The HD780 Digital Manifold/Pressure Gauge is an all-in-one tool that lets HVAC pros measure suction-line or liquid-line pressure and line temperature to instantly obtain superheat and subcooling values. It also calculates differential pressure (P1-P2) and delta-T (T1-T2).

The Yellow Jacket® Omni™ Digital Vacuum Gauge is easy-to-use, compact, rugged, and offers several features. Made with high-impact, glass reinforced housing, it survives moisture and accidental drops or attachment to a high pressure line. 

These gauges combine National Institute for Standards and Technology (NIST)-traceable pressure and high-accuracy temperature measurements.

This digital pressure and flow gauge includes five ports and connectors for USB, Ethernet, power, micro USB, and fan control.

This product is specifically designed for refrigerant applications. The oil circulation ratio in a refrigerant can be monitored online and directly in the process using sonic velocity measurement. 

The devices can then transmit those measurements to the Job Link System where they can be used to diagnose a system, be included on customer reports, and saved for reference on future calls. 

Connected to this system by LED Link, any LED fixture or retrofit kit can harvest intelligent building feedback. Lights can feel how warm or cold a room is, see if anyone is occupying the space and sniff out odors and potentially toxic chemicals in the air, including smoke, carbon monoxide, and harmful VOCs. 

This product exploits the latest advancements in polymer humidity sensing technology and compact electronic circuitry. It continuously measures up to four measurement parameters using a single intelligent sensor tip, including relative humidity, calculated dew point, temperature, and either absolute or barometric pressure. 

This monitor accurately measures from atmospheric level (20.94 percent) down to 100 parts per million (ppm), which accurately informs the welder when to commence welding.
