FIELDS OF APPLICATION
The drum-chart recorders are suitable for measurement of pressure or temperature whereas readings are recorded on graph paper by fibre pens
The operating time of the drum perrotation can be 30 min, 45 min or 90 min as well
as 24 h or 7 d. It is driven by mechanical spring winding or by battery supplied quartz controlled drive.
Drum-chart recorders are used for measuring and recording pressure, eg at leak tests of tubes and other pipings for gas and water.
The portable measuring instrument is particularly suitable for installation workings at building sites or when implementing gas or water connection in buildings
