Designed for solar power technicians, renewable energy specialists, and industrial electricians, the UT197PV combines specialized measurement capabilities with comprehensive durability features for accurate diagnostics in demanding field environments.
 
The UNI-T UT197PV is specifically designed to meet the unique measurement needs of solar installations and renewable energy systems. With DC voltage measurement up to 2500V and AC voltage up to 1500V, it provides the extended range necessary for modern solar arrays, large-scale installations, and high-voltage systems. This capability is essential for technicians working with both residential solar systems and commercial installations where standard multimeters often fall short.
The built-in power analysis functions enable comprehensive evaluation of system performance, including active power (W), apparent power (VA), reactive power (VAr), and power factor measurements. These capabilities allow technicians to verify system efficiency, diagnose power quality issues, and ensure optimal operation of inverters and control systems. With measurement ranges up to 2500kVA DC and 1500kVA AC, the UT197PV delivers the specialized functionality needed for complete solar system diagnostics.

This comprehensive measurement suite makes the UT197PV the ideal tool for solar power professionals who need complete diagnostic capabilities in a single instrument.
 
Extreme Environmental Durability
Solar installations exist in some of the most challenging environmental conditions, and the UT197PV is built to withstand these extremes:
IP67 rated for complete protection against dust ingress and water immersion
Verified 5-meter (16.4 ft) drop resistance for extreme mechanical shock protection
Operational temperature range of -40°C to 55°C (-40°F to 131°F) for desert to arctic environments
12kV pulse impulse protection against electrical surges
Mis-plug alarm to prevent incorrect terminal connections
Rugged overmolded case for secure grip in all conditions
These durability features ensure the meter performs reliably in challenging field environments including rooftop installations, desert solar farms, offshore wind facilities, and industrial power applications where environmental conditions would damage standard instruments.
 
Smart Connectivity and Data Logging
The integrated Bluetooth connectivity pairs with the UNI-T Smart Measure mobile application (available for both iOS and Android), allowing technicians to:
Record measurement data remotely for trend analysis and system monitoring
Generate real-time measurement charts for performance evaluation
Create professional testing reports for clients and documentation
Export data in multiple formats (PDF/XLS/JPEG/CSV)
Document system performance over time for maintenance records
This connectivity transforms the UT197PV from a simple measurement tool into a complete diagnostic system, enabling technicians to document solar system performance, share findings with team members, and maintain comprehensive installation records.
