Product Description
The Water Absorption Test Apparatus (gravimetric), also known as Vacuum Oven VO-281 is engineered to deliver precise and reliable performance for water absorption testing as per IS:10810 Part 33 or IS 7098. Its stainless steel inner chamber ensures durability and contamination-free operation, while the mild steel exterior with high-grade glass wool insulation maintains optimal temperature stability.
Equipped with a digital temperature controller-cum-indicator, the apparatus offers accurate monitoring and efficient heat management. The vacuum system includes a high-quality vacuum gauge and vacuum cock for convenient control during test procedures.
A robust oil-sealed vacuum pump ensures quiet, vibration-free, and continuous-duty operation. The pump assembly features an oil level sight gauge and drain plug for easy maintenance, while the motor-driven design ensures stable output. An air pump providing 7–12 LPM flow supports the chamber’s pressure requirements for standardized testing.
Ideal for electrical, material testing, and quality assessment labs, this apparatus delivers dependable performance, precise control, and long-lasting operational reliability.
