Closed System LTHW Testing Kit (Non-UKAS)

Monitor and maintain the health of your low-temperature hot-water (LTHW) closed-loop system with this testing kit. Designed for facilities engineers, building services teams and maintenance contractors, this kit supports essential water-quality checks, including pH, total dissolved solids (TDS), conductivity, iron content, and inhibitor levels. Optimise system efficiency, prevent corrosion and scale build-up, and ensure your system remains in effective working order.

When you place an order, we’ll dispatch a sealed sterile container appropriate to the sample(s) ordered. Each kit includes:

• Clear instructions on how to take the sample

• Free return shipping of the samples back to the laboratory

• Free technical support via phone, email or messaging platforms regarding sample locations and method of sampling

• Free technical support on understanding the results and any next-step recommendations

Please note: The submission time is the period between taking the sample (filling the bottle) and the laboratory receiving it. Samples received outside the recommended submission time may not align with certain UKAS, British Standard, ISO or HSG guidelines.
