New Ammonia and Nitrate Analyser for Water and Wastewater
Timberline Instrument’s (USA) TL-2800 Analyser provides a rapid, low maintenance method to measure ammonia and nitrate in water and wastewater samples. Recently recommended for wastewater determination by the USEPA (ATP Case # N08- 0004), the TL-2800 uses a continuous flow gas diffusion and conductivity detector to measure ammonia in aqueous solutions.
Common applications include surface water, watershed, chloraminated drinking water, and wastewater influent and effluent. Results are unaffected by turbidity, colour, or particulate matter. Ultra-sensitive detection down to the ppb level is easily achieved. The robust system introduces sample via peristaltic pump, which reduces the need for filtration and prevents costly repairs and maintenance issues associated with sample injection valves.
The integrated data acquisition hardware runs with Microsoft Windows 7 operating system for easy connection to networks, printers, or external USB drives. The intuitive software provides compete automation of the instrument and sampling system with a graphical user interface that is easy to learn and implement.

New Silica Analyser Launched Swan Analytical (Switzerland) are pleased to announce the release of the newly developed AMI Silica.
The Silica analyser is now fitted with the new Periclip pump and 2 Litre reagent canisters, for the ease of maintenance and uses the well proven continuous flow photometry.
The analyser is intended for Silica measurement mainly in water steam cycles, cooling- and surface water. The AMI Silica offers a meauring range of 1 to 5’000ppb
The analyser can be equipped with an optional 2nd sample stream switching valve or connected to the AMI Sample Sequencer for up to 6 sample streams.

The Merck Millipore (Germany) Spectroquant®
mobile, robust instruments for reliable water analysis. They are simple to operate and pre-programmed for use with Spectroquant®
test kits.
Now two new reference standard kits for verifying the accuracy of the Picco and Multy instruments are available. Both kits include sealed cuvettes containing coloured test solutions and a blank, quality documentation and an instruction manual all packed in a handy carrying case.
The reference standards have been validated as specified in the accompanying quality certificate. They provide
Wireless Solutions for Landfi ll
Leachate removal from a landfill is an important operational process. Using a SureCross Wireless Network, pump counts can be collected to ensure leachate levels are maintained automatically.
SureCross Nodes with totalizing counter inputs installed at each pump, calculate the removed total leachate volume, based on the total number of pump cycles
Manual data collection is eliminated with a Wireless network solution, all information is sent back to a central control location to save time and eliminate errors
SureCross Gateways offer a variety of serial protocol outputs to integrate with existing wired network infrastructure
Reference Standard for Chlorine, Chlorine Dioxide and Ozone; kit contains 3 sealed cells containing stable, colored solutions plus 1 sealed blank cell, quality certificate and user instructions. Suitable for use with the Spectroquant® Colorimeter Picco Cl2/O3/ClO2/CyA/pH and the Spectroquant®
you with reassurance that your results are both accurate and reliable. Spectroquant®
Colorimeter Multy. Spectroquant® Verification Standard for Spectroquant® Multy colorimeter; kit contains 6 sealed cells containing stable,
coloured solutions for measuring the absorbance at 430 nm, 530 nm, 560 nm, 580 nm, 610 nm, and 660 nm plus 1 sealed blank cell, quality certificate and user instructions. Suitable for use with the Spectroquant®

Precipitation Gauges Engineered for Year Round Measurements
The T-200B Series Precipitation Gauges are designed for year round measurements of accumulated precipitation (solid or liquid) as well as precipitation intensity. The amount of precipitation is measured by Geonor’s (Norway) unique vibrating-wire weighing transducer. Despite its simplicity, the gauge is very accurate and easy to install and maintain.
The gauge was designed to function in remote areas without heating; with proper power supply from batteries and solar panels electrical inlet heaters can be used to minimise "capping" of inlet.
The T-200B Series Precipitation Gauges were developed in 1985. Some of the gauges supplied at that time are still in use today and continuously monitoring for various meteorological agencies. They are used worldwide by weather services, transportation agencies, power companies, avalanche prediction services and agricultural agencies. In comparison tests with other gauges, National Center for Atmospheric Research (NCAR) the Climate Reference Network (CRN) and the World Meteorological Organisation/Commission for Instrument & Methods of Observation (WMO/CIMO) ranked the T-200 first.
There are no moving parts. The precipitation, oil and antifreeze in the container are weighed with a sensor giving a frequency output. The frequency will be a function of the tension applied to the vibrating wire; the frequency increases as tension on the wire increases due to increased precipitation collected. The measuring principle is well suited for remote locations requiring a reliable and long-lasting instrument.

The amount of precipitation can be measured at intervals ranging from seconds to weeks; this can be determined by the programming of the Data Logger in use.
