Portable single gas detectors are used for personal protection and have the ability to detect a single gas hazard. Typically they are small, lightweight and robust. These devices are generally worn directly on the worker’s clothing or attached to Personal Protective Equipment (PPE), close to the worker’s breathing area (30cm).
Single gas detectors continuously monitor ambient air. When the gas concentration exceeds a pre-set alarm event on the device, it will alarm (by visual, audible and/or motion). This allows workers to react directly to risks.
Single Portable Gas Detectors Are Available in Two Types
Overall Cost of Ownership
In many cases, single gas detectors are purchased for immediate safety, operational or legislative need, but often, little thought is given to keeping them operational and within performance requirements for their life.
There are 3 main costs.
- Calibration or performance testing
- Maintenance and replacement costs
- Loss of product or replacement when units are being serviced
All of these are factors that need to be considered by the user.
Disposable single gas detectors are generally only available for Hydrogen Sulphide (H2S), Carbon Monoxide (CO), Oxygen (O2) or Sulphur Dioxide (SO2).
Serviceable gas detectors typically detect up to 15 gases.
The battery and sensors within disposable gas detectors will generally run for approx. two years. Once they’re switched on, they’re on for their lifetime. Serviceable gas detectors have consumable parts, so the battery and sensors can be replaced. This allows ongoing use until they become damaged beyond economic repair.
Disposable single gas detectors only offer event logging. If you require datalogging rather than event logging, consider a Serviceable single gas detector.
IP67 rating means that the gas detector can be submerged in up to 1m of water and is totally protected from particulates. Some of our single gas detectors have this protective rating.
Hibernation mode allows the gas detector to be placed in a ‘hibernation mode’ when not in use. A hibernation case may need to be purchased separately. This allows for the gas detector’s life to be increased from 2 years up to a maximum of 3 years.
