Abandoned mine water levels being monitored

altThe Environment Agency of England and Wales (EA) is monitoring water levels at an abandoned mine near Baldhu, Cornwall amid fears that overflow from the site could impact groundwater supplies in the area.

Site operator Veolia has alerted the EA to the issue at the Wheal Jane mine, with water levels continuing to rise in the main mineshaft. This poses the risk of water contamination from the structure into the nearby Carnon River and Fal Estuary.


New Compact Turbimeter for Reliable Turbidity Measurement

altPalintest Ltd (UK), specialists in water analysis technology, is delighted to announce the launch of the new Compact Turbimeter featuring QuadoptiX advanced testing technology.

Designed for the field professional to test turbidity in drinking water, wastewater and surface water, the Compact Turbimeter is built around the new QuadoptiX optical bench. This new technology effectively uses two independent turbidity measurement systems for dual validation, resulting in improved reliability and accuracy – especially for samples with mobile or settling matter.


New Tadpole GPRS Data Logger Launched

altWith the costs of mobile communications falling and the costs of site visits rising, now is the time to switch from data loggers to wireless telemetry for routine data collection.

Isodaq Technology (UK) has launched Tadpole, which sets new standards for ease of deployment in tight spaces and harsh environments. Tadpole is a fully-fledged GPRS RTU outstation water-proofed to IP68 standards with the main board sealed for life, but with SIM cards and batteries field exchangeable, making Tadpole ideal for rapid deployment on short-term surveys.


Modbus Humidity and Temperature Transmitter

altThe EE160 HVAC transmitter with Modbus RTU output is the ideal solution for cost-effective installation in a bus system. The precision of E+E's advanced sensor technology is combined with the latest manufacturing techniques to create a product with an outstanding price/performance ratio.

The E+E HCT01 humidity and temperature sensor used in the EE160 features outstanding protection against pollution which leads to excellent long term stability and to accuracy of ±2.5% across the entire working range.


New Early Flood Warning Systems

altFlooding, both predicted and sudden, has become an increasingly common phenomenon in recent years. Many suffering localities have been un- or under-prepared, with little reason to believe they were at risk until it was too late. A reliable and cost-effective advance warning system that continuously monitors rivers, storm drains and overflows for rising water levels can save lives and protect property, alerting authorities and communities to impending danger.

The SonicSens 2 battery-powered ultrasonic level and flow sensor, from specialist manufacturer HWM (UK), offers non-contact, accurate, remote and wireless monitoring of water levels and flow rates. The ultrasonic sensor precisely measures the distance to (and therefore level of) the water surface, and can automatically send alerts to up to 16 phone numbers when the level reaches specified thresholds. When an alarm condition activates, it can also provide accelerated dial-in functionality, allowing users to quickly access detailed, relevant and timely new information when they have to.


Noise pollution has increased due to the 'wrong kind of wind'

altNoise pollution complaints have risen more than 900 per cent in South West London, as the level of noise from Heathrow Airport has increased exponentially.

Although it was first believed that the increase in noise was down to both runways running simultaneously, it is now believed that a change in weather has caused the amplification of noise.

Some have reported that the noise is being carried over South West London when it was not previously.


Get Consistent and Accurate Results

alta1-cbiss (UK) are the UK’s distributor of the GASTEC gas detector tube systems. The GASTEC tube sampling system is designed to work in a multitude of applications offering a low cost and quick method of gas detection.

The GASTEC pump offers a sleek ergonomic design and has the ability to detect up to 600 gases, vapours and particulates.

The unique colorimetric tube technology displays results in a short time without requiring lab analysis making them the perfect gas detection method for sampling on remote sites and sites that need instant results.


Safe Determination of Halogens, Phosphorus & Sulphur

altThe Model OFCU-1 from Exeter Analytical (UK) provides a highly safe tool for preparing samples for elemental analysis of Halogens, Phosphorus and Sulphur using the Oxygen Flask Combustion procedure.

The oxygen flask combustion procedure is provided as the preparatory step in the determination of bromine, chlorine, fluorine, iodine, phosphorus and sulphur in some Pharmacopeial articles. Combustion of the material under test (usually organic) yields water-soluble inorganic products, which may be analysed for specific elements as directed in the individual Pharmacopeia monograph or general chapter. The oxygen flask combustion procedure using the attractively priced OFCU-1 is capable of being used for repeatable determination of elemental composition from percentage levels to parts per million.


Sierra Announces New Thermal Dispersion Technology

altSierra 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.
