Product Description
There screens are manufactured as per IS:5948:1970 and are suitable for housing thermograph, hydrograph, dry and wet bulb, Thermometer and Maximum-Minimum Thermometer. Basically, these are manufactured from best quality Indian wood and accurately assembled with side louvers and supplied available in two sizes : Small size and Large size.
The interior size of the screen will depend on the number of instruments that are to be used. A single screen may measure 76.5 by 61 by 59.3 cm (30.1 by 24.0 by 23.3 in) and a double screen 76.5 by 105 by 59.3 cm (30.1 by 41.3 by 23.3 in). The unit is either supported by four metal or wooden legs or a wooden post.
The top of the screen was originally composed of two asbestos boards with an air space between them. These asbestos boards have generally been replaced by a laminate for health and safety reasons. The whole screen is painted with several coats of white to reflect sunlight radiation, and usually requires repainting every two years.

Robust Meteorological Shelter
The Stevenson Screen offers superior protection for meteorological instruments, shielding them from direct sunlight and precipitation. Its teak wood construction provides durability, while its standardized dimension accommodates essential devices for accurate climate monitoring. This makes it a reliable choice for both field and laboratory settings.
Advanced Data Logging Capability
Equipped with a portable data logger, the Stevenson Screen can record up to 160,000 measurements with a quick 1-minute standby time. The 16 GB memory capacity ensures long-term data collection, vital for researchers and meteorological departments aiming to study temperature and humidity trends over extended periods.
Efficient and Manual Operation
The screen operates manually and is battery-powered, featuring a user-friendly approach that simplifies maintenance. Its 2000 mAh battery capacity allows for sustained use without frequent charging, making it practical for remote field stations and areas with limited access to consistent power supply.
FAQs of Stevenson Screen:
Q: How does the Stevenson Screen help improve accuracy in temperature and humidity measurement?
A: The Stevenson Screen is specifically designed to shield meteorological instruments from direct sunlight, rain, and wind, ensuring that air temperature and humidity readings remain unaffected by external environmental variables. This setup yields highly accurate measurements, essential in meteorological and climate research.
Q: What types of devices can be housed inside the Stevenson Screen?
A: Typical instruments placed inside the Stevenson Screen include thermometers, hygrometers, and other air temperature or humidity sensors. It is equipped with a portable data logger and supports manual operation for standard meteorological applications.
Q: When should the Stevenson Screen be used during meteorological observations?
A: The Stevenson Screen should be deployed whenever precise and consistent air temperature or humidity data is required. It is particularly useful in weather stations, research sites, and agricultural fields where environmental monitoring occurs daily or at regular intervals.
Q: Where is the Stevenson Screen best installed for optimal performance?
A: For best results, the Stevenson Screen should be placed in an open area, away from buildings and trees to prevent any artificial influence on the measurements. The standard size and portability make it suitable for both permanent installations and temporary field setups.
Q: What is the process for collecting data using the Stevenson Screen?
A: To collect data, meteorological instruments are installed inside the shelter, which are then read manually or with the portable data logger. The logger stores up to 160,000 measurements, and the user can retrieve and analyze the recorded data using the provided user manual.
Q: What are the benefits of using a Stevenson Screen made from teak wood?
A: Teak wood offers excellent durability and resistance to weather conditions, ensuring the screen stands up to long-term exposure outdoors. This maintains the integrity of the shelter, providing consistent protection for sensitive instruments and reliable measurement over time.
