Sierra Instruments today introduces their new QuadraTherm™ 640i / 780i Thermal Mass Flow Meter Series, marking a disruptive breakthrough in thermal dispersion technology. With its sensor design advancements, coupled with a proprietary iTherm “Brain”, the 780i inline version achieves gas mass flow rate measurement accuracy of +/- 0.5% of reading above 50% of the full scale (Air) making it the most accurate thermal meter in the industry. Before today, this level of accuracy was never thought possible with thermal dispersion mass flow meters.

At the heart of the 640i / 780i is its revolutionary patented QuadraTherm sensor and proprietary iTherm™ algorithm set. Traditional thermal sensors have two sensors–one temperature sensor and one velocity sensor, each in a separate probe. QuadraTherm introduces four sensors—three precision platinum temperature sensors and one patented no-drift DrySense™ mass velocity sensor, which is backed by a lifetime warranty and uses a proprietary manufacturing process to greatly improve accuracy and long-term stability.

FOSS NIRSystems, Inc. (USA) have introduced Vision 3.60. Vision is a software package specifically designed for use with the FOSS NIRSystems Near-Infrared (NIR) laboratory and process analysers. Vision 3.60 replaces earlier versions of Vision and offers support for the latest NIR laboratory and process hardware.

The main new features in Vision 3.60: Vision 3.60 is 64 bit compatible. Vision can now be installed and run on both 32 bit and 64 bit versions of Windows XP, Windows Vista, and Windows 7. Vision 3.60 supports the NIRS DS2500 Analyser

Teledyne Leeman Labs (USA) Hydra IIC Mercury Analyser eliminates the complicated chemistry and hazardous waste associated with conventional mercury techniques. The Hydra IIC is a fully automated turnkey analyser that measures mercury in solid and semi-solid sample matrices directly without any acid digestion (sample preparation).

The system employs the technique of sample combustion (thermal decomposition), mercury concentration via gold amalgamation and detection by cold vapour atomic absorption. The biggest advantage of the Hydra IIC is that no sample preparation is required before analysis.

To efficiently compost waste, continuous temperature readings are required from the compost heap or windrow.

Manual data collection and risk of contamination are eliminated using a SureCross Node from Banner Engineering (Belgium), equipped with a dedicated thermocouple probe to automatically monitor the compost temperature.
