Product Overview
The Testo 0628 0020 Temperature Probe with Velcro is a precision contact sensor designed for reliable temperature measurement in industrial pipe systems. It features a robust K-type thermocouple (TC Type K), an extended operating range of -50 °C to +120 °C, and a convenient Velcro strap** that allows quick attachment and removal from piping surfaces.
Key Features
- Class 1 Accuracy: Ensures high precision for critical process monitoring.
- Wide Temperature Range: From deep sub‑freezing to moderate heating environments.
- Durable Construction: Stainless steel housing protects the thermocouple from mechanical stress and corrosion.
- Velcro Attachment: Flexible, reusable strap for fast installation on various pipe diameters without the need for clamps or brackets.
- Long Probe Length (395 mm): Provides ample reach to contact points that are difficult to access.
- Easy Cable Management: The cable is pre‑terminated with a standard connector, simplifying integration into existing measurement systems.

Installation Guide
- Preparation: Clean the pipe surface where the probe will be mounted. Remove oil, grease, and debris to ensure optimal thermal contact.
- Positioning: Slide the probe onto the pipe until it reaches the desired measurement point. The Velcro strap should be positioned around the pipe circumference.
- Securing**: Tighten the Velcro strap by pulling the ends together and fastening them with the provided hook or clip. Ensure a snug fit to maintain consistent contact pressure.
- Cable Routing**: Route the cable along the pipe, avoiding sharp bends that could damage the conductor. Use cable ties if necessary for neatness.
- Connection**: Attach the probe’s connector to the measurement instrument or data acquisition system following standard wiring procedures.
Maintenance & Care
- Inspect the Velcro strap periodically; replace if adhesive loses tackiness.
- Check for corrosion on the stainless steel housing, especially in harsh chemical environments. Clean with a mild detergent and dry thoroughly.
- Verify cable integrity by inspecting for fraying or cuts. Replace damaged sections immediately to avoid measurement errors.
- Recalibrate the probe as per the manufacturer’s calibration schedule to maintain Class 1 accuracy.
Applications
The Testo 0628 0020 is ideal for:
- Process Control: Monitoring temperature in chemical reactors, heat exchangers, and distillation columns.
- HVAC Systems: Measuring air or fluid temperatures within ductwork and piping.
- Food & Beverage Industry: Tracking temperature during cooking, cooling, and storage processes.
- Petrochemical Plants: Ensuring safe operating conditions in pipelines carrying hydrocarbons.
- Automotive Manufacturing: Monitoring temperatures in assembly lines and component testing rigs.
Benefits of Velcro Attachment
- Rapid Deployment**: Install or remove the probe within seconds, reducing downtime during maintenance or reconfiguration.
- Versatility**: Works on a wide range of pipe diameters and materials without requiring additional hardware.
- Reusability**: The Velcro strap can be reused multiple times, providing cost savings over fixed mounting solutions.
- Minimal Mechanical Stress**: Unlike clamps that may deform the pipe, the Velcro system distributes pressure evenly.
Compatibility & Integration
The probe’s standard K‑type connector is compatible with most industrial data loggers, PLCs, and SCADA systems. It can be integrated into:
- Temperature Monitoring Panels: Directly wired to analog or digital input modules.
- Remote Sensing Networks: Connected via wireless gateways for real‑time data transmission.
- Calibration Stations: Used as a reference sensor during calibration of other temperature measurement devices.
Performance Highlights
- Fast response time due to the thin thermocouple wire and direct contact with the pipe surface.
- High stability over long periods, thanks to the corrosion‑resistant stainless steel housing.
- Low drift characteristics typical of K‑type thermocouples, ensuring reliable readings across the entire temperature range.
Frequently Asked Questions
- What is the maximum pipe diameter that can be used with this probe?
- The Velcro strap accommodates pipes from approximately 20 mm to 150 mm in outer diameter, depending on strap width and tension.
- Can the probe be used in corrosive environments?
- Yes, the stainless steel housing resists most industrial chemicals. For highly aggressive media, consider additional protective coatings or a dedicated chemical‑resistant enclosure.
- How often should I recalibrate the probe?
- For Class 1 accuracy, a yearly calibration is recommended, but this may vary based on process criticality and regulatory requirements.
- Is the Velcro strap reusable after multiple uses?
- The strap retains its adhesive properties for many cycles; however, replace it if you notice any loss of tension or stickiness.
Conclusion
The Testo 0628 0020 Temperature Probe with Velcro combines precision measurement**, **robust construction**, and **user‑friendly mounting** into a single solution. Its Class 1 accuracy, wide temperature range, and flexible attachment make it an excellent choice for demanding industrial applications where reliable temperature data is essential.
