Case
The Clearscan recorder case is made from high quality zinc coated steel, finished in epoxy powder paint that has a high resistance to weathering, scratches and industrial fumes. The window is high quality acrylic. The case has a lockable front-hinged door, permitting easy access to the chart and pens, and may be either wall, panel or pipe mounted.

Each recorder is supplied with a packet of 100 charts Chart Drive Motor The Clearscan Chart Recorder uses chart drive motors that are available as mains powered, mains powered with battery back-up, mechanical (spring-wound) and battery operated with a wide variety of chart speeds (24 hour and 7 day are standard).

Temperature Systems
The Clearscan chart recorder uses the proven and reliable Rototherm stainless steel thermal system. These consist of a bourdon tube, stainless steel capillary and a stainless steel bulb. All systems are filled with a non toxic filling temperature systems.

Pressure Systems
Proven and reliable pressure systems are used to record gauge pressure, vacuum, combined pressure and vacuum, absolute pressure and differential pressure.

Differential Pressure Systems
Differential pressure and flow can be recorded by using a differential pressure cell mounted to the rear of the instrument.
Minimum differential pressure range is 0 to 100” Wg. Wetted parts can be supplied in a variety of materials to suit a
broad range of process applications.
