High accuracy hand-held thermometer

Maintenance and awareness are the first lines of defence in the battle against legionella.

Supporting operators in this battle, the Hanna HI-935005 delivers highly accurate temperature measurements across a wide range using a K-type thermocouple probe.

Display showing minimum and maximum temperature values taken during the measuring session helps with comprehensive record taking.

Used regularly in applications where warm or hot water is converted into droplet or steam formation, the high accuracy HI-935005 can help to prevent the risk of Legionella by ensuring that temperatures are high enough in the water system to destroy the bacteria.

Ideal for

  • Hospitals
  • Schools and colleges
  • Residential and care homes
  • Civic centres and leisure centres
  • Swimming pools and aquariums
  • Cooling towers
  • Breweries

Product uses

  • Used to test pipe surface or water temperatures, the HI 935005 is well-placed to head off Legionella concerns for a wide variety of industrial and leisure industries.
  • Air and water handling systems
  • Pipe surface temperatures
  • Water temperature from sentinel taps
  • Beer mash tanks

Key features

  • Water resistant casing
  • Large LCD display gives clear readings for current temperature plus min and max temp values since startup
  • Rubberised buttons are clearly marked for ease of use
  • Easy shift between °C and °F
  • HOLD to freeze readings on display and give more time to record data
  • CLEAR button restarts evaluation of high and low values
  • Equipped with Battery Error Prevention System to alert user if low battery is likely to adversely affect readings

Supplied with

  • Batteries
  • Instructions

Proactive management of water systems provides best protection against the spread of legionella bacteria.

Legionella bacteria is spread by water droplet contamination. It is therefore virtually impossible to guarantee that the bacteria will not exist in a water system. But by adopting a rigorous, proactive approach with routine controls, the risk of an outbreak can be minimised.

K-type Connection – Industry standard K-type Thermocouple connector. Can be used with any HANNA K-type thermocouple thermometer.
