Published requirement descriptionThis Contract award notice is linked to PPN Notice identifier: 2025/S 000-028704 linked here: www.find-tender.service.gov.uk/Notice/028704-2025 ↗
UU are looking to source sensor equipment capable of detecting & measuring Nitrous Oxide in liquid.
The requirement of detection in liquid is fundamental to this product; sensors for gas state do not meet this requirement.
UU are looking for 120 sensors for immediate requirement, along with appropriate fitments, controllers, pipe mounting equipment, cabling and calibration kits. The initial requirement should also include consumables to run the sensors for 12 months. Our research shows probe heads have a usable lifespan of 6 months. There will likely be on ongoing requirement for spares and consumables for 5 years.
Our market intelligence leads us to the conclusion there is only 1 suitable product on the market currently, from Unisense, shown here: unisense-environment.com/products/n2o-wastewa… ↗
We are expecting the cost to come in at approximately £1M based on the product set from Unisense over 12 months. With a consumables requirement of a further £1M over the following 4 years.
This notice is designed to test our sourcing intelligence with the market for competing product availability.
