Hydrazine – N2H4

Find here the essential information on hydrazine – N2H4) or diazane: characteristics, effects on health, detection devices & systems – hydrazine gas detector – and proper respiratory protective equipment (gas mask or powered air purifying respirator with K-P3 combined filter).

hydrazine gas detector, sensor and N2H4 respiratory protection

Hydrazine properties

Best known for its use as rocket jet fuel, hydrazine (N2H4) – also known as diazane – is also used in the petrochemical and pharmaceutical industries as a synthesis intermediate and in the rubber industry as a blowing agent to produce polymer foam. Thanks to its characteristics – mainly its liquid state at ambient temperature – this gas is used to produce fuel cells.

Hydrazine exposure hazards

Colorless and featuring an ammonia smell at low concentration levels, hydrazine (N2H4) is very soluble into water or alcohols, which may lead to explosive vapors production. Even if it is flammable either liquid or gaseous (H226), this gas is very toxic if inhaled, swallowed or in contact with skin (H331/301/311) and classified as 2B (possibly carcinogenic to humans) by the IARC*. It can cause severe skin burns and eye damage as well (H314).

Hydrazine effects on health (N2H4)

Hydrazine gas detector - N2H4

As this gas is not detectable through smell, only a hydrazine gas detector can accurately measure concentrations of this gas. Moreover, even if this gas is very explosive (at 1.8% volume), its explosivity monitoring would be pointless as hydrazine is toxic. For this reason it is recommended to use a portable or fixed hydrazine detection equipment.

VOC detector MX6 volatile organic compounds

The MX6-VOC accurately measures presence of volatile organic compounds (VOC) in ambient air using a 10.6 eV PID photoionization lamp from 0 to 2,000 ppm in 0.1 ppm increment.

  • Detection of many VOCs from 0 to 2,000 ppm
  • Serial sampling pump for remote samples
  • STN color LCD graphic display
  • User-friendly menu for easy access
  • Certifications: IECEx/ATEX : EEx ia d IIC T4
Additional information

Volatile organic compounds – most commonly known as VOCs - gather thousands of substances and gases. They can be found in many fields of activity. The MX6-VOC gas detector is a classic single-gas detector especially designed to detect these substances. Thanks to its ion-lithium rechargeable battery, it can operate during 12 hours according to the application.

The MX6-VOC gas detector needs to be calibrated twice a year in order to ensure proper operation. The photoionization sensor (sensor technology for VOC detection) can detect volatile organic compounds with a ionization potential below 10.6 eV. The MX6-VOC measuring range is set between 0 and 2,000 ppm in 0.1 ppm increment.

An integrated gas sampling pump guarantees measurements accuracy. This pump also enables to draw remote samples before intervention. According to the configuration, it is possible to add up to 5 more gases to the MX6-VOC.

This VOC detector features 3 different alarms. The powerful audible alarm is designed to alert even in noisy environments. The high visibility red LED visual alarm and a vibrating alarm are also made to ensure a high level of protection.

Its large colored screen displays concentrations in ppm (part per million) or in percentage volume. Digital values can be replaced visually thanks to the user-friendly menu.

The MX6-VOC gas detector is impact-resistant thanks to an over-molded polycarbonate housing. This monitor meets almost any EU current gas detection related standards.

The CUB is a portable VOC detector with photoionisation detection (PID) technology designed to quickly and accurately detect volatile organic compounds, keeping workers safe within working environment. With parts-per-billion (ppb) sensitivity, the CUB personal gas monitor gives an early warning of exposure to hazardous gases. Comfortable and unobtrusive to wear, the CUB can be easily worn close to the breathing zone thanks to its crocodile clip and is to date the smallest, lightest, personal VOC detector available.

CUB personal detector has a dynamic range of 0 to 5,000 ppm – the widest on the market – measuring 480 selectable compounds. When worker exposure exceeds pre-set limits, an audiovisual and vibrating alarms alert users on hazardous gases concentrations. Readings are displayed on a bright, backlit LCD display with selectable data logging time. Its long duration battery enables a continuous operation during 16 hours when fully charged.

CUB’s patented photoionisation detection (PID) sensor technology has been independently verified as best performing for speed, accuracy and humidity resistant operation. The PID sensor’s Fence Electrode features a humidity resistant and anti-contamination design providing extended run-time in the most challenging environments. Thanks to this technology, the CUB gas detector offers fast response to hazardous gases and vapors (less than 13 seconds).

The CUB personal VOC monitor is available as a standard instrument with 10.6 eV lamp for accurately detecting a wide range of volatile organic compounds (VOCs) in parts per million (ppm) levels. The CUBTAC ppm variant version with 10.0 eV lamp can accurately detect total aromatic compounds (TACs), including benzene. Both models can be quickly and easily upgraded with parts per billion (ppb) sensitivity.
