excessive shocks; do not RUB various chemical liquids of the scale of thermometers and psychrometric chart; overheating thermometers more than 45OC, which can lead to the destruction of their tanks.

The Hygrometer psychrometric VIT-1 and VIT-2 differ in this case, the heating temperature for the last device it should not exceed 60OC. Also, it is distilled water contains toluene, which is the destruction of components of the devices of the hygrometer is necessary to remove with hot water for FREE, as it is a toxic and flammable substance.

Preparing

manual for hygrometer psychrometric VIT-1

Instructions for use hygrometer psychrometric VIT-1, as well as any other device that includes the binding section.

This training must start with unpacking the device, in order to compare the completeness of the passport. Feeder hygrometer psychrometric VIT-1 is removed from the base, then filled with distilled water. This procedure is carried out by immersing the feeder in a container of water, and the sealed end should be facing down.

Then return it to the place and placed so that from the reservoir of the thermometer to the open end of the feeder was at least 2 cm, the wick should not touch the latter. When transferring feeder in working position water from the feeder moisten the wick and the reservoir of the wet thermometer.

A Hygrometer is placed at eye level looking at him. Installation is done on a flat place without vibration, next there should be various sources of heat and cold, which would create a temperature difference between the main and reserve tanks are more than 2OC.

When using the data, psychrometric tables, which is attached to the base of the hygrometer, must maintain a certain speed aspirating flow, washing the device. It is measured before the definition of relative humidity by using an anemometer vane V5. The obtained values are rounded to tenths. Relative humidity determine when a stable reading of thermostast that form the basis of hygrometer.

Consider the manual hygrometer psychrometric VIT-1.

Carry out the readings on the two thermometers. The scale in the reference point should be straight toward the eye of the beholder. Breathe into these devices during counts impossible. First define a few tenths of a degree, and then — integers.

The Temperature is determined with an accuracy of one tenth of a degree, adding to the indications of the amendments of passports for the device by their addition. Calculate the difference between these two indicators. On a psychrometric table at the intersection of the temperature in the dry device and the resulting difference determines the relative humidity.

If in the passport there is no amendment to or received from the temperature difference, then carried out linear interpolation of the neighboring values.

Thus, we examined how to use a hygrometer psychrometric VIT-1.

Possible failures and remedial measures

Hygrometer psychrometric VIT-1 and VIT-2

Manual hygrometerpsychrometric VIT-1 also includes such a section. As part of this device is glass, so it is impossible to hit and drop. If the feeder is destroyed, it must be replaced by the new, with remnants of the old should be removed completely. If there are gaps of a liquid in thermometers, eliminate them according to the passport.

Maintenance

How to use a hygrometer psychrometric VIT-1

The Feeder should always be filled with distilled water. It is poured or after the measurements or at least half an hour prior to their implementation.

You Can use the boiled water with an exposure for at least 15 minutes. It is poured into the feeder, previously cooled to room temperature.

The Wick moistened device must be clean, damp and soft constantly. The extent of pollution it podlejit replacement. Before this procedure removed the old wick, and the tank is wiped with a swab, previously moistened in warm water. The new wick needs to have a length of 6 cm wetted in one of those waters that are listed in the beginning of this section, and then pulled on a tank so that over it the knotted end of the wick was not less than 0.7, see It tightened over the above specified device is a loop of thread making last. Another loop to tie the wick under the tank, and it must constantly correct to the reservoir obligors tightly. The loop is tightened so as to provide the capillary wetting of the fabric.

A New wick can be made of different fabrics pretreatment - washing in soda solution, boiling and rinsing. Then sew it, depending on the diameter of the tank, engine, seam height after clipping, not more than 1.5 mm.

The Initial instrument calibration is performed when shipped from the factory and then — 1 every two years.

In conclusion

This article provides instructions for use of psychrometric hygrometer VIT-1. This device can be operated at temperatures from -5 to +25 degrees. Determine the relative humidity on a psychrometric table, at the intersection of the dry bulb temperature and difference between wet and dry.
