Surface roughness vision measurement in different ambient light conditions
Machine vision method was used to measure the surface roughness for different Φ38 mm grinding axes in different ambient light conditions. To analyse the effect of ambient light, a method based on the grey-level co-occurrence matrix was applied at the first step. Then, a new calculation method was proposed to minimise the effect of ambient light during measurement. At the calibration stage, ...

Study of polycyclic aromatic hydrocarbons in atmospheric particulate matter of an urban area with iron and steel mills
Polycyclic aromatic hydrocarbons (PAHs) were analyzed from ambient air particulate matter <10 µm (PM10) and the total suspended particulate (TSP) phase continuously for a period of six months (May–October 2010) at five sampling sites located in the urban area of Divinópolis (Minas Gerais), southeastern Brazil, near iron and steel mills. The carcinogenic potency of priority PAHs relative to ...

LCD USB Temperature Humidity Data Logger
The USB Temperature Humidity Data Logger is an ideal temperature logger for environmental temperature and humidity monitoring because it comes with a USB plug and can generate temperature and humidity data reports for the entire supply chain, helping users analyze the ambient temperature of items. Temperature and humidity monitoring is very important for many items during storage or ...

Smog, Cough, Mask: What Can FPI Provide for the Deteriorating Air Quality
It is an observable fact that many places are still exposed to poor air quality, which has claimed people’s health and damaged the sensitive ecosystem. Therefore, many countries have rolled out their goals for air quality management with a common wish to improve the living standard for more. As the world’s leading advanced equipment provider, and a producer of air quality management ...

What is the effect of elevation on oxygen readings?
Recently we received a call from a customer who was in quite a panic. They had taken their Model 901 O2 analyzer from Minnesota to Denver, and turned it on to see quite a difference in the ambient oxygen readings when powering the analyzer on. While our calibration certificate states the elevation that our O2 analyzers are calibrated, certainly many customers don’t read the certificate ...

Economic Evaluation of Air Quality Targets for CO and Benzene
The study is to identify and estimate the costs and benefits of meeting ambient air quality standards for carbon monoxide (CO) and benzene in the EU. The study should take the range of scientifically-based limit values for ambient air quality as given and analyze the costs and benefits of attaining these standards. These costs and benefits should be compared with the costs (loss of benefits) of ...

Freezer BlueTag T10 Bluetooth Temperature Data Logger
Freezer mainly serves items that are easily affected by temperature and deteriorate, such as food, medicine, etc. The working principle of a Freezer is that it requires temperature control equipment to always maintain a constant appropriate temperature. Different items require different temperatures to be stored. Temperature monitoring is a must-do task in the cold room. Bluetooth Temperature ...

Weekday/Weekend Differences in Ambient Air Pollutant Concentrations in Atlanta and the Southeastern United States
Abstract The authors quantified changes between mean weekday and weekend ambient concentrations of ozone (O3) precursors (volatile organic compounds [VOC], carbon monoxide [CO], nitric oxide, and oxides of nitrogen [NOx]) in Atlanta and surrounding areas to observe how weekend precursor emission levels influenced ambient O3 levels. The authors analyzed CO, nitric oxide (NO), and NOx ...

Gas Analysis – the Cornerstone of Battery Safety Testing
Li-Ion batteries (LIBs) are the dominating technology in battery-operated devices. LIBs have become the preferred choice for various applications, including consumer electronics, electric vehicles (EVs), and renewable energy storage systems. LIB usage and research have shown significant growth in recent years and are expected to continue at a high pace in the near future. Major manufacturers ...

LinkBus RIMS case study
For a variety of reasons, decreasing resources are causing plant operators in the process and utility industries to look for more efficient ways of monitoring and servicing their instrumentation. The analyzer maintenance department may have been reduced in size, merged with another department or perhaps no longer exists at all, and reassignments and relocation of staff can lead to a loss of ...

FTIR gas analyzers support management of fire at UK waste facility - Case study
A multi-agency Air Quality Cell (AQC) was first established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents. Arrangements have been made in England to bring together experts from the Environment Agency (EA), Public Health ...

Water Quality Models
' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...
