Crowcon detector UL certified

Crowcon’s intrinsically safe TXgard-IS+ gas detector is fitted with electrochemical sensors which enable it to detect a range of toxic gases and oxygen. Gases detected include carbon monoxide, hydrogen sulphide, chlorine, ammonia, nitrogen dioxide, sulphur dioxide and oxygen. Already certified to ATEX and IECEx

PerkinElmer advances elemental analysis

PerkinElmer has launched the NexION 300 inductively coupled plasma-mass spectrometer (ICP-MS) for elemental analysis in Europe. “The NexION 300 platform

standards, the addition of UL certification means the TXgard IS+ can now be used globally, including North America, the Middle East and South East Asia in Zone 0, 1 or 2 or Division 1 or 2 hazardous areas when used with a safety barrier. Typical environments where the Txgard IS+ can be used include chemical and semiconductor manufacturing plants and water and sewage treatment plants.

Toxic gases: the TXgard-IS+

advances trace element analysis, and its introduction is perfectly timed to help address global problems ranging from contamination of our air, water and food to the integrity of pharmaceuticals and nutritional supplements, and the safety of emerging nanomaterials,” explained Martin Long, vice president, spectroscopy, PerkinElmer. The NexION 300 features patented Universal Cell Technology and is the only instrument of its kind with three modes of interference removal – standard, collision and reaction.

Dwr Cymru deploys ABB colorimetry range

Dwr Cymru Welsh Water has become one of the first utilities to upgrade its water treatment monitoring systems to ABB’s new range. The Aztec 600 colorimetric range combines Aztec’s patented ‘wet technology’ with the advanced electronic platform of ABB’s ScreenMaster data recorders. Welsh Water has already installed the new

systems at nine treatment works, where it is monitoring aluminium and iron using the 600 series, and phosphate, manganese and nitrate levels using Aztec 1000 units. The contract included instrumentation for conductivity and pH measurement. The Aztec 600 range provides powerful and reliable on-line colorimetric analysis of the main water treatment parameters.

Netherlocks system proves reliable

A failure modes, effects, and diagnostic analysis (FMEDA) report, carried out by Exida, has shown that the Netherlocks partial-stoke system, Fail Action Integrity Test Handling (FAITH) is very reliable. For most cases, the FAITH is suitable for use in SIL3 applications. The FAITH system makes it possible to carry out a manually initiated partial stroke test on emergency shutdown (ESD) valves during normal operation, without interrupting process flow. With mechanical stops it limits the angle of the stroke of the valve-actuator combination to a set percentage – ensuring the ESD valve ‘works’, without shutting down the operation.

Leak detection from your desktop

The PermaNet system from HWM Water transmits leak data collected from Permalog loggers directly to an office computer wirelessly, via network radio or SMS repeater. Permalog technology has been proven in some of the harshest conditions. Easily installed on pipe fittings, the loggers listen for the noise made by water leaking from pipes and, when a potential leak is detected, they enter an alarm state and transmit a radio signal. Loggers can be quickly deployed and used repeatedly with

no disruption to the surrounding area or to the water supply, and the precise location of each logger can be recorded on detailed GPS mapping software as it is put into the ground.

On-line COD monitor saves on all fronts

An on-line monitor that enables accurate, sensitive, real-time analysis of chemical oxygen demand (COD) is now available from Camlab. The PeCOD analyser can generate a reading every 15 minutes, providing unrivalled analysis data of waste or discharge streams. On-line, real-time monitoring of processes enables them to be adjusted to reduce energy use, making downstream treatment more cost effective and preventing waste of expensive ingredients. After testing of the laboratory model in real-life applications

Accurate analysis: the PeCOD

over the past 18 months, Camlab is now supplying the on-line monitor version to UK food and beverage manufacturers.
