In protective coating applications, monitoring environmental conditions before, during, and after the coating process is critical to ensure the durability of the coated surface. To prevent condensation and coating failure, the surface temperature should be at least 3 °C (5 °F) higher than the dew point.
Why Environmental Monitoring Matters
Condensation on freshly prepared steel surfaces is often invisible but can lead to rust if not detected early. The PosiTector DPM helps users assess the risk of moisture forming on such surfaces. If moisture becomes trapped between the coating and the surface, it can cause long-term failure.
By measuring the dew point and comparing it to the surface temperature, users can determine if conditions are safe for coating. Low temperatures and high humidity can also prevent coatings from drying and curing properly. Monitoring after application ensures optimal conditions for the coating to cure fully.

Remote Environmental Monitoring
Remote environmental monitoring is essential, especially in industrial applications like protective coatings, due to several key reasons:
1. Prevents Coating Failures
If temperature and humidity are not properly controlled, condensation can form on metal surfaces—often invisible to the eye. This moisture can:
- Cause flash rusting on uncoated steel.
- Weaken the bond between the coating and the surface, leading to premature failure like peeling or cracking.
2. Ensures Ideal Conditions for Coating Application
Many coatings won’t dry or cure properly if: The temperature is too low, or relative humidity is too high. With remote monitoring, you can ensure environmental conditions remain within the recommended range—without needing to be physically present on-site.
3. Saves Time and Costs
- Eliminates the need for constant manual inspection.
- Enables monitoring of multiple sites simultaneously from a single dashboard.
- Sends real-time alerts when conditions go out of range, allowing for quicker response and preventing costly damage or rework.
4. Automated Data Logging and Documentation
Remote monitoring tools automatically record environmental data, which is useful for:
- Quality audits or certifications.
- Reporting to clients or project managers.
- Analyzing trends over time to improve future planning.
5. Improves System Reliability and Safety
Continuous monitoring helps:
- Maintain equipment performance and system stability.
- Avoid unnecessary maintenance or shutdowns, since real-time data shows whether systems are operating under safe conditions.
Remote Monitoring with PosiTector DPM and PosiSoft.net
The Auto Logging and Remote Monitoring features of the PosiTector DPM allow users to view environmental data from multiple locations in real-time using PosiSoft.net from any web browser. PosiTector Advanced users can also:
- Upload data to an FTP server via WiFi.
- Receive email alerts when environmental conditions exceed specified limits.
How to Enable Remote Monitoring
Step 1: Connect PosiTector DPM Advanced to WiFi
- Go to Menu > Connect > WiFi > Enabled.
- Select your network, enter the password, and press OK.
- Turn on Auto Sync .net for automatic cloud sync.
Benefits of a continuous WiFi connection:
- Automatic data backup to the cloud.
- Live remote viewing of measurements.
- Wireless firmware updates.
Step 2: Enable Auto Log Mode
PosiTector DPM Standard
- Logs data for up to 60 hours on battery, or continuously via USB.
- Enable via: Menu > Auto Log > Enabled, set the desired logging interval.
PosiTector DPM Advanced
- Enhanced mode extends battery life up to 8 months.
- Data can be uploaded to PosiSoft.net or an FTP server.
- Automatically groups data into daily, weekly, or monthly batches.
PosiTector DPM L (Logger)
- Switch the device ON by removing the top cover and sliding the power switch.
- Connect via PosiTector App or PosiTector Advanced gage.
- Start logging directly from the app.
Step 3: Configure Email Alarms (Optional)
Advanced models can send automatic email notifications when conditions exceed defined limits. WiFi is required, but Auto Log does not need to be enabled for this feature to work.
Step 4: Monitor in Real-Time via DPM Monitor
The new DPM Monitor feature in PosiSoft Desktop and PosiSoft.net lets users monitor multiple instruments remotely, anywhere in the world.
- PosiSoft Desktop: Powerful software for downloading, archiving, and generating reports.
-
PosiSoft.net: Secure cloud platform for real-time viewing of DPM data.
Share data with others via a secure public link without requiring a login.
Step 5: Create Professional PDF Reports
Use PosiSoft Desktop or the PosiTector App to create and share PDF reports:
- Add your logo, notes, images, and customize formatting.
- Export and share via email, Dropbox, or AirPrint.
Step 6: Transfer Data to an FTP File (Optional)
PosiTector DPM Advanced models can upload logged readings directly to an FTP server in .txt format (CSV). This is ideal for custom software or automated systems.
