Psychrometer Manufacturer,Supplier and Exporter in India
Product Code : EL-RAACL-10100
Jlab Export is a leading Psychrometer Manufacturer,and suppliers in India
Psychrometer (code EL-RAACL-10100) is a wet-and-dry-bulb instrument for finding the relative humidity of air; its red-liquid thermometers read -5 to 50 °C in 1° divisions. Recessed bulbs protect against breakage in use, and a water reservoir keeps the wick wet between readings. JLab makes this humidity instrument in Ambala, India, and packs it in a carrying case with a plastic chart.

How the Wet and Dry Readings Give Relative Humidity
One bulb is left bare and shows the air temperature, the dry-bulb reading. The other sits in the wick, and water evaporating from the wick cools it, so it settles at a lower wet-bulb reading. Drier air evaporates water faster and widens the gap between the two; in saturated air both read the same. Relative humidity is then found from a psychrometric table using the dry-bulb temperature and this difference, known as the wet-bulb depression.
Let the wet-bulb reading stop falling before noting it, and read both scales square-on to the nearest 1° mark. Keeping the reservoir filled with clean water stops the wick drying out during a series of readings.
Other Humidity and Air Velocity Instruments
- Digital Psychrometer — shows relative humidity with dry-bulb and wet-bulb temperatures, no chart needed.
- Hygrometer Wet and Dry — a wet-bulb and dry-bulb thermometer pair for measuring air humidity.
- Handheld Anemometer Digital — records air velocity, for example in front of an air conditioner vent.
