Model LR-Cal 2941

Description

LR-Cal 2941 Description

The vacuum test pump LR-Cal 2941 is used to generate vacuum (negative pressure) for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements. These vacuum tests may be carried out in laboratories, workshop or on site at the measuring point.

If the instrument to be tested and a sufficiently accurate reference measuring instrument are connected up to the test pump, the same vacuum is applied to the two measuring instruments when the vacuum test pump LR-Cal 2941 is is operated. By comparing the two measure valuses at random pressure values, the accuracy can be verified or the instrument under test can be adjusted.

Despite its compact dimensions, the vacuum test pump LR-Cal 2941 is easy to operate and allows for exact generation of the required test vacuum. The  LR-Cal 2941 is fitted with a fine adjustment valve for precise adjustment of vacuum. Pressure connection is made with 4 mm hose, a T-piece wich quick-coupling and a piece of hose is included in standard delivery.

Standard scope of delivery:

• Vacuum test pump LR-Cal 2941 with hose connector for hose with 4 mm inner diameter and 6 mm outer diameter
• Test hose 0.3 m
• T-piece
• Manual

For a simultaneous connection of reference and test item, you need at least two further pieces of hose, see "Accessories".
