    General Monitors Observer-i Ultrasonic Gas Detector

    General Monitors Observer-i Ultrasonic Gas Detector

    The Observer-i Ultrasonic Gas Detector from General Monitors uses Gassonic ultrasonic technology to instantly detect pressurised gas leaks. This highly precise acoustic detector works when traditional gas detection equipment is not suited or dependent on ventilation. 

    The GM Observer-i can analyse sounds as low as 12 kHz due to no common high pass filters being used. Broader leak detection can be activated which in turn increases sensitivity to smaller gas leaks, without interference from unwanted background noise. 

    This detector requires no alarm setpoints or trigger levels to be configured and alarm parameters do not need to be adjusted. Additionally, the Observer-i is backwards compatible with earlier versions of the Observer, thanks to its classic mode setting. 

    Key Features
    • Improved detection range and background noise rejection - preventing false alarms
    • Integrated Senssonic self-test 
    • The capability of storing faults, sound checks, calibrations, and alarm history
    • Detects gas leaks from 2 bar (29 psi) pressure

    ORDER CANCELLATION AND GOODS RETURN

    Should you wish to cancel an order or return unwanted goods please follow the procedures detailed below to help us ensure cancellations/returns are processed as quickly and efficiently as possible.

    Simply log on to your customer account, note the order reference number and email the full cancellation details to [email protected] or contact us on 0141 771 7749. Assuming the order has not been despatched we will cancel.

    You have the right to cancel the purchase of goods without having to give a reason at any time within the “cooling off period” of fourteen working days, beginning the day after you take delivery of your order.

    You must notify us of your cancellation in writing via email to [email protected] or to our contact address. (Details Here)

    If you are in possession of the goods you are under the duty to retain them and take reasonable care of them.

    You must send the goods back to us in their original condition to our contact address at your own cost (unless we delivered the item to you in error or the item is damaged or defective) as soon as possible once you have cancelled the contract.

    Alternatively we will collect the goods from you which will incur a charge no greater than the actual cost of arranging the collection and shipping. In this case you must make the goods available for collection. We will contact you to make further arrangements.

    We reserve the right to make a charge not exceeding our direct costs of recovering the goods if you do not return the goods or return them at our expense.

    Upon receipt of returned items in satisfactory condition we will arrange a full credit by the same method used to pay for the goods originally. Any credit due will be processed within a maximum of thirty days.

    Note: If you wish to return goods for refund or exchange after 14 days, a re-stocking fee of 20% of the full order total will apply.

    If upon receipt of goods you find them to be faulty, damaged or if you have been incorrectly supplied an item, you should notify us within 24 hours by contacting 0141 771 7749 or [email protected] and quoting your order number and contact details.

    Frontline Safety will arrange uplift of any damaged or wrongly received goods and if on inspection of goods we also find them to be damaged, faulty or incorrectly supplied, we will offer replacement goods or provide a full refund.

    We recommend you inspect all goods prior to signing for and accepting delivery. If there is any visible damage to the outer packaging, ensure goods are sign for as damaged. In instances where it isn’t possible to sign for goods as damaged, these should be signed for as unexamined.


    Note: If your goods happen to develop a fault out with the standard returns period but within supplied warranty period or if you require any additional assistance, please contact us on 0141 771 7749 or email [email protected]

    IMPORTANT INFORMATION

    All postage, handling, customs and duty charges for all returned goods are the responsibility of the customer. We recommend using a fully traceable, insured service as goods are your responsibility while in transit.
