Icon Scientific announces Pour Point analyser

January 18, 2016 - Icon Scientific announced Pour Point analyser that is used to provide an indicator of the lowest temperature at which typically a fuel oil may be used.

It provides accurate and repeatable measurement results, without the need for a chiller to cool the water.  Negating the need for chilled water reduces running costs and conquers the logistical limitations which have long governed where and how pour point analysers can be used, opening geographical frontiers such as deserts and other remote locations.

Designed to meet ASTM D97, D5853, D5949 and D5985 pour and no flow point analysis standards, Pour Point analyser is housed in a self-contained all explosion proof construction ATEX and IECEx certified unit, which requires no purge gas for operation.  

The low mass measuring cell traps a small amount of the sample in a “ U” tube. This is then cooled at a controlled rate by the Cryocooler. At pre-set temperature intervals the sample is pulsed at one end of the “U” tube by a cylinder equipped with a piston driven by a stepper motor. Sample movement is then detected by a differential pressure sensor connected to the ends of the “U” tube. The cooling is continued until the applied differential pressure pulse has been attenuated sufficiently to indicate that the sample is no longer moving. This temperature is taken as the pour point. The old sample is then warmed and flushed away and the cycle is repeated.

This cooling system enables Pour Point to offer variable cooling rates controlled via Icon’s 17” wipe clean, explosion proof glass graphical user interface (GUI) using user friendly software which is both easy to learn and configure. Extensive digital and analogue connectivity enables remote operation through easy system integration with options including standard Modbus RS485 wired output (fibre optic optional), LAN Ethernet connectivity, 4-20mA outputs and alarm contacts.
