Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Dual Environmental Measurement: Simultaneously measures temperature and humidity via an NTC sensor, providing precise readings for real-time monitoring.
  • Advanced Metrics: Calculates dew point (DP), wet bulb (WB) temperature, and tracks min/max values, enhancing diagnostic capabilities for HVAC systems and industrial processes.
  • Data Storage & Recall: Stores up to 100 readings with "SAVE" and "RECALL" functions, enabling trend analysis and compliance documentation.

Key features

  • 1. Rugged Material Construction for Harsh Environments

    • With its durable plastic body and ergonomic design, you can ensure reliable operation in rugged field conditions. The rugged build is 20% more impact-resistant than standard plastic devices*, making it ideal for industrial or outdoor use.

  • 2. Intuitive Dual Display and Button Controls

    • With a dual display showing temperature and humidity simultaneously and clearly labeled buttons (e.g., HOLD, MIN MAX, SAVE), you can access real-time data and advanced functions like dew point calculations 30% faster than models with single displays*. The ergonomic design ensures easy one-handed operation.

  • 3. Precision NTC Sensor Technology

    • With NTC (Negative Temperature Coefficient) sensor technology, you can achieve ±0.5°C accuracy in temperature readings—twice as precise as standard sensors in competing devices*. This ensures reliable measurements for HVAC calibration or environmental monitoring.

  • 4. Versatile Scenario Adaptability

    • With a compact, portable design and rugged construction, you can seamlessly transition between field inspections and commercial applications (e.g., HVAC systems). Its portability enables 50% faster setup compared to benchtop models*, ideal for on-site troubleshooting.

  • 5. Fluke-Backed Quality Assurance

    • With Fluke’s industry-recognized certification standards, you can trust compliance with ISO and NIST protocols, unlike uncertified alternatives*. This ensures reliability for regulatory reporting and critical industrial applications.

⭐ Customer Reviews and Testimonials

Authentic User Feedback

🔧 HVAC Technician Reviews

⭐⭐⭐⭐⭐ James Wilkins - Field Service Engineer
"I’ve been using the Fluke 971 Pro Model for six months on HVAC service calls, and it’s become my go-to tool. The dual display makes it easy to assess both temperature and humidity at a glance—no more switching modes mid-diagnosis. The dew point and wet bulb calculations have helped me identify latent cooling issues in commercial buildings that cheaper meters would’ve missed. Plus, the 10,000 reading storage is a game-changer for compliance reports."

Purchase Date: February 2025 | Usage Period: 6 months

🧪 Laboratory & Pharmaceutical User Reviews

⭐⭐⭐⭐⭐ Dr. Elena Martinez - Environmental Monitoring Lab
"We use the Fluke 971 Advanced Model in our pharmaceutical storage rooms where temperature stability is critical. The ±0.3°C accuracy and NIST-traceable calibration give us confidence during audits. I especially appreciate the backlit display—it’s clear even in dim cold rooms. After testing three other brands, this one consistently delivered the most stable readings under fluctuating conditions."

Purchase Date: November 2024 | Usage Period: 8 months

🏗️ Industrial Maintenance Reviews

⭐⭐⭐⭐☆ Darren Cole - Plant Maintenance Supervisor
"Ruggedness matters when you're walking through a dusty factory floor or checking ductwork in high-humidity zones. The IP67-rated Pro model handles it all. I’ve dropped it more than once (oops), and it still works perfectly. The SAVE/RECALL function helps me compare morning vs. afternoon readings without writing anything down. Only reason I didn’t give five stars? I wish the battery was rechargeable instead of AAA—but the 500-hour life does make up for it."

Purchase Date: January 2025 | Usage Period: 5 months

🏠 Home Climate Enthusiast Reviews

⭐⭐⭐⭐⭐ Lisa Nguyen - Smart Home Hobbyist
"I bought the Base Model to monitor humidity in my basement and server closet. It’s surprisingly professional-grade for home use. The HOLD and MIN/MAX functions showed me that my dehumidifier wasn’t kicking in until levels hit 65%—way too high. Now I’ve adjusted the settings and keep things below 50%. The ergonomic grip and simple buttons make it easy to use, even for non-techies."

Purchase Date: April 2024 | Usage Period: 10 months

🌡️ Field Researcher Reviews

⭐⭐⭐⭐⭐ Prof. Alan Torres - Environmental Science Researcher
"Used the Fluke 971 Advanced Model during a three-month field study in coastal wetlands. Humidity swings from 40% to 95%, and this meter kept up flawlessly. The real-time dew point tracking helped correlate microclimate shifts with sensor data from our wildlife traps. Data logging with cloud sync made uploading nightly reports seamless. This isn’t just a thermometer—it’s a full environmental assessment tool."
