Ion Science gas detection equipment includes the following:

  • PID / VOC detectors
  • Benzene monitors
  • Gas leak detectors
  • Ground gas monitors
  • Hydrogen flux monitors
  • Mercury analysers

Ion Science instruments are designed for use across a wide number of industries and applications, wherever you have a need to detect gases and vapours, including:

  • Oil and gas
  • Chemical and petrochemical
  • Health and safety
  • Industrial hygiene
  • Environmental
  • Pharmaceutical
  • First response
  • Hazardous materials

PID technology

IonPID, the miniature PID sensor from Ion Science is revolutionising the gas-detection market. The sensor is found in all of the company’s PID instruments and has been adopted by leading gas-detection manufacturers worldwide, making it the most widely used PID sensor.

Ion Science PID sensor technology has received independent verification as the best performing on the market, proven to outperform all others with regards to speed, accuracy and giving the best performance within humid environments.

Humidity-and-contamination-resistant gas sensors

IonPID incorporates unique patented fence electrode technology with three-electrode format and anti-contamination design, enabling maximum resistance to humidity and contamination. The sensor is highly sensitive, with rapid response and clear down, giving outstanding performance in the field.

Easy to service gas sensors

The IonPID sensor is fully serviceable with its electrode stack / pellet and lamp easily replaced in seconds even while out in the field, minimising instrument downtime.

Service and support

Ion Science is committed to developing the highest-quality instruments that give clients the most accurate, reliable results backed by an unrivalled level of customer service and support.

The Ion Science head office and manufacturing plant is located near Cambridge, UK, with additional branches in the US and Germany. A network of Ion Science distributors can be found in most countries around the globe.

One Instrument for Benzene and TACs Detection

Tiger Select is a revolutionary handheld screening device with two-mode operation for the rapid detection of benzene and total aromatic compounds (TACs), providing reliable data that you can count on.

Cub Personal PID monitor

Cub, the smallest, lightest and most sensitive personal PID monitor, enables fast and accurate detection of volatile and total aromatic compounds, including benzene.

Detecting Benzene in Refinery Atmospheres

Benzene is a critical industrial chemical which is commonly found throughout the petrochemical industry. It is however, extremely hazardous and a recognised human carcinogen.

Revolutionary Handheld VOC Detector

What makes the Tiger so revolutionary? With its built-in fence electrode technology and anti-contamination design, Tiger provides rapid, accurate detection of VOCs with a high resistance to humidity and contamination.

Portable Mercury Vapour Analyser

MVI accurately detects mercury vapours in just three seconds. MVI does not saturate or require regenerating, eliminating instrument downtime.

PID in Industrial Hygiene

Industrial (or occupational) hygiene places the emphasis on prevention of ill health from work, through recognising, evaluating and controlling the risks.

Ion Science MVI Used for Accurate Results in Challenging Environments

The Ion Science Mercury Vapour Indicator (MVI) has surpassed customer expectations at mercury decontamination specialist company No Heat Resources, achieving outstanding results in the field in the harshest of environments, even with extremely high levels of mercury vapour.

Benzene and TAC Detection in one Instrument

Ion Science has introduced the revolutionary new Tiger Select for the detection of both benzene and total aromatic compounds (TACs) in one hand-held instrument.

Ion Science Introduces Personal PID Monitor

Leading UK manufacturer of technologically advanced gas detection equipment Ion Science has introduced Cub, the world's smallest, lightest and most sensitive personal PID monitor for fast and accurate detection of volatile organic and total aromatic compounds for the protection of workers.
