Product Description

T625-O2 Fixed Long Life Oxygen Depletion Sensor

The T625-O2 Oxygen detector is used to for oxygen depletion or enrichment.  Applications include: laboratory rooms, where inert gases are used, cryo stores. Anywhere that has increased levels of Oxygen enrichment or risk of Oxygen depletion, including laboratories, cryo-stores, hospitals etc.

However you can not use Oxygen detector(s) to monitor for increase CO2 levels, as stated under BS EN 60079-29-2:2015section 4.4.4 Section D: “Oxygen detectors shall never be used to indicate displacement by CO2”.

Reliance on Oxygen depletion sensor to monitor the presence of CO2 has led to fatalities.

Advantages of using IGD Sensor Technology:

T625 MICRO systems and sensors require no setup, with just 1 click of the button the controller will find and automatically setup all the alarm levels for the connected sensors. This means that you do not need any prior knowledge in gas detection experience to install and setup the system. Wiring is made simple and cost effective, as the sensors are connected on one single cable run. Furthermore, if you do not have any electrical knowledge the system can be supplied in a “plug & play” format, using pre-made cables. This allows you to deploy the system quickly and effectively, as no wiring is needed.

Sensor Technology:

The T625-O2 Oxygen depletion sensor represents a major advancement over older less reliable lead based sensor technology. Our T625 Oxygen detector is based on new advances in solid polymer technology giving long life more than 5 years coupled with excellent accuracy and reliability. The T625 Oxygen sensor finds applications in industry where Oxygen levels may become depleted thus presenting a serious hazard. Saving you costs on replacement sensors, which will improve the building maintenance cost and safety.

Alarm levels:

Alarm 1 = 19.5%

Alarm 2 = 18.5%

Falling-Latching alarm Type

Systems Accessories:

IGD supply a range of accessories for your gas detection system including:

Bump Test Kits: – this allows you to test your system periodically, allowing you to check the system is fully functional and your cause and effects.

Splash Guards: –  Splash guards protect sensors, which are placed at low levels, from both rain water and splashes, including cleaning fluids.

Beacon Sounders/Audible Visual Alarms: are be fitted to our system easily using our Nodes, it will automatically find them. Supplying the system with a visual alarm indicator.

Annual Service of the System:

Any gas detection system must be service every 6 months under both the PUWER Act and BS EN 60079-29-2. All IGD equipment must be service by certified IGD engineers (They will be carrying IGD Certified cards or phone IGD for assistance). We can offer a tailored service contracts to meet your needs.
