Dewell integral plastic fixed or temporarily installed pressure gauges are available in inclined and vertical (well) types for measuring static pressure, vacuum, or differential pressure of air or gas. In order to ensure the required accuracy of this equipment, all holes are machined to the highest precision, which is a reflection of Devil's long-term experience in manufacturing organic glass construction tools.

● The thick organic glass body is a solid whole, which is basically unbreakable, stable, and will not deform.

● The drilling accuracy is ± 0.002 ●, which will never bend or deform and does not require recalibration.

● Carefully selected pressure gauge oil has high wetting ability, forming a consistent and beautiful meniscus, allowing for accurate readings.

● Adjustable reflective polished aluminum scale with adjustable knob lock for easy zeroing.

● Simply aligning the meniscus and its reflection image on the scale can achieve zero parallel error readings, which can achieve maximum accuracy and consistency.

● Equipped with a sensitive ground glass bubble level calibrator, the inclined pressure gauge has a spiral level adjustment function that can quickly and accurately provide a liquid level reference surface.

● Complete installation accessories and plastic portable case
