Differential micro-manometer BL569

analogtestlaboratory

The BL569 compensated micro manometer is a precision low pressure balance. It equipped a big movable reservoir and a small fixed reservoir. By moving up and down the big reservoir, the pressure generated by the water level difference between the big and small reservoir is balanced with the desired pressure from external pressure calibration pump. It is very easy to calibrate low pressure, vacuum and differential pressure in laboratory. FEATURES • Ranges ± 2500 Pa • Accuracy is up to ±0.4Pa • The transparent observation tube is equipped with a water gauge head, which can observe the level changes in big reservoir. • The reflective mirror can show the contact between the water level head and the liquid level inside the observation tube. • Fine adjust disc with 200 equal divides is fixed on a long screw. The long screw moves big reservoir up and down. The bottom scales shows the height of big reservoir. APPLICATION • Low pressure calibration and test in lab. • Low pressure test, vacuum test, differential pressure test (non corrosive gases)
