JI-LLP Series Low Range Pneumatic Vacuum Cum Pressure Calibrator

Item

Low Range Pneumatic Vacuum Cum Pressure Calibrator 

Range 0.95 to 4 Bar 

Supplied along with Isolation Valve (Bench Top)

PRINCIPLE

It is a screw type pump used to Measure Low Pressure or Vacuum. It has got two main parts.

One Cylinder and A piston with Pushing Screw and Rotating Knob (4)

When we Rotate the Knob in the Clock wise Direction Pressure Increases and if was Rotate the

Knob in the Anti Clock wise Direction Minus Pressure / Vacuum Develops

PROCEDURE

To Generate Pressure Rotate The Knob in the Anti Clock Direction until

full Thread of the Piston Push Rod Appears Outside the Cylinder. Put the Master Instrument

at Position

(1) And put the Instrument To be Calibration at Position

(2) Using the Extension Cable Provided. Close the Release Valve
