TPI SP341LK Legionella Temperature Test Kit

The TPI SP341LK Legionella Temperature Test Kit provides an easy, accurate way to monitor water system temperatures. Designed for compliance, the kit helps duty holders meet legal obligations by testing for Legionella at outlets like taps, tanks and pipework. Its compact design and smart app connection make routine checks faster and more organised.

Thanks to Bluetooth 4.2 connectivity, the TPI SP341LK transmits live data directly to your phone. Test results are stored within the TPI View app and grouped by site, simplifying audits and reducing paperwork. This digital approach allows both single and differential temperature readings to be recorded clearly and efficiently.

Designed for Field Accuracy

The SP341 smart probe connects to any sub-mini Type K thermocouple, providing flexibility across a wide range of test points. The FK13M immersion probe and CK15M surface probe included in the kit enable quick testing of both water and surface temperatures. When field-calibrated, it delivers ±1°C accuracy between -1 and 49°C, ensuring trustworthy readings during crucial checks.

Practical and Ready to Use

With 75 hours of battery life and a simple AAA power source, the TPI SP341LK is ideal for extended use. Its slim probes make access easy even in tight locations, while the A926 zipper case keeps everything organised. This comprehensive kit is built for users who need reliability and speed in real-world environments. Every test is logged and stored with ease, making temperature compliance both simple and traceable.
