TPI SP341LK-PLUS SMART Legionnaires Temperature PLUS Kit

TPI SP341LK-PLUS SMART Legionnaires Temperature PLUS Kit

The TPI SP341LK‑PLUS SMART Legionnaires Temperature PLUS Kit is designed to carry out routine temperature monitoring on domestic and commercial water systems. At the core of this kit is the SP341 Smart Thermometer, which works with Type K probes to deliver reliable temperature readings from –50°C to 1350°C across pipes, surfaces, water and air. It uses Bluetooth connectivity to link to the subscription‑free TPI View app, allowing users to capture GPS‑tagged and date‑stamped measurements as they work.

Using the app makes reporting and auditing straightforward, enabling users to build single or multi‑point reports, manage jobs, and email all test results directly from site. This makes it easier to demonstrate compliance with Legionnaires’ control requirements and maintains clear, organised records for clients or facilities managers.

The kit includes a range of probes to cover typical Legionella checks. The CK21M pipe clamp probe measures pipe temperatures from –50°C to 250°C. It has a maximum clamping diameter of 30mm, a 1m lead, and durable polyurethane insulation, making it ideal for checking hot water flow and return lines.

Water temperatures in outlets, tanks or calorifiers ranging from –40°C to 850°C can be measured using the FK13M immersion probe, while the CK15M surface probe is suited to measuring higher temperatures from –40°C to 510°C on flat surfaces where direct contact readings are required. An air probe is also supplied for ambient temperature checks around plant rooms and outlets.

Everything is supplied in a durable zipper case to keep the instrument and probes protected and organised between jobs. The result is a complete, practical solution for temperature monitoring during Legionnaires’ risk assessments, combining trusted TPI measurement hardware with modern digital reporting to support consistent, professional work.
