Product Description

Addressable Fixed Chlorine Detector (T625-CL)

Chlorine gas is extremely toxic with short term exposure levels as low as 1ppm (See EH 40 for long term and short term exposure limits). Chlorine gas detection therefore requires exceptional low level detection performance which our T625-CL Addressable Chlorine Detector provides. The T625-CL Addressable Chlorine Detector features advanced sensor technology; combined with high performance electronics making it the engineers sensor of choice.

Where is Chlorine Gas Used:

  • Swimming Pools
  • making plastics
  • pharmaceuticals
  • insecticides
  • and more.

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.

Furthermore rather than having an annual service visit, you can now swap out the front of the detector and replace it with a new front every year. Check out our article on how our sensor front swap and 1 click technology, helped our client with their swimming pool plant room safety.

Sensor Technology:

Chlorine detectors are commonly used for personnel protection in the water industry and so have to perform in a unique environment presenting many challenges. IGD’s Chlorine detection technology uses a highly specific sensor resulting in freedom from interference from other gases. Excellent temperature performance gives a sensor baseline which is virtually unaffected by changes in temperature. IGD’s Copyrighted sensor software algorithms and ARM based hardware ensure freedom from false alarms and reliable, consistent detection performance.

Alarm levels:

Alarm 1 = 0.5ppm

Alarm 2 = 1ppm

Alarm Type: Rising – Latching Alarm


Systems Accessories:

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

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.
