IVA-6N thermohygrometer

It is intended for measurement of relative humidity and air temperature in inhabited, warehouse and production rooms, and also in the free atmosphere.

---

IVA-6N scopes:

• measurement of parameters of a microclimate of inhabited and production rooms, including in the museums, archives, libraries, drugstores, testing laboratories;
• certification of workplaces in the centers of labor protection and TsGSEN;
• control of parameters of a microclimate in pure production rooms of pharmaceutical and electronic industry;
• control of humidity of air in the printing industry;
• control of storage of production.

• The thermohygrometer consists of the block of indication and the measuring converter.
• On the liquid crystal display of a thermohygrometer the current values of temperature and relative humidity of air are constantly highlighted. The period of updating of indications - 1 minute. When pressing any button the thermohygrometer passes into the "fast" mode of measurements and the period of updating of indications of the indicator decreases to 2 pages. Through 30 about the period of updating of indications of the indicator 1 minute comes back to value.
• The thermohygrometer remembers the minimum and maximum values of humidity and temperature, time and date of these events.
• Time of continuous work from one set of batteries (2 AA elements) - more than 2 years.
• The thermohygrometer can fasten on a wall by means of a plastic arm.
• If necessary the protective cap from a porous ftoroplast for protection against aerosols, dust and condensate is delivered.

The thermohygrometer of IVA-6N is issued in three modifications:

- without the built-in memory

- with the built-in memory

- with a memory card.
