TPI SP341LK Legionella Temperature Test Kit

The TPI SP341LK Legionella Temperature Test Kit provides a portable method for checking water system temperatures during routine legionella monitoring. It connects to a smartphone or tablet through Bluetooth 4.2 and sends live temperature readings to the mobile application. Test results can also be stored within the app and grouped by site location, helping users keep organised temperature records.

Supplied immersion and surface probes allow the kit to handle both water and contact temperature checks. Slim probe construction helps users reach taps, tanks and pipework outlets where access may be limited. The instrument also supports single and differential temperature measurement, giving the user more than one way to assess temperatures during site work.

The TPI SP341LK Legionella Temperature Test Kit accepts Type K thermocouples fitted with sub-mini connectors and provides an instrument range from -50°C to 1350°C. A field calibration function supports measurement confidence, while a flashing red LED provides a clear low battery indication. Three AAA batteries provide approximately 75 hours of operating time, and the supplied A926 zipper carry case keeps the thermometer and probes together for transport.

Key Benefits
  • Supports routine legionella compliance temperature checks with a compact handheld kit.
  • Bluetooth 4.2 allows live readings to be viewed on a smartphone or tablet.
  • Mobile app storage keeps test results organised by site location for clearer records.
  • Single and differential modes provide flexibility for different temperature checks.
  • Immersion and surface probes allow both water and contact temperature measurement.
  • Slim probes help users gain access to taps, tanks and pipework outlets in confined areas.
  • Field calibration provides added measurement confidence during regular site testing.
  • A flashing red LED makes low battery condition easy to identify during use.
  • Approximately 75 hours of battery life supports extended field testing between battery changes.
  • The supplied zipper carry case keeps the main instrument and probes together between jobs.
Common Applications

TPI SP341LK Legionella Temperature Test Kit is suitable for a range of testing, maintenance and inspection tasks, including:

  • Routine legionella temperature compliance checks
  • Water temperature measurement with the immersion probe
  • Surface temperature measurement with the surface probe
  • Temperature checks at taps
  • Temperature checks on tanks
  • Temperature checks on pipework outlets
  • Single temperature measurement
  • Differential temperature measurement
  • Recording test results by site location
Why Choose This Model?

This model combines Bluetooth app-based recording with both immersion and surface probes in one supplied kit. No alternative product models are identified in the supplied information, so no unsupported model-to-model differences have been added.
