A100 AND A100H PORTON™ ANEMOMETERS
The Porton™ Anemometer is a highly sensitive but robust transducer in which the rotational speed of a 3-cup rotor is measured by means of a photo-electronic pulse generator and ratemeter. An
analogue d.c. voltage output is obtained which is substantially linear with respect to windspeed allowing accurate averaging of windspeed data.
The standard range A100 instrument gives 0..10v for 0..100Knots, the high range A100H instrument gives 0..7.5v for 0..75m/s. For low windspeed use, variants are available giving increased output voltages.
All rotors are supplied with individual calibration data traceable to national standards, and the low torque offered by the precision ball-race mounted shaft ensures a low thresholdspeed (0.15m/s) and good repeatability.
The small size and light weight of the A100 series anemometers together with the unique gravity sensitive fastener for the rotor facilitates use in portable applications.
These instruments also feature a remote calibration system.
Construction is from anodised aluminium alloys, stainless steels and weather resisting plastics for exposed parts. Precision corrosion resistant ball-races and a stainless steel shaft enable the R30 rotor response to produce a highly sensitive yet robust instrument suitable for continuous exposure to the weather.

AUTOMATIC DILUTION EXTRACTIVE - OPSIS POWERMAN 400
OPSIS PowerMan 400
Schematic showing OPSIS PowerMan 400 CEM systemThe OPSIS PowerMan 400 System is an automatic dilution extractive system, designed for continuous emissions monitoring of such
gases as NOx SO2 CO O2 H2O CO2 and Hg, all in one system.
The dilution sampling system extracts a small sample of gas from the stack. After particles have been removed, the sample is precisely diluted with clean, dry zero air. The sample is then transported to the analyser cabinet in a heat traced sample line.
The PowerMan 400 system complies with the EC large combustion plant directive and meets the requirements of the US EPA with regard to 40 CFR part 60/75.
The system is ideally suited for installations with long distances between analyser and measuring point, The system can be ordered with the OPSIS data management software, EnviMan which offers advanced data collection, validation, alarm reporting and statistical analyses capabilities as well as meeting EC and U.S. EPA reporting requirements.
The PowerMan 400 turn-key system is especially designed for combustion plants and the system is easy to install and maintain. The basic system includes probe, cabinet, data logger and NO/NOx measurement and the system can be easily upgraded to include analysers and sensors for the measurement of SO2 CO O2 H2O CO2 and Hg. Other options include an automatic calibration system and longer sample lines.

Finally, a portable Dew Point hygrometer that integrates the accuracy and reliability of chilled mirror technology, with the battery life and ruggedness required for field use.
Introducing the Model CMH-P portable chilled mirror hygrometer. This device incorporates all of the standard chilled mirror features that you've become accustomed to, such as drift-free NIST/NPL traceable accuracy, low maintenance, high durability and ease of use, in a system that is ideally suited for the demands of field use. Whether you use the Model CMH-P as a field transfer standard, or as a spot check instrument, you'll find this system trouble-free to operate.
The Model CMH-P is a self contained system; not only is there no field assembly required, there's no need to carry around a myriad of individual components such as control boxes, sensors, cables, pumps, and power cords. Simply attach the sample line, adjust the flow (with the integral flow meter) and turn on the power. Within minutes you'll be collecting field dew point data with the same chilled mirror accuracy of a laboratory standard hygrometer. And with a nominal battery life of 12 hours, you will be able to collect data for the entire shift, or spot check your processes for several days.
If you are looking for accurate, flexible, easy to use portable chilled mirror dew point measurement. Or, if you are tired of carrying around additional equipment, to make your process dew point monitor portable, contact Alpha Moisture Systems.

A & B SERIES NITRIC OXIDE SENSORS
The Alphasense Electrochemical range of Nitric Oxide sensors are available in both the companies 'A' and 'B' series sizes and are colour coded in light blue moulded tops. The NO sensors supplement
the already established Toxic Gas Sensor ranges that include Carbon Monixide, Hydrogen Sulfide, Sulfur Dioxide and Chlorine. The 'A' series is also available as an oxygen sensor.
The alphasense NO-A/B provides OEM's with a good, reliable sensor for use in a number of high volume applications. Strong signal levels combined with low zero current allows resolution to 200ppb (parts per billion) whilst giving linear outputs to as high as 250ppm (parts per million). The sensors are suitable for inclusion in fixed installation sensing heads, portable safety instruments and stack gas analysers.
The sensors incorporate innovative catalyst technology, which reduces the effects of a number of common cross interference gases whilst ensuring batch-to-batch consistency and stable output. These sensors provide a significant improvement in stability of response with respect transient relative humidity changes. These sensors allow OEM's to design instrumnts that provide trouble free monitoring of the reduced allowable maximum exposure limit of 1.0ppm for Nitric Oxide. Physical robustness allows the sensors to be used in the most demanding environments.
As with all other Alphasense sensors, the use of stabilisation racks to continuously monitor every sensor during initial conditioning ensures that only sensors operationg within specification are passed to the companies unique ATAV (Alphasense Test and Validation) system. The key operating characteristics for every sensor are recorded against the sensor serial number, which is bar coded onto the sensor. This data can be released at the time of despatch so that full traceability is maintained.

O2 & COE* (COMBUSTIBLES) ANALYSER COMTEC® 6000
Measuring principle of the Ga2O3-sensor for COe measurement
In general, a metal oxide sensor consists of an active layer, which resistance changes when exposed to the gas being measured. This
unique semiconductor gas sensor is operated at high temperatures approx. 750°C. Ga2O3 sensors show faster response and recovery times and lower cross sensitivity to humidity than other sensors. Additionally, Ga2O3 based sensors show stable long-term sensor properties even in flue gases containing of sulphur and dirt e.g. found in fuel oil burners. Furthermore, the sensor has an excellent performance and measurement repeatability.
The benefits of the Ga2O3 cell compared to other materials are the physical and electronic characteristics of the material. Compared to other commercially available metal oxide sensors, Ga2O3 sensors provide a series of unique product features:
• Ga2O3 sensors do not require any pre-aging or conditioning as some other metal oxide sensors. They are completely stable from “first use” and measure accurately within a few seconds from start up.
• Ga2O3 sensors show faster response and recovery times than other comparable sensors.
• They are almost insensitive to humidity changes.
• The selectivity and sensitivity can be controlled by the use of catalytic filter layers.
• Ga2O3 sensors have excellent manufacturing characteristics that produce consistent performance for the sensor resistance and operating sensitivity.
• Ga2O3 sensors are also stable in atmospheres with low O2 concentration (< 0.1 Vol %).
