  Alcoholimetry

  Breathalyzers: Precision and Safety in Alcohol Measurement
  A breathalyzer is a high-precision device used to measure the concentration of ethanol in the body, known as Blood Alcohol Content (BAC). This measurement is performed quickly and non-invasively by analyzing the breath exhaled (Breath Alcohol Content – BrAC) during a blow.

  The detection of alcohol in the body is carried out using two main analytical methods: electrochemical sensor technology or infrared absorption, both widely recognized for their reliability and accuracy.

  The scientific basis of breathalyzers lies in the physiological relationship between the alcohol concentration in alveolar air and the alcohol level in the blood. While this relationship may vary across countries due to physiological differences in the population, it allows for an effective conversion. In Portugal, it is established that 1 mg of alcohol per liter of exhaled air (BrAC) corresponds to 2.3 g of alcohol per liter of blood (BAC):

  1 mg/L (BrAC) = 2.3 g/L (BAC)

  Although breathalyzers are primarily used for monitoring alcohol levels in road traffic enforcement, their application has been expanding to other sectors. A growing number of companies are adopting this technology to enhance workplace safety, ensuring that employees are not under the influence of alcohol while performing their professional activities.

  By implementing breathalyzers, organizations promote safety, responsibility, and risk prevention, making these devices essential allies in protecting lives and ensuring compliance with regulations.

  Conductivity Meters

  Easy-to-use, waterproof and high-quality conductivity meters. Conductivity measurement is an extremely widespread and useful method, especially for quality control purposes.
  
  Surveillance of feedwater purity, control of drinking water and process water quality, estimation of the total number of ions in a solution or direct measurement of components in process solutions can all be performed using conductivity measurements.

  The high reliability, sensitivity and relatively low cost of conductivity instrumentation makes it a potential primary parameter of any good monitoring program. Some applications are measured in units of resistivity, the inverse of conductivity. Other applications require the measurement of total dissolved solids (TDS), which is related to conductivity by a factor dependent upon the level and type of ions present.
  
  Conductivity measurements cover a wide range of solution conductivity from pure water at less than 1x10-7 S/cm to values of greater than 1 S/cm for concentrated solutions.
  
  In general, the measurement of conductivity is a rapid and inexpensive way of determining the ionic strength of a solution. However, it is a nonspecific technique, unable to distinguish between different types of ions, giving instead a reading that is proportional to the combined effect of all the ions present.

  ORP/REDOX Meter

  ORP, or Redox Potential, is a measurement of water’s ability to oxidize contaminants. The higher the ORP, the greater the number of oxidizing agents.

  Checking ORP is a simple method to monitor the effectiveness of a sanitizer or the quantity of anti-oxidants in a liquid. In generalized terms for humans, a higher ORP is better for outside of the body, while a lower ORP is preferred for consumption due to the high anti-oxidant value.

  There are numerous applications for ORP, each with its own specific optimum value. For example, the minimum ORP for pool & spa disinfection (set by the World Health Organization) is 650 mV. Though the WHO has not set a standard for ORP in drinking water, anything below -550mV is considered too strong and not recommended for drinking.

  TDS Meters

  A TDS Meter indicates the Total Dissolved Solids (TDS) of a solution, i.e. the concentration of dissolved solid particles.

  Dissolved ionized solids, such as salts and minerals, increase the electrical conductivity (EC) of a solution. Because it is a volume measure of ionized solids, EC can be used to estimate TDS. Dissolved organic solids, such as sugar, and microscopic solid particles, such as colloids, do not significantly affect the conductivity of a solution.

  The most accurate way to measure TDS of water in a laboratory is to evaporate the water leaving behind dissolved solutes as residue and then weighing the residue.

  Oxygen Meters for...

  Oxygen saturation (symbol SO2) is a relative measure of the amount of oxygen that is dissolved or carried in a given medium. It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. The standard unit of oxygen saturation is percent (%).

  Oxygen saturation can be measured regionally and noninvasively. Arterial oxygen saturation (SaO2) is commonly measured using pulse oximetry. Tissue saturation at peripheral scale can be measured using NIRS. This technique can be applied on both muscle and brain.

  Monitoring of the oxygen amount in the air is, extremely important, since it is not always that harmless and too much oxygen in the air may indicate a dangerous situation. The measurement of oxygen is particularly important in the workplace monitoring and process control, medicine, food technology, ventilation and sport. We offer measuring devices and special sensors that can be used in wide applications.

  Salinity Meters

  Salt meter range you can measure salt content following the direct method with the help of the optical Salinity meter.

  The salt meter is suitable for measuring salt contents in aqueous solutions or viscous media. We recommend using the salinity to measure sea water or solutions with high salt content. With the indirect method you will obtain the conductivity value which will proportionally increase with the salt content.

  You can choose between a salt meter for flowing or pure water (it is important for certain industries). We offer a salt meter with different conductivity measurement fields. It is important to know that a salt meter usually emits electric conductivity as a measurement value in µS/cm.

  Fluoride

  The chemical symbol fluorine F is very abundant in the earth's crust, representing about 300 mg/kg3 of its composition. It is the most electronegative chemical element of the periodic table and the most reactive, not being free, but always combined with calcium, sodium, aluminum, as fluoride (F-) and sometimes as part Of the composition of some silicates.

  Fluorides are ubiquitous, present in the soil, forming part of the composition of many minerals, such as fluorite (CaF2), cryolite (Na3Al F6), fluorapatite Ca5(PO4)3 F; In air (particulate form) and dissolved in water.

  Their existence in the environment is due in part to natural sources, including volcanic activity and marine aerosols and anthropogenic or man-made sources resulting from all man's activity, including the manufacture of steel, primary production of aluminum, copper and nickel production, pesticide production, the production and use of phosphate fertilizers, the manufacture of glass, ceramics, glue and adhesives etc.

  Fluoride, which occurs in biological fluids such as fluoride ion F-. In cases of occupational exposure or food and water for human consumption, excessive levels of fluoride in the body may cause health risk. Fluoride is easily determined using the meters available from EMI LDA.

  TPM (Total Polar...

  Measuring the TPM (Total Polar Material), the content of total polar components of oils for food preparation, determines the maximum point of use of the oil, avoiding saturation and leaving the prepared food suitable for the consumer. TPM quantifies the presence of polar molecules in the oil: the higher this percentage, the greater the level of degradation of that oil. We recommend that the oil be replaced when the TPM reaches 25%, in accordance with European legislation.

  Cooking oil develops its best potential between 14% and 20% TPM. Using the TPM meter to detect when the oil should be replaced also ensures that there is no wasted oil and unnecessary costs.
