Monitor hydrogen peroxide in water-treatment applications

Electro-Chemical Devices

Electro-Chemical Devices

The advanced HP80 hydrogen peroxide analyzer (photo) measures hydrogen peroxide in terms of both parts per million (ppm) and the percent solution range to support a variety of process applications. It is easy to set up and use, right out of the box with no special tools, says the company, thanks to its plumb-and-play design. The analyzer system includes a hydrogen peroxide sensor, a pH sensor, a constant-head flow-control device (to maintain the optimum flowrate moving past the sensor during sampling), and transmitter with power supply, all mounted on a PVC wall panel. The HP80 analyzer features amperometric hydrogen peroxide sensors, which are manufactured with a gold cathode, silver anode and rugged microporous membrane. The operating temperature range for these sensors is 0 to 45°C (32 to 113°F). — Electro-Chemical Devices, Irvine, Calif.

Analytical transmitter helps to integrate multiple sensors

Endress+Hauser

Endress+Hauser

The Liquiline CM44P multichannel analyzer transmitter (photo) accepts up to 16 different parameters from six analytical sensors simultaneously, and transmits them via 4–20- mA HART, Profibus, Modbus or EtherNet/IP. It is designed to simplify the monitoring of processes, such as chromatography, fermentation, phase separation and filtration, all of which rely on multi-parameter monitoring. The CM44P accepts inputs from up to two process photometers and four analytical sensors simultaneously. Sensor types include pH, ORP, conductivity, dissolved oxygen, nitrate, turbidity, free chlorine and ion-selective sensors. Mathematical functions allow the device to calculate measured values on the basis of multiple input values, says the company. The CM44P also performs a variety of diagnostic assessments on all connected sensors and analyzers, reporting all resulting diagnostic messages according to NE107 categories, and an optional web server allows operators to remotely access the device. — Endress+Hauser, Greenwood, Ind.

A turnkey option for measuring chlorine dioxide

GF Piping Systems

GF Piping Systems

The latest addition to this company’s line of measurement and control products for disinfectant monitoring is the reagent-free Signet 4632 Chlorine Dioxide Analyzer System (photo). The system features amperometric sensing technology, a clear flow cell, flow regulator, sensors, filter and variable-area flow indicator in one compact unit. It measures chlorine dioxide levels up to 2 ppm in a variety of water-treatment applications, such as cooling towers, wastewater odor-control systems, food and beverage processing and more. The unique flow-cell design acts as a built-in flow regulator, automatically controlling the flow stream vertically across the sensor membrane, improving accuracy and allowing for inlet pressures from 15 to 120 psi (1 to 8 bars). — GF Piping Systems, Irvine, Calif.

Laser analyzer is highly selective and interference-free

ABB Measurement & Analytics

ABB Measurement & Analytics

The LGR-ICOS Model 950 (photo) is an online, continuous laser-based process analyzer that performs ultra-sensitive measurements of industrial trace gases, in applications including calibration, management of industrial gas blankets, tank and pipeline operations and more. It uses patented Off-Axis integrated cavity output spectroscopy (OA-ICOS) technology — a cavity-enhancement absorption technique that extends optical path lengths by multiple miles to greatly improve the sensitivity to such trace gases as CH 4, CO 2, CO, O 2, H 2 S, HCl, NH 3, HF, C 2 H 2, and others, says the company. The device is said to be easy to use, it requires no field calibration, and has minimal preventive maintenance requirements, and continuous diagnostics and warnings help to avoid emergency repairs. — ABB Measurement & Analytics, San Jose, Calif.

Combustion analyzer supports analysis and troubleshooting

The new EMIA-Expert carbon/sulfur analyzer is an advanced configuration model to the company’s EMIA-Pro (the basic model). Both offer non-dispersive infrared (NDIR) measurement capabilities, and are equipped with a unique CO detector. They can be used for a variety of inorganic materials, such as steel, coke, catalysts, non-ferrous metals such as aluminum, and lithium-ion battery materials. New functionality on the EMIA-Expert includes a high-performance purifier unit for carrier gas for high-accuracy measurement of ultra-low-carbon concentrations. High-performance heating-unit filters prevent absorption of SO 2 by moisture created by the samples during analysis. The patent-pending cleaning mechanism on both the EMIA-Pro and EMIA-Expert clears dust in the furnace, enabling up to 200 measurements without maintenance cleaning. This increased efficiency means one measurement cycle can be completed in about 70 s, or 50 samples per hour. — Horiba Scientific, Edison, N.J.

Inline viscometer monitors the rheology of drilling fluids

Ametek Brookfield

Ametek Brookfield

To optimize fracturing and drilling operations, the drilling fluid’s viscosity and rheology must remain be optimized. During hydraulic fracturing, the Brookfield TT-100 Inline Viscometer (photo) provides realtime, inline measurements for gels moving in pressurized lines from the hydration unit before being pumped downhole. The device continuously verifies that the fracturing fluid rheology at the well site is within established specifications and provides an alarm indication when it is not. — Ametek Brookfield, Middleboro, Mass.

Hybrid laser device provides continuous gas analysis

The Rosemount CT5100 continuous gas analyzer is the world’s only hybrid analyzer to combine tunable diode laser (TDL) and quantum cascade laser (QCL) measurement technologies for process gas analysis and emissions monitoring, according to the manufacturer. The CT5100 is ideally suited for process gas analysis, continuous emissions monitoring, and ammonia slip applications, which can detect down to sub-ppm levels for a range of components, while simplifying operation and significantly reducing costs. It can measure up to 12 critical component gases and potential pollutants simultaneously within a single system. The CT5100 has a simplified sampling system that does not require gas conditioning to remove moisture. — Emerson Process, Gothenburg, Sweden

This analyzer provides vapor pressure testing on the go

Ametek Grabner

Ametek Grabner

The MiniVap VP Vision is a portable analyzer and vapor-pressure tester that is designed to measure gasoline, jet fuel, crude oil, liquefied petroleum gas (LPG) and solvents, without the need to attach it to a pressure regulator. The analyzer is certified to work in cold as well as hot and damp climates, and withstands vibration and heavy shocks from any direction, says the company. These attributes make it suitable for use in mobile laboratories and demanding industrial settings. It comes with an extended pressure range of 0–2,000 kPa without compromising precision, according to the manufacturer, and its newly developed 2D-Calibration Correction Field (273 points) and exact piston-positioning (in the sampling valve) ensure accurate results and repeatability over the full measuring range. — Ametek Grabner Instruments, Vienna, Austria
