SYA-29S Constant-Temperature and Constant-Humidity Chamber for Testing Water Vapor Permeability of Rigid Foam Plastic Building Materials

Description

Product Introduction:

Product Features:

1. Built-in humidification, stable and precise.

2. Precise temperature control, uniform and stable.

3. Intelligent program, easy to operate.

4. The outer shell is made of electrostatically sprayed steel sheet, while the inner liner is stainless steel; the rounded corners facilitate easy cleaning and provide resistance to corrosion and aging.

5. It features a high-quality stainless steel inner liner with rounded corners, and the partition brackets can be freely installed and removed, making it easy to clean the working chamber.

6. Provision of test ports for convenient external sensor connection and monitoring.

7. Built-in water pump for automatic refilling. Equipped with an integrated humidification reservoir that uses a stainless steel heating element for heating.

8. The humidity sensor is an imported model, eliminating the hassle of frequent replacement of the wet‑bulb and dry‑bulb wicks.

9. Equipped with branded compressors and circulating fans, and featuring a unique air‑duct circulation design, this unit ensures uniform temperature and humidity throughout the chamber, while preventing sample volatilization and dry‑burning caused by excessive airflow during experiments.

10. Equipped with a self-diagnostic function.

11. Optional add-ons include a USB interface, printer, and other features.
