GASMET GT5000 TERRA

GT5000 Terra, the world’s smallest, portable (9.4 kg) and splash proof (IP54) multigas FTIR analyzer. Capable of measuring up to 50 gases simultaneously, with constant monitoring, online. Easy to use with low cost of ownership.

The GT5000 Terra's major advantage is that the sample cell remains at ambient temperature. This reduces preparation time prior to sampling and increases battery efficiency for the unit.

GASMET DX4015

Gasmet DX4015 is a portable FTIR gas analyzer for ambient air analysis. The key features of the Gasmet DX4015 include a high sensitivity sample cell for the lowest possible detection limits and a built-in-pump, which means that there is no need to use a separate sampling system. The analyzer can be powered with 12 VDC from for example an external battery, so it can easily be used in field conditions where mains power is not available.

The Gasmet DX4015 can measure up to 50 gases simultaneously, and the addition of new measurement parameters is easy, without any need for hardware changes. Gasmet DX4015’s sample cell is heated to 50 °C, which allows measurements to be done in conditions where high humidity is expected and provides temperature stability in changing conditions.

EARTHSENSE ZEPHYR AIR QUALITY SENSOR

The Zephyr is a compact and lightweight ambient air pollution sensor that accurately measures harmful gases and particle matter. 

With more focus being placed on budget-friendly air quality monitoring sensors to identify potential pollution hotspots, the Zephyr is possibly the best and most functional unit available in the South African market.

Its ability to measure NO, NO2, O3, CO, SO2, H2S, PM10, PM2.5 and PM1in additional to ambient temperature and relative humidity will make it the ideal tool for the South African air quality market.

EARTHSENSE EXPANDS ITS ZEPHYR PRODUCT OFFERING

EarthSense announced updates to its flagship product, the Zephyr air quality sensor that include TVOC and CO2 measurement capabilities, additional RS232/RS485 third-party connections and 4G/5G technologies, LTE-Cat M1 and NB-IoT.

Third-party RS232/RS485 connections open the door to connecting a wind speed / direction sensor to this already feature packed instrument.

The introduction of 4G and 5G technologies, LTE-Cat M1 and NB-IoT, takes the Zephyr to the cutting edge of communications technologies for small form air quality sensors. This allows for robust global deployment options for users as part of city-wide, low-power IoT initiatives. 

TELEDYNE API N500 CAPS TRUE NO2, NO, NOX ANALYSER

Teledyne API produces a wide range of instruments for the measurement of Nitrogen compounds, including those that measure 'True NO2'. Click here to view the full range of these instruments.

The Model N500 CAPS NOX analyzer uses superior Cavity Attenuated Phase Shift (CAPS) Spectroscopy to measure True NO2, NOX, and NO gases. The instrument combines direct NO2 measurements with highly efficient gas phase titration (GPT) to convert and measure the NO gas component. An automatic baseline reference cycle accounts and compensates for any potential baseline drift due to varying environmental conditions. 

CAPS technology is inherently accurate and sensitive, uses very little power, and requires far less maintenance than Chemiluminescence. The Model N500 raises the bar for NO2, NOX, and NO measurement accuracy, while simultaneously reducing instrument operation and maintenance costs.

TELEDYNE API N901 THC, CH4, NMHC ANALYSER

The Model N901 is a near-continuous hydrocarbon gas analyzer that measures the concentration of Methane (CH4) and Total Hydrocarbons (THC) in air. The concentration of the non-Methane (NMHC) component is calculated by the subtraction of CH4 from THC, with high sensitivity and accuracy. The hydrocarbons are measured using a Flame Ionization Detector (FID), in combination with gas chromatography (GC). The instruments range and performance are tuned specifically for use in ambient air quality monitoring assessments.

TEKRAN MERPAS PASSIVE AIR SAMPLER

The MerPAS Passive Air Sampler is the newest Tekran sampling solution developed to provide customers a simple device for measuring mercury in a wide range of environments. The sampler can be configured to sample either background ambient air or highly-contaminated industrial locations. Since collection is passive, MerPAS sampling is completely power-free allowing easy deployment in a wide array of locations.

Based on the design developed by researchers at the University of Toronto, the MerPAS sampler is the perfect sampling solution for locations not requiring high-resolution data, or for locations where greater spatial coverage is needed to complement a single location high resolution mercury monitor. After collection, the MerPAS sampler is analyzed in a laboratory for mercury content using thermal or wet chemical techniques.
