Sling Psychrometer Manufacturer,Supplier and Exporter in India

Product Code : SCL-PLE-11700

The Sling Psychrometer by Scientifc Equipment is an educational weather and environmental science instrument designed for measuring dry-bulb temperature, wet-bulb temperature, relative humidity, and atmospheric moisture conditions. It is ideal for school science laboratories, geography classrooms, environmental science lessons, weather study programs, field activities, STEM projects, teacher demonstrations, and student practical work.

This instrument helps students understand how humidity is measured using evaporation and temperature difference. By comparing the readings of a dry thermometer and a wet thermometer, learners can estimate relative humidity using a psychrometric chart or humidity table.

Product Description

A Sling Psychrometer consists of two thermometers mounted on a rotating frame or handle. One thermometer measures normal air temperature, known as the dry-bulb temperature, while the other has a wetted wick around the bulb and measures the wet-bulb temperature. When the instrument is swung through the air, water evaporates from the wet wick, cooling the wet-bulb thermometer.

The difference between dry-bulb and wet-bulb readings is used to calculate relative humidity. The Scientifc Equipment Sling Psychrometer is designed for supervised educational use and supports practical learning in meteorology, geography, environmental studies, climate science, evaporation, humidity, and weather observation.

How to Use

1. Check that both thermometers are clean, readable, and properly fixed in the psychrometer frame.
2. Moisten the wick around the wet-bulb thermometer using clean water as instructed by the teacher.
3. Make sure the dry-bulb thermometer remains dry.
4. Hold the handle securely and stand in an open, safe area away from other people and objects.
5. Swing the psychrometer gently through the air for the recommended time or until readings become stable.
6. Stop swinging carefully and immediately read the dry-bulb and wet-bulb temperatures.
7. Record both readings in a weather observation sheet or practical notebook.
8. Find the difference between the dry-bulb and wet-bulb readings.
9. Use a humidity table or psychrometric chart to estimate relative humidity.
10. Repeat readings at different times or locations to compare humidity conditions.
11. After use, dry the instrument if required and store it safely in a clean, dry place.

Safety and Handling Instructions

• Use only under teacher, laboratory instructor, or trained adult supervision.
• Swing the instrument only in an open area with enough space around the user.
• Do not swing the psychrometer near other students, walls, glassware, electrical equipment, or sharp objects.
• Handle thermometers carefully to avoid breakage or injury.
• Do not use broken, cracked, loose, or leaking thermometers.
• If a thermometer breaks, inform the teacher immediately and follow laboratory cleanup rules.
• Do not use the instrument during storms, lightning, heavy rain, or unsafe outdoor conditions.
• Keep the instrument away from excessive heat, chemicals, rough handling, and strong impact.
• Store the psychrometer safely after use to protect the thermometers and wick.

Educational Applications

• Measurement of dry-bulb and wet-bulb temperatures.
• Calculation of relative humidity using a psychrometric chart or humidity table.
• Weather observation activities in geography and environmental science classes.
• Demonstration of evaporation and cooling effect.
• Climate study, atmospheric moisture study, and field data collection.
• STEM projects involving weather instruments, humidity comparison, and graph preparation.
• Useful for school weather stations, practical examinations, science fairs, and outdoor learning.

Why Choose Scientifc Equipment Sling Psychrometer?

The Scientifc Equipment Sling Psychrometer is designed to make humidity measurement practical, visual, and easy to understand.

FAQ

1. What is a Sling Psychrometer used for?

A Sling Psychrometer is used for measuring dry-bulb temperature, wet-bulb temperature, and estimating relative humidity during weather and environmental science activities.

2. Is this Sling Psychrometer suitable for school laboratories?

Yes, it is suitable for school science labs, geography classrooms, environmental science lessons, weather study programs, STEM projects, and teacher-led demonstrations.

3. How does a Sling Psychrometer work?

It works by comparing the temperature of a dry thermometer with a wet thermometer. Evaporation from the wet wick cools the wet-bulb thermometer, and the temperature difference is used to estimate relative humidity.

4. What is the difference between dry-bulb and wet-bulb temperature?

Dry-bulb temperature is the normal air temperature. Wet-bulb temperature is measured by a thermometer covered with a moist wick and is usually lower because of evaporative cooling.

5. How is relative humidity calculated?

Relative humidity is estimated by using the dry-bulb temperature, wet-bulb temperature, and their difference with a psychrometric chart or humidity table.

6. Can students use the Sling Psychrometer outdoors?

Yes, students can use it outdoors under teacher supervision in safe weather conditions and open spaces suitable for swinging the instrument.

7. Can this instrument provide professional weather station accuracy?

This sling psychrometer is designed for educational weather observation and classroom demonstration. It is not intended for professional meteorological, industrial, medical, or critical environmental monitoring unless specifically approved.

8. How should the Sling Psychrometer be stored?

After use, dry the instrument if required, protect the thermometers and wick, and store it in a clean, dry, and safe place away from heat, moisture, chemicals, and impact.
