The Fieldpiece JL3KH6 Job Link Probes Charge and Air Kit allows you to take a complete system snapshot quickly and easily. This Fieldpiece Wireless Probes kit consists of 2 pressure probes, two pipe clamps, and two psychrometers in a quick-access padded case. Also, measurements will be sent up to 1000’ directly to your mobile device. You will do so with the Job Link® System mobile app.  Each tool was designed for agility and speed.

The pressure probes fit into tight spaces. Furthermore, the pipe clamps use the new Rapid Rail thermocouple sensor design. Doing so delivers accuracy, speed, and agility, even on the most awkward pipe configurations. The psychrometers’ flexible narrow probes and configurable magnet make it easy to measure supply plenums, ducts, and high registers. All inquiries are expandable for multi-circuit systems.

The Fieldpiece JL3KH6 Job Link Wireless Probes Charge and Air Kit bring HVAC diagnostics into the 21st century. Analyze AC systems much faster with this set of intelligent probes. Also, each quest has an estimated wireless range of 1000 feet. You can couple it with the Job Link app on your mobile device to view each measurement live.

The Job Link HVAC Kit was designed giving HVAC technicians more freedom. Moreover, we are improving productivity while on the job site. Each kit includes six wireless probes: 2 pressure, two psychrometer, and two pipe clamps.

The Fieldpiece Job Link Pressure Probes was designed to fit tight spaces. Also, featuring an angled 1/4″ fitting. At the bottom of each unit is a switch that toggles between Blue (Low Side) and Red (High Side). This is an excellent feature because it communicates with the Job Link app and shows up when viewing the measurements.

The Fieldpiece Job Link Flex Psychrometer Probes measure %RH, dry/wet bulb, dew point, and enthalpy and feature a strong magnet. Moreover, the flexible probe and sliding magnet allows you to configure the probe. They will be used even when space is limited. Also, like the JL3PR Pressure probes, these probes feature a switch on the bottom. Also used to toggle between blue and red. They are distinguishing between Supply Air and Return Air.

The JL3PC Job Link Premium Pipe Clamp Probes take fast and accurate temperature measurements surpass California’s Title 24 requirements. These clamps will be used on pipes that range from 1/4″ up to 1-3/8″. This information will get etched on the side of the clamp to reference quickly in the field.

Also, these pipe clamps utilize the patent-pending Rapid Rail sensor technology that requires electrical continuity to complete the circuit. Doing this improves accuracy by reducing ambient conditions’ effect on the measurements. Furthermore, this also allows the temperature readings to stabilize in under 5 seconds.

The new intelligent Fieldpiece probe kit is an excellent addition to any HVAC technician’s tool bag by giving a live view of the system’s work quickly and effectively. Do more with Job Link probes today!
