Elcometer 319 Dewpoint Meter

dewpoint meter

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 remote data monitoring on steel substrates
  • Store 25,000 records in up to 999 batches
  • USB and Bluetooth data output to a PC or PDA
  • Dustproof and waterproof gauge with fully sealed sensors (equivalent to IP66)
  • Visual and audible indication of user defined limits against any or all parameters
  • Easy to use, intuitive multi-lingual menu structure
  • A hand-held Dewpoint meter with manual and interval data logging in one gauge
  • Large, customer definable illuminated display operates over the full temperature range
  • 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


  • Meets ISO 8502-4
  • Rapid response time
  • Each instrument is supplied with a Calibration Certificate
  • Readings are switchable between Celsius and Fahrenheit
  • Time and date stamp is recorded for each set of readings
  • Easy menu-driven interface in multiple languages
  • Clear, illuminated display showing up to five parameters from:
    RH: % Relative Humidity
    Ts: Surface Temperature
    Ta: Ambient Air Temperature
    Td: Dewpoint Temperature
    TΔ: the difference between the Td and Ts
    Tdb: Dry Bulb Temperature
    Twb: Wet Bulb Temperature
    SH: Specific Humidity 
  • 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
  • Selecting the "Te" mode transforms the gauge into a simple thermometer - ideal for measuring a coating's temperature prior to application or other external temperatures (Te)
  • Hold/freeze function allows manual readings to be taken and reviewed before being logged into memory


  • Manufactured from temperature resistant materials ensuring safe use in climates ranging between -20°C (-4°F) and +80°C (+176°F)
  • Waterproof and dust proof rating equivalent to IP66
  • The rugged and ergonomic design extends to include durable industrial sensors ideal for harsh environments
  • The instrument's clear illuminated display operates over its full temperature range


  • Data can be downloaded to a PC via USB or Bluetooth and evaluated using ElcoMaster 2.0 Software
  • ElcoMaster Software supplied with unique "Watchguard" functionality allowing the user to remotely monitor up to 42 gauges on one screen*
  • 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 triggers visual and audible alarms whenever a limit is exceeded - even if it is not displayed on the screen
