  • Air monitoring equipments for workplace and personal exposure monitoring

    Many occupations involve the use of hazardous substances or processes, where pollutants may be ingested, inhaled or absorbed through the skin. General ambient pollutants can also have health implications in otherwise non-hazardous workplaces. Occupational exposure limits regulate many pollutants based on an eight-hour working day. Personal exposure assessments can be made over an eight-hour period (Time Weighted Average (TWA) exposure) using our simple to use monitoring equipment.

  • Noise and vibration problem solutions for local authorities and government

    The increase in housing stock required by the government is leading to developments being considered in a wider variety of locations and can provide challenges in assessing and agreeing levels of acceptable noise and vibration exposure. With the introduction of the National Planning Policy Framework (NPPF) and the Noise Policy statement for England (NPSE) clients are faced with rapidly changing local authority requirements.

  • Pulsar noise testing equipment for construction industry

    The construction sector and its wide range of associated activities are very varied and from a noise monitoring perspective offer many unique challenges. However, Pulsar Instruments have a solution; a construction Pulsar noise meter with the ability to effectively assess the following two key categories; Noise at Work (potential for noise induced hearing loss due to long term exposure to noisy activities). Environmental Noise (the potential to cause annoyance to surrounding areas or buildings during site work).

  • APHA Color #3020

    Measurement of APHA color either on-line or in a laboratory setting using a photometer. Background: APHA is sometimes referred to as the Platinum Cobalt (Pt/Co) or Hazen scale. Also referred to as a “yellowness index”, the APHA color scale is a common method of comparison of the intensity of yellow-tinted samples to assess the quality of liquids that are clear to yellowish in color. Originally developed to determine the purity of municipal water supplies, it is now used as a metric for purity in the water, chemical, oil, plastics, and pharmaceutical industries. APHA color quantifies the appearance of trace amounts of yellowness, which is a visual indicator of product degradation due to exposure to light or heat; the presence of impurities and negative effects of processing. As such APHA color is often used as a product release specification. APHA is a single number yellowness index. The units are based on a dilution of a 500ppm solution of PtCo.
