POWDER FLOW MEASUREMENT WITH A RHEOMETER The Anton Paar Powder Cell, for the MCR rheometer series, brings an array of traditional rheological methods to the field of powder. The product makes it possible to simulate and determine powder flow under different conditions. An MCR rheometer plus a Powder Cell is a suitable combination for true rheological investigations of powders in quality control as well as research and development. The product combination can simulate and determine powder flow under different conditions; it therefore ensures efficient quality control and smooth powder processing. It can furthermore determine a powder’s cohesion strength — the internal resistance of the powder to flow — making it possible to predict whether a powder will flow through a process smoothly and whether the quality of a powder has changed. The device delivers reproducible results by clearing the ‘powder memory’ with fluidisation. An automatic measurement program ensures results within 2 min and therefore high throughput. The product is easy to use, providing automatically performed calibration and live visualisation of the measurements. Operating costs are said to be low and the dust protection hood safeguards the operator and the instrument from fine and potentially hazardous powder. More than just an instrument for quality control, the product also enables the study of dry granular flows, especially in the fluidised or near-fluidised state. It brings the precision achieved with MCR rheometers to the field of granular media. It not only includes a high-precision pressure-drop device, but also enables rotational and oscillatory tests in any state of consolidation, fluidisation or any state in between. The included precision mass flow controller gathers new data between zero-load and the fluidised state. MEP Instruments Pty Ltd www.mep.net.au

PORTABLE COLORIMETRIC CHLORINE TEST KIT The Electro-Chemical Devices HCA1 Portable Colorimetric Chlorine Test Kit is suitable for testing free and total chlorine in drinking water, wastewater, environmental waters, cooling towers and rinse waters in the food and beverage industry. The test kit is designed to use the Micro Strip reagent delivery system. The kit is supplied with 100 test strips for free chlorine and 100 test strips for total chlorine. Test strips for combined chlorine, chlorine dioxide, high-range chlorine and peracetic acid are also available for the HCA1 Chlorine Plus meter. The DPD test system used in the test kit is accepted by most health departments because the test is USEPA (DIN Standard 38 408 G4, ISO 7393/2) accepted for testing requirements for free and total chlorine. All tests have been calibrated using certified reference standards and standard analytical spectrophotometric methods. The algorithm in the kit’s software mirrors the AWWA, US EPA, DIN and ISO reference test methods for chlorine. The HCA1 Chlorine Plus System, with the Micro Strip CL (DPD-1), is said to repeatedly agree with an EPA Compliant reference method greater than 99%. The HCA1 Chlorine Plus Advanced Photometric System has been factory calibrated; the fixed calibrations in the meter will be valid for the life
