Humidifier S.S Body DR 143
Humidifier S.S Body DR 143

HUMIDIFIER S. S. Body DR 143 Based on the ratating disc-splash plate principal. It produces only super fine particles of micron size, which become part of the atmosphere, thereby reaching every corner of the room, resulting in uniform humidity. Due to the upward thrust imparted to the micron sized water droplets, by high speed motorized unit, they remain suspended in the atmosphere for longer duration of time.he unit is capable of atomizing up to 3 litres of water in an hour at full evaporation, in the driest possible ambient conditions. The unit has body made up of S.S. A single unit is effective for an enclosed space of volume up to 40 cu. mtrs. The unit is provided with high speed 2800 RPM motor to run longer period, and the blades are aerodynamically balanced to ensure drop less fumigation. To work on 220/230 volts A.C. supply OPTIONAL ACCESSORIES a) Control box with humidistat b) Automatic 0-60 minutes ''GERMAN'' Timer

Rain Gauge
Rain Gauge

The most common rain gauge is the ordinary rain gauge, which simply consists of a collector place above a funnel that leads into measuring cylinder, where the rainwater is stored between observations. The measuring cylinder is specially graded to give the rainfall measurement in mm. Alternatively, where rainfall can be particularly heavy, a large container is used to collect the rainwater. Readings are made by pouring the rainwater out of the container into measuring cylinder so that the rainfall could be measured.
