Product Description

This rugged gauge is designed to measure and record all relevant climatic parameters required to determine whether the conditions are suitable for painting. The Elcometer 319 can be used as a hand-held gauge or a stand alone data logger - ideal for monitoring climatic conditions over a period of time.

  • Integrated magnets allow the gauge to be attached to the substrate during remote logging

  • Stores 25,000 records in up to 999 batches

  • Dustproof and waterproof gauge with fully sealed sensors (equivalent to IP66)

  • Gauges can be recertified at Elcometer Authorised Service Centres

  • Robust temperature sensors

  • Easy to use, intuitive menu structure

  • Measure and record climatic parameters:
    Relative humidity
    Air temperature
    Surface temperature
    Dewpoint temperature
    TΔ (the difference between
    surface temperature and dewpoint)
    Dry Bulb temperature
    Wet Bulb temperature
    External temperature correction (K-type)
    Specific Humidity

  • Visual and audible indication of user defined limits for any or all parameters

  • USB and Bluetooth® data output to ElcoMaster™ software

  • Meets ISO 8502-4
  • Each instrument is supplied with a Calibration Certificate
  • Readings are switchable between Celsius and Fahrenheit
  • All readings are time & date stamped


  • Easy menu-driven user interface in multiple languages
  • Clear, illuminated display showing up to five user-defined parameters
  • Arrow indicators show temperature trends


  • The gauge can be used as either a hand-held Dewpoint meter or as a remote data logging monitor

  • Integrated K-Type connector allows measurement of surface temperature during remote logging using a remote probe

  • Using an external probe the “Te” mode transforms the gauge into a thermometer - ideal for measuring temperature of a paint prior to application

  • Hold/freeze function allows manual readings to be reviewed before being added into the memory


  • Safe use in climates ranging between 
  • -20°C (-4°F) and +80°C (+176°F)
  • Waterproof and dust proof rating equivalent to IP66
  • Rugged and ergonomic design, re-engineered sensors have greater durability for an extended life


  • Rapid response time
  • Data can be downloaded to a PC via USB or Bluetooth® and evaluated using ElcoMaster™ Software
  • Each gauge can be powered by either 2 AA batteries (for up to 400 hours# use) or directly via the USB cable
  • Adjustable limits can be set for each measurement parameter which trigger visual and audible alarms whenever a limit is exceeded
  • Intelligent memory calculates total available logging time when using batches
  • Gauges can be recertified at Elcometer Authorised Service Centres
