Measurement solution for soil chamber gas flux

by Protea Limited     based in Middlewich, UNITED KINGDOM

Closed chamber gas flux measurements can be made with Protea FTIR analysers to allow researchers in the field of atmospheric gas analysis from agricultural and livestock to measure evolved gases such as N2O, CO2, CO, NH3, and CH4. Nitrous oxide (N2O) and Methane (CH4) emissions from soil, plant and livestock are especially important gases to measure, given their high potential as greenhouse gases (GHGs). NH3, whilst not a greenhouse gas on the scale of N2O, CH4 and CO2, is a major emission from agricultural, such as after the spreading of liquid manure, and steps are required to measure and reduce the NH3 emissions and the effects they have on the ecosystem.

Noise monitoring solutions for vibration testing

by Brüel & Kjær Sound & Vibration Measurement A/S     based in Nærum, DENMARK

Vibration testing is is used for aerospace and defence testing, ground transportation, transport simulation, package testing, altitude simulation and more. Our comprehensive range of LDS electrodynamic shakers are designed for vibration testing of devices of any size - from a semiconductor component to a complete satellite system, to see how it will stand up to real-world conditions. With an LDS vibration test system your shaker, power amplifier, vibration controller and even environmental chamber are not only controlled from one PC, they run under one software package. Combined with data acquisition systems and analysis software suites, Brüel & Kjær ofers the complete vibration testing solution to establish proof of quality according to national and international standards, such as DIN, ISO, BS, MIL, IEC and ASTM.

Mercury monitoring for mercury flux measurement

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the inlet and outlet concentration over a selected surface to determine the flux over time. Alternatively, the micrometeorological gradient method uses measured concentrations at two levels above a surface. The perfect tool for both flux measurement methods is the Tekran 1110 Two Port Sampler, so the Tekran 2537 can automatically switch between two distinct sampling points. Ask us how we can help you setup a mercury flux system.

Gas control equipment for Life Science

by QCAL Messtechnik GmbH     based in Oberostendorf, GERMANY

QCAL introduces CO2Control for incubators and test chambers. These gas dosing units can be adapted to nearly every incubator or test chamber. The user can set a CO2 concentration up to 30% vol. CO2. The CO2Control measures the actual concentration and adds CO2 from a CO2 gas container. The NDIR CO2-sensor has an excellent long-term stability, which provides years of stable CO2 measurement. Also the other parts as the sample gas pump, valve and fittings are designed for maintenance-free use over years. Humidity effects are compensated upto 95% rh at 37°C, also temperature effects are automatically corrected upto 50°C. The other way to control gas atmospheres in any life science equipment is to use gas mixing units GMS_2CH ( 2 channels ) or GMS_3CH ( 3 channels ) for N2, O2 and CO2. They can match flowrates up to 80 liters per minute with a concentration range up to 100 Vol% O2 and/or CO2.
