NAVAC has launched the SK4TPHM1 Smart Refrigerant & Air Side Diagnostics Pro Kit, a wireless diagnostic kit for HVAC/R technicians that pairs with both the myNAVAC app and the MeasureQuick app, according to a July 3, 2026 report from HVAC/P. The kit expands NAVAC's smart diagnostics portfolio with a bundled set of wireless sensors built to capture refrigerant-side and air-side readings during system commissioning and service work.

NAVAC positions the kit as a way to reduce callbacks and improve commissioning accuracy by giving technicians a single, wireless toolset that reads both refrigerant pressures and temperatures alongside air-side conditions, rather than relying on separate handheld instruments for each measurement.

Smart Refrigerant & Air Side Diagnostics Pro Kit Components

The SK4TPHM1 kit includes NST1 and NST2 high- and low-side temperature clamps, two NSP1 pressure probes, two NSH1 psychrometers, two NSM1 manometers, and two F1030 quarter-inch access tees, according to HVAC/P's report. Together, the components are designed to let a technician measure refrigerant pressures and temperatures on both the high and low sides of a system, along with wet-bulb and dry-bulb air conditions and static pressure, from a single kit.

Pressure probes and temperature clamps are standard tools used to determine superheat and subcooling values during refrigerant charging, while psychrometers and manometers are used to evaluate air-side performance, such as airflow and duct static pressure, across an HVAC system. The F1030 access tees are quarter-inch fittings used to connect gauges or probes to a refrigerant line for readings.

Wireless refrigerant probes and clamps of this type typically attach to a system's service valves or line sets and transmit pressure and temperature readings to a receiving device over a wireless connection, removing the need for hoses or wired sensor leads between the equipment and a technician's phone or tablet. Bundling that hardware into one kit, along with air-side instruments such as psychrometers and manometers, is intended to let a single technician complete both refrigerant-side and air-side checks during one visit rather than carrying separate tool sets for each type of measurement.

Onboard Screen and App Connectivity

The kit features an onboard screen that lets technicians view field readings directly without needing to look at a separate mobile device, HVAC/P reported. That onboard display works alongside the kit's compatibility with both the myNAVAC app and the MeasureQuick app, giving technicians a choice of software platforms for logging, analyzing, or sharing diagnostic data collected in the field.

MeasureQuick is a third-party diagnostic app widely used across the HVAC/R trade for guided system diagnostics, while myNAVAC is NAVAC's own app for its line of tools and gauges. By supporting both platforms, the SK4TPHM1 kit is designed to work within a technician's existing workflow rather than requiring a switch to a single proprietary system.

Industry Context

Wireless refrigerant and air-side diagnostic tools have become more common across the HVAC/R trade as manufacturers look to cut down on measurement error and rework tied to improper refrigerant charging and airflow setup. Superheat and subcooling readings, taken from pressure and temperature at the high and low sides of a system, are standard checks used during startup and commissioning to confirm a system is charged correctly. Errors in those readings, or in air-side measurements such as static pressure and wet-bulb temperature, are commonly cited causes of comfort complaints and return trips in the field.

NAVAC's framing of the SK4TPHM1 Smart Refrigerant & Air Side Diagnostics Pro Kit as a callback-reduction and commissioning-accuracy tool reflects that broader dynamic in the trade, where labor costs and truck-roll expenses have pushed manufacturers toward combined, app-connected instruments in place of single-purpose analog gauges.

Commissioning errors and undiagnosed airflow or charge problems are frequently cited in the trade as contributors to compressor failures, reduced equipment life and comfort complaints that generate return visits. Manufacturers of test instruments have increasingly added wireless connectivity and companion apps to their product lines over the past several years, allowing technicians to log and store readings digitally rather than recording them by hand, and to reference stored data during callbacks or warranty claims.

Availability of the Smart Refrigerant & Air Side Diagnostics Pro Kit

HVAC/P's July 3 report did not include pricing or a specific release date for the SK4TPHM1 Smart Refrigerant & Air Side Diagnostics Pro Kit. The kit is being positioned within NAVAC's broader smart diagnostics lineup, which centers on wireless, app-connected instruments as an alternative to standalone analog gauges and meters.
