hydrogen detection

A hydrogen sensor is usually installed in situations where there is a risk of leakage or accumulation of hydrogen gas. Here are some examples of situations where installing a hydrogen sensor can be useful:

  1. Industrial environments: In industries where hydrogen gas is produced, stored, used or transported, it is important to monitor the level of hydrogen gas in the air. A hydrogen sensor can help detect leaks or abnormal accumulations of hydrogen gas early, ensuring the safety of workers and facilities.
  2. Hydrogen Fuel Cells: Hydrogen fuel cells are used in vehicles, portable devices and even as energy sources for buildings. Installing a hydrogen sensor near fuel cell plants can help detect leaks and reduce the risk of fire or explosion.
  3. Laboratories: In laboratories where hydrogen gas is used, it is important to monitor the gas concentration. A hydrogen sensor can help detect leaks and maintain a safe working environment.
  4. Battery charging stations: A hydrogen sensor is sometimes used when charging lead batteries to detect the presence of hydrogen gas. Lead-acid batteries, also known as lead-acid batteries, can produce hydrogen gas as a result of electrochemical reactions during charging.

It is important to follow the hydrogen sensor manufacturer's instructions regarding its installation, maintenance, and calibration. In addition, safety standards and regulations may apply depending on the specific application and the country in which the installation takes place. Consulting an expert in hydrogen technology or safety can also be helpful in determining the proper installation requirements for a hydrogen sensor in a specific situation. We can help you with this.

We offer the most comprehensive hydrogen detection range in the Benelux.

We have the right hydrogen detection for you.

De Sensistor hydrogen detection equipment is unique due to its very fast response and sensitivity (from 0,5 ppm H2). Due to the fast recovery time, measurements can be resumed immediately. The Sensistor hydrogen detectors are 100% hydrogen selective.

De H2scan hydrogen detection equipment is unique in measuring concentrations of hydrogen for both in-line and space monitoring. Unique is the hydrogen selectivity and an expected sensor lifespan of > 10 years.

De LC10 hydrogen leak detector is a “low budget” solution. Easily detects hydrogen leaks and is very compact and easy to use.

As a service, we offer the possibility of detecting hydrogen leaks or carrying out concentration measurements for you.

Hydrogen monitoring.

We are increasingly being asked to perform an H2 analysis (24-hour measurement) at battery charging areas.

During the charging of batteries for eg forklift trucks, oxyhydrogen (hydrogen) is formed by electrolysis. (NPR 3299 “Working safely when charging traction batteries”)

Hydrogen measurement

Oxyhydrogen is a mixture of the gases hydrogen gas (H2) and oxygen gas (O2), in a volume ratio of 2:1. Oxyhydrogen is an explosive mixture that, when ignited, reacts to form water. The combustion of oxyhydrogen gas produces a lot of energy: 286 kJ per mole of H2.

A small test tube with oxyhydrogen can easily be prepared by holding it upside down over a beaker (glass) with slightly acidified water containing two electrodes through which an electric current flows (see electrolysis). This creates hydrogen gas and oxygen gas in the correct ratio.

Detonating a small tube of oxyhydrogen is not that dangerous, except for possibly jumping glass. In larger quantities, the gas is very dangerous, even more so than pure hydrogen gas, because it is mixed with oxygen in the right proportion. A sandwich bag containing oxyhydrogen causes an explosion similar to that of a thunderclap (fireworks) and can therefore cause serious physical damage.

If there is not sufficient ventilation in the loading space and or insufficient fresh air, for example due to a small enclosed space, an excessively high hydrogen concentration can arise. At a hydrogen concentration of 4,1% to 72% in air, hydrogen is dangerous due to its explosive property.

To make sure that not too much hydrogen is formed, Leak Control offers a 12-hour hydrogen measurement. Measurements are carried out for 12 hours in the space where hydrogen can be formed. After the measurement has been completed, the measuring equipment is read and analyzed at Leak Control. The customer receives a report with the measurement results.
