  • Gradko - Nitrogen Dioxide Diffusion Tubes

    Gradko - Nitrogen Dioxide Diffusion Tubes

    Nitrogen dioxide diffusion tubes provide long-term monitoring options with detection limits in the low parts per billion to parts per million range. These cost effective devices do not require specialist skills or time commitment and therefore give the user an efficient method for air quality monitoring.

  • Gradko - Volatile Organic Compound (VOCs) Measuring

    Gradko - Volatile Organic Compound (VOCs) Measuring

    Volatile organic compounds (VOCs) in the range C2-C28 can be measured using a variety of sorbents to meet the specific applications required by the customer. Polyaromatic hydrocarbons (PAHs) can also be measured using a specific sorbent.

  • Gradko - Acid Gas Diffusion Tubes

    Gradko - Acid Gas Diffusion Tubes

    This tube can simultaneously measure a range of acid gases – Hydrogen fluoride, Hydrogen chloride, Nitric acid, Hydrogen bromide, Phosphoric acid and Sulphuric acid (HF, HCl, HNO3, HBr, HPO4 and H2SO4).

  • Gradko - Ammonia Diffusion Tubes

    Gradko - Ammonia Diffusion Tubes

    Ammonia diffusion tubes are suitable for long-term monitoring of ambient Ammonia pollution (sampling times are 2-4 weeks). These Ammonia samplers are simple to use, requiring no specialist skills or power supply, making them an efficient monitoring option. With very low detection limits (in the low parts per billion range), even low levels of Ammonia pollution can be identified.

  • Gradko - Anaesthetic Gases Monitoring System

    Gradko - Anaesthetic Gases Monitoring System

    Many professionals, including doctors, nurses, dentists and vets use anaesthetic gases on a regular basis. Continuous exposure to these gases can be harmful, so monitoring of both personal exposure and ambient concentrations is important.

  • Gradko - Model DC1700 - Airborne Particle Counter

    Gradko - Model DC1700 - Airborne Particle Counter

    Scientific studies have found an association between exposure to particulate matter emissions and significant health problems. The Air Particle Counters are affordable instruments which can monitor indoor air quality in homes and workplaces.

  • Gradko - Formaldehyde Measurement and Aldehydes

    Gradko - Formaldehyde Measurement and Aldehydes

    The largest emissions of Formaldehyde are associated with its manufacture and subsequent use, natural emissions are lower. This tube is used for active (pumped) sampling over a few hours to identify levels of Formaldehyde and other Aldehydes. Concentrations can be measured in the low parts per billion (ppb) range and above.

  • Gradko - Ozone Diffusion Tubes

    Gradko - Ozone Diffusion Tubes

    Ozone tubes are Palmes-type diffusion tubes used for long-term monitoring over 2-4 weeks. Ozone can be detected in the low parts per billion to low parts per million ranges. Specifically designed for Ozone absorption, the tubes are inexpensive and require no specialist skills or training, an ideal air monitor for large areas or for long-term studies.

  • Gradko - Sulphur Dioxide Diffusion Tubes

    Gradko - Sulphur Dioxide Diffusion Tubes

    Ambient air monitoring using our Sulphur dioxide diffusion tubes is a simple means of monitoring that requires no further maintenance after installation – an easy, cost-effective method. These Palmes-type tubes are designed for long-term monitoring, and offer measurement of Sulphur dioxide in the low parts per billion to parts per million range.

  • Gradko - Ammonia Rapid Air Monitor

    Gradko - Ammonia Rapid Air Monitor

    Gradko’s new range of Rapid Air Monitors (RAMs) brings together the ease of passive sampling with the added advantage of very short monitoring periods.
