The SK4TPHM1 kit has an onboard screen that gives technicians immediate access to critical system readings in the field without relying solely on a mobile device. Combined with wireless connectivity, the kit consolidates measurements, automatically calculates system comparisons, and organizes data into a single report for easier documentation and review, helping streamline diagnostics while supporting a more connected workflow, the press release said.

Dual psychrometers and manometers allow technicians to evaluate airflow, static pressure, and environmental conditions alongside refrigerant-side performance, helping deliver a more complete picture of system operation. Combined with the high- and low-side temperature clamps and pressure probes, the kit supports a comprehensive diagnostic approach that can help reduce callbacks, improve commissioning accuracy, and enhance overall system performance, the press release said.

“Today’s HVAC technicians need tools that do more than just provide measurements — they need solutions that help simplify diagnostics, improve accuracy, and save valuable time in the field,” said Keith Keller, NAVAC’s vice president of HVAC. “NAVAC continues to expand its smart tool ecosystem with products like the SK4TPHM1 kit, which are designed to simplify field workflows while maintaining the durability and performance HVAC professionals expect in demanding jobsite environments.”
