Elcometer 319: The Comprehensive Practical Guide to Climate Data Management
Professional coating work requires perfect conditions. The Elcometer 319 Dewpoint Meter measures not only the critical dew point, but all climatic parameters needed for correct surface preparation and application. This guide shows you how to efficiently integrate the device into your workflow, avoid common mistakes, and fully utilize its performance.
Product Overview: Models and Core Functions
The robust Elcometer 319 is available in two versions, which differ mainly in their data collection functionality. Both are IP66 dust- and waterproof and provide precise measurements according to ISO 8502-4.
| Function | Model S | Model T* |
|---|---|---|
| Manual data storage | ✔ | ✔ |
| Automatic interval logging | – | ✔ |
| Bluetooth® data export | – | ✔ |
| Memory (up to 999 batches) | – | 25,000 records |
| Integrated magnets | ✔ | ✔ |
* According to manufacturer information. Technical data may change.
All-in-One Measurement
Measures 9 parameters: air & surface temperature, rel. humidity, dew point, TΔ, wet-bulb temperature and more.
Robust & Reliable
IP66 protection, usable from -20°C to +80°C. Integrated magnets for hands-free work on steel.
Easy Documentation
Model T: Transfer data via USB/Bluetooth® to ElcoMaster® and create reports with one click.
Do not only monitor the dew point, but also the difference between surface temperature (Ts) and dew point temperature (Td) – the TΔ. According to many manufacturer specifications, this should be at least 3°C. Set a lower alarm limit for TΔ in the Elcometer 319 to receive acoustic and visual warnings when conditions become critical.

Go to the Elcometer 319 in the shopRecommended Basic Settings (Guideline Values)
Configure your Elcometer 319 for typical coating applications as follows. These values are starting points – always check the specification of the material being used.
- Alarm limits: TΔ (Ts - Td) ≤ 3°C | Relative humidity ≥ 85% | Surface temperature outside material range.
- Logging interval (Model T): 5–15 minutes for long-term monitoring. Shorter intervals during rapid weather changes.
- Display: Select the 5 most important parameters (e.g. Ta, Ts, Td, TΔ, rH).
- Unit: Set to °C or °F according to project requirements.
Professional Workflow in 7 Steps
- Preparation: Check batteries (or USB power), connect external K-type probe if needed.
- Device placement: For remote logging, attach to the steel surface via magnets. Do not expose the sensor to direct sunlight or splashing water.
- Set parameters & alarms: Define project-specific limits in the menu.
- Start measurement: On Model T, start a logging batch and set the interval. For single readings, save manually.
- Monitoring: Continuously monitor display and audible alarms.
- Documentation: Transfer Model T data via Bluetooth® or USB to a mobile device/PC.
- Report creation: Generate automated inspection reports in ElcoMaster® and send them.
Troubleshooting: Common Issues & Solutions
1. Inaccurate Surface Temperature (Ts)
- Check the contact of the internal/external probe. Surface must be clean.
- Use the external magnetic probe (accessory) for more precise readings.
2. High Humidity Deviation
- Protect sensor from condensation. Do not move the device from very cold to warm environments quickly.
- Accuracy of ±3% rH applies at approx. 1 m/s airflow.
3. Device reacts slowly / does not start
- Replace batteries or use USB power.
- Observe operating temperature range (-20°C to +80°C).
4. Bluetooth® connection failed
- Ensure you are using the Model T.
- Keep app and device firmware up to date.
Maintenance & Calibration
- Clean the sensor area with a soft, dry cloth after use.
- For long-term storage: remove batteries.
- Do not expose the device to temperatures below -20°C or above +80°C.
- An annual recalibration at an Elcometer Authorized Service Centre is recommended to ensure measurement accuracy according to the certificate.
- Register your device online within 60 days to benefit from the free warranty extension from 1 to 2 years.
FAQ – Frequently Asked Questions about the Elcometer 319
1. Which model do I need – S or T?
Model S is ideal for manual single measurements and on-site checks. Model T is required if you need unattended long-term logging, automatic reports, or wireless data transfer.
2. Which standards does the device meet?
The Elcometer 319 complies with ISO 8502-4, BS 7079-B4, IMO MSC 215(82), and US Navy NSI 009-32, making it suitable for marine, industrial, and heritage coating projects.
3. How long does the battery last?
In manual mode (without backlight) over 40 hours. In logging mode (1 reading / 10 minutes) up to 400 hours. Continuous power supply via USB is also possible.
4. Can I measure liquid temperatures?
Yes, with an optional external liquid temperature probe (T9996390-, range: -200 to +1100°C) in Te mode. Ideal for checking material temperature before application.
5. Is the device really waterproof?
Yes, with IP66 protection it is resistant to high-pressure water jets and dust. The sensors are fully sealed. However, it is not designed for continuous immersion.
Conclusion
The Elcometer 319 Dewpoint Meter is more than just a dew point gauge – it is a complete climate data management system for professional coating practice. With its robustness, comprehensive parameter measurement, and seamless documentation capability (especially the Model T), it reduces the risk of application errors and provides audit-safe proof of perfect climatic conditions. Investing in the right model for your application pays off in quality and efficiency.
