viii UK Focus Low-Cost Outdoor Cable & Pipe Locator Introduced to UK
Aegis (UK) has introduced the CZ1891 TraceAll outdoor cable & pipe locator to the UK market. Designed to help avoid expensive utility repairs, the outdoor cable and pipe locator helps in locating and tracing services before digging begins. The kit consists
of the TraceAll base transmitter, light weight Tracing Wand and Inductive Coupler. It has the capacity to locate cables and pipes to a depth of 2 metres and can trace beyond a length of 2 kilometres. A coupling clamp can be supplied as an optional extra. Already something of an industry standard in its native Australian homeland, the cost of the CZ1891 means that ‘dig & pray’ can no longer be justified.

A new, cost-effective instrument that lowers the cost of entry to multiparameter clean and waste water testing has been introduced by Camlab, one of the UK’s leading scientific equipment suppliers.
The Camlab Water MC500 multiparameter colorimeter is designed to test more than 70 different clean and waste water testing parameters for the cost equivalent to two single parameter colorimeters.
The MC500’s design combines the mobility of a portable photometer with the characteristics of a modern laboratory photometer. The instrument addresses all the important parameters of water analysis, from aluminium to zinc. The high level of accuracy of Camlab water reagents and the userfriendliness of the MC500 enable rapid and reliable analysis of water samples for a variety of application markets including utilities, power, field measurement, aquaculture and industrial manufacturing.
Depending on the application, or the users’ requirements, this versatile instrument is capable of operating with powder pillows, tablets reagents or liquid reagents.
The easy-to-use MC500 features automatic wavelength selection and operates with six interference filters and uses longlife LEDs as a light-source. The MC500 has a memory capacity which is able to store up to 1000 data sets.
An optional infra-red interface for the MC500 enables data to be transmitted to a computer or printer (RS 232 / USB). For more information contact Camlab Ltd on 01954 233110 or visit the website at

AD Biogas Calorie Count for Government & Industry... Calculates Housed Livestock’s Potential to Supply 8% of Northern Ireland Electricity
UK government policy makers and the AD industry need independent benchmarked data for anaerobic digestion (AD). The Agri-Food and Biosciences Institute (AFBI), in Northern Ireland is benchmarking AD performance with different on-farm sourced feedstock such as manures and crops.
Energy from dairy cow slurry
The AFBI report indicates that during the first 18 months of operation, dairy cow slurry was used as the sole feed source and that the biogas produced had an average of 56 percent methane. It was found also at AFBI that, on average, one tonne of dairy cow slurry at 7.2 percent dry matter produced 15.5 cubic meters of biogas containing 86 kWh of energy. When expressed as biogas production from organic matter digested, it was found that one tonne of organic matter in slurry produced 280 cubic meters of biogas.
Biogas Analysis
As a research facility, AFBI Hillsborough needs to know biogas methane (CH4) concentration to determine its calorific value and the potential of each feedstock. ABFI uses an Automated Extraction Monitoring System (AEMS) unit from Geotech (UK) to analyse, measure and data log four gases; CH4, H2S, O2 and CO2 going to its CHP engine and biogas boiler. The AEMS unit monitors the gas before and after scrubbing in a column of activated carbon which brings the H2S down from a about 1800ppm to well under the 800ppm limit stipulated by the CHP manufacturer.
At AFBI the AEMS unit, which can measure at 10-second intervals, is set to analyse, measure and log AFBI data every 60 minutes giving 24 readings every day. With the first project to benchmark the performance of AD using dairy cow slurry as a sole feedstock complete, the next is to co-digest dairy cow slurry with grass silage.
Need to... your PIDs & gas detectors?
Ashtead Technology can now do it all!
As well as repairs, servicing and calibration to RAE Systems factory standards, we can also deliver a hire instrument prior to sending us yours.
Repair, Service & Calibrate
This is to see how agriculture can benefit from the huge potential opportunity of AD in Northern Ireland. Indeed, it is calculated that all of Northern Ireland’s total supply of manure from housed livestock has the potential to generate eight percent of all Northern Ireland’s electricity demand. Co-digestion increases that potential hugely.
Data logging and transfer
The data gathered by the AEMS system is transferred remotely for access by AFBI. Using a GPRS modem and SIM card, data is securely transferred to a remotely operated server, from where AFBI downloads the data, via a secure Internet connection and transfers it into exportable spreadsheet formats for processing and storage. This remote GPRS link also enables full diagnostic capability and also allows Geotech to remotely re-configure and maintain the system should this be necessary.
Zero Downtime
Under its Geotech service contract AFBI’s detachable gas analysis unit has been back to Geotech twice for factory service and calibration. It is ’hot swap’ exchangeable to ensure zero down time during routine service.
*Applies only to RAE Systems portable PIDs and gas detectors

The anaerobic digester at AFBI-Hillsborough was designed, supplied and constructed by Greenfinch Ltd (now BiogenGreenfinch), Ludlow, Shropshire. Construction took place between September 2007 and March 2008.
