Sherwood Scientific has enhanced its Model 926 chloride analyser, which is suitable for manufacturing, food analysis and clinical applications.
The new analyser features a redesigned printed circuit board (PCB), a sealed faceplate and a backlit LCD display.
The Model 926 is described as an accurate and precise instrument for measuring salt in food products.
The latest version of the instrument offers the familiar mode of operation and the same results format.
Changes to the PCB have facilitated the incorporation of surface-mount switches protected by a leak-proof membrane, making for a more rugged instrument and simplifying cleaning, according to the company.
The new 2.75in 60dpi LCD display provides additional on-screen status information, units of measurement and operator prompts.
Food manufacturers require a method of rapidly and accurately checking chloride (NaCl) concentration in foodstuffs such as snacks, cheese and seasonings for QA/QC purposes.
Chloride content is also a critical measurement in cement manufacture and, as in the food industry, Sherwood's Model 926 chloride analyser can deliver accurate results without the need to make up the fresh reagents required by traditional silver nitrate methods for chloride determination.
For food industry applications, a dedicated button on the 926 provides an instant conversion of the measured mg/litre chloride into a mg percentage salt content in the foodstuff under analysis.
The Model 926S is designed specifically for clinical use, principally the determination of chloride in sweat samples, an elevated level being indicative of the condition cystic fibrosis.
The option to handle volumes as small as 20ul without the need to recalibrate the unit is a particular advantage in this analysis, given that the test is usually applied to tiny samples from babies and infants.
Other features new to the Model 926 analysers include two USB sockets, enabling firmware revision uploads and data download to a computer, complementing the original RS232 port, which is retained.
The new Model 926 is supplied with a universal power supply and a plug adaptor kit suitable for worldwide use, while an external transformer ensures cooler operation and enhanced surge protection.
Finally, factory-set calibrations ensure accuracy over a wide range of measurement, according to the company.
