Psychometric MV-4-2M (MV4-2M; MV4 2M; MV 4 2M; MV42M; MV4 2M; MV-4 2M ; mv-4-2m; mv 4-2m; mv4-2m; mv 4 2m; mv42m ; mv4 2m; mv-4 2m)
Psychrometer MV-4-2M - mechanical suction device used to determine the relative humidity and temperature in the terrestrial environment.
- Relative Humidity - 10% - 100% (at a temperature of +5 ˚ C to +40 ˚ C);
- Air temperature - from up to -25 ˚ C +50 ˚ C.
Dimensions - Ø105 × 420mm.
Weight - no more than 1.2 kg.
Psychometric MV-4-2M can be used for measuring both indoor and outdoor seating.
Psychometric MV-4-2M works on the principle according to temperature differences, wet and dry bulb temperature of the ambient humidity. Mainspring mechanism and the device starts with a special key. Humidity is determined by special psychrometric tables (schedules) of the readings of dry and wet bulb thermometers. The air temperature is determined by the dry bulb temperature.
Specifications of MV-4-2M
Psychometric MV-4-2M in his work permit within ± 2% and ± 6% of the final reading.
Time unwind spring unit MV-4-2M should not be less than 6 minutes, while the fan aspirate at MV-4-2M at the 4th minute must be at least 2 m / s.
