The Hydrosense Legionella refill ONE Multi pack is available in Thailand through BCST, providing replacement consumables to continue scheduled serogroup 1 monitoring at 1,000 CFU/L sensitivity with Hazard Index indication at 10,000 CFU/L.

Legionella Refill ONE Multi — Continuous Monitoring Without Interruption

The Hydrosense ONE Multi Industrial Kit Refill Pack supplies the single-use consumable components required to continue operating your Hydrosense ONE Multi Legionella Industrial Kit after the initial five tests are completed. The permanent pipework adaptor remains installed at the water outlet between testing cycles. Only the consumables require replacement.

An uninterrupted testing schedule is not simply a best practice — for hotels, hospitals, cooling tower operators, and commercial building managers across Thailand, it is a legal and operational obligation. An interrupted testing cycle creates a compliance gap in your water management programme records that cannot be retroactively closed. Furthermore, maintaining consistent stock of refill consumables ensures your facility meets its duty of care obligations without disruption. Consequently, facilities with multiple water outlets benefit most from keeping refill packs on hand at all times.

What Is Included

Consumables for five additional complete tests:

• Test strips × 5
• 1ml buffer syringe × 5
• Filter × 5
• Hazard Index score card
• Instructions

The pipework adaptor and filtrate bottle from the original kit are reused. Contact BCST if replacement hardware is required.

Performance When Used With The ONE Multi Industrial Kit

• Detection: Legionella pneumophila serogroup 1
• Sensitivity: 1,000 CFU/L (100ml sample)
• Hazard Index: 10,000 CFU/L confirmed level
• Result time: 25 minutes
• VBNC Legionella detection included

Why VBNC Detection Matters

Viable but Non-Culturable Legionella are bacteria that are alive and capable of causing infection but remain undetectable by standard laboratory culture methods. Additionally, VBNC bacteria are particularly common in water systems that have undergone chemical treatment — the bacteria enter a dormant state in response to biocide exposure and therefore evade standard plate count testing. The Hydrosense filter technology detects VBNC Legionella in every test cycle, providing a more accurate risk assessment than culture alone. The World Health Organization recognizes Legionella pneumophila as a priority waterborne pathogen requiring active monitoring programmes.

Compatibility

This refill pack is compatible with the Hydrosense ONE Multi Legionella Industrial Kit only. It is not compatible with the ONE Ultra Industrial Kit or the PRO Ultra Industrial Kit. Verify your original kit model before ordering. For the ONE Ultra Industrial Kit refill, see the Hydrosense ONE Ultra Industrial Kit Refill Pack available from BCST.

Important Note

For environmental water testing only. Not for human diagnostic use. Positive results require immediate response in accordance with your facility’s water safety management plan and consultation with a qualified water hygiene professional.
