About this product

The Elcometer 319 Dewpoint Meter with Bluetooth (part numbers G319-S and G319-T) measures and records all the climatic parameters needed to determine whether conditions are suitable for painting.

If climatic conditions are wrong when a coating is applied, the coating can fail in service, so monitoring them before and during application protects the work. The Elcometer 319 reads relative humidity, air temperature, surface temperature, dewpoint, the Delta T (the difference between surface temperature and dewpoint), dry bulb and wet bulb temperatures, an external K-type temperature and specific humidity. It can be used as a hand-held meter or, with its integral magnets holding it to a substrate, as a remote data logging monitor. High and low limits can be set against any or all parameters to trigger audible, visual and red or green LED alarms, which is useful in paint booths. A magnetic surface temperature probe allows surface temperature to be logged remotely, and a liquid temperature probe turns the gauge into a thermometer for checking paint temperature before application.

The Elcometer 319 Dewpoint Meter with Bluetooth reads air, surface and gauge temperatures from -20 to +80 degrees C to plus or minus 0.5 degrees C at 0.1 degrees C resolution, an external K-type thermocouple from -40 to +200 degrees C, and relative humidity from 0 to 100% RH to plus or minus 3% RH. The body is dustproof and waterproof with fully sealed sensors, rated equivalent to IP66, and it runs on two AA batteries for up to 400 hours or via USB. Two models are offered: Model S stores the last 10 records, while Model T stores 25,000 records in up to 999 batches, adds interval logging adjustable between 1 second and 1 hour, and outputs via USB or Bluetooth to a computer, Android and iOS device for evaluation in ElcoMaster software. A calibration certificate is supplied as standard.

The Elcometer 319 can be used in accordance with BS 7079-B4, IMO MSC.215(82), IMO MSC.244(83), ISO 8502-4, US Navy NSI 009-32 and US Navy PPI 63101-000, the recognised standards for climatic monitoring and surface condensation assessment. It is used by coatings inspectors in marine, offshore, protective coating and shipbuilding work, and is supplied by BAMR, South Africa's authorised Elcometer distributor.

Decision guide

When to use the Elcometer 319 Dewpoint Meter

Use the Elcometer 319 when you need to record every climatic parameter that decides whether a surface is fit to paint, and keep an auditable log of it. It measures air, surface and dewpoint temperatures, relative humidity and more, with each reading time and date stamped to ISO 8502-4.

  • 1
    Logs the full climatic set
    It records RH, air, surface, dewpoint, wet and dry bulb and surface temperature difference, so a single instrument covers the whole pre-paint check.
  • 2
    Large traceable memory
    The Model T stores 25,000 records in up to 999 batches with a supplied calibration certificate, which is what underpins a defensible inspection record.
  • 3
    Hand-held or remote logging
    It works in your hand or as a remote data logger with a magnetic surface probe, so you can leave it monitoring conditions during a coating job.
  • 4
    Download by USB or Bluetooth
    Data transfers to ElcoMaster on PC, Android or iOS, so reports come straight off the gauge rather than being copied by hand.

Answers

Frequently asked questions

Why is dewpoint important before painting?

The 319 measures the climatic parameters needed to determine whether conditions are suitable for painting. Relative humidity and substrate temperature directly affect coating adhesion and curing, so checking them before application prevents defects.

What is the difference between the Model S and Model T?

Model S records the last 10 readings only. Model T stores 25,000 readings across 999 batches, logs data automatically at intervals from 1 second to 24 hours, and transmits data via Bluetooth to computers and mobile devices or via USB with ElcoMaster software.

Can the 319 measure the surface temperature of what I am about to coat?

Yes. The built-in Ts sensor measures surface temperature from -20 to +80°C with ±0.5°C accuracy. For higher temperatures, connect an optional K-Type thermocouple, which measures up to +200°C.

Does the Model T connect to my phone or computer?

Yes. Model T has Bluetooth connectivity to computer, Android, and iOS devices. A USB cable and ElcoMaster software are also supplied for data transfer and analysis.

How long do the batteries last?

In manual mode with backlight off, battery life exceeds 40 hours. When interval logging is enabled, battery life extends to up to 400 hours at a logging interval of 1 reading every 10 minutes. The 319 uses two AA 1.5V batteries or can be powered via USB cable.
