Description

At Fieldpiece, we started with the idea that every HVACR professional in the field needs the best tools possible. It’s a simple premise, and one that we’ve held tightly to as we’ve grown into a best-in-class innovator of industry-leading tools for HVACR pros over the last 30+ years. Fieldpiece is laser-focused on creating products that empower HVACR professionals - today and tomorrow. Representing the latest advances in technology, our air kits deliver lightning-fast readings in real-time to your Job Link System App. Designed and built to be tough, accurate and exactly what a pro in the field needs. After all, that’s what Fieldpiece is all about. This kit consists of 2 pressure probes, 2 pipe clamps, and 2 psychrometers in a quick access padded case. All measurements can be sent up to 1000’ away directly to your mobile device with the Job Link System mobile app. Designed for agility and speed, the pressure probes fit into tight spaces and the pipe clamps use the new Rapid Rail sensor design delivering accuracy, every time, even on the most awkward pipe configurations. Improve professionalism and increase efficiency with the Job Link App. Easily manage jobs, connect to tools and get diagnostics while on the job site. The app allows you to generate reports, reducing callbacks and allows you to work in multiple locations at one time. Learn more in this video about how you can enhance work processes and enhance your overall jobsite experience. JL3KH6 SM482V MR45 VP87 DR82 MG44 SR47

Best purchase ever.
This is better than having an actual manifold. You will have to get a 3 port adapter to add freon but the Bluetooth up to 1000ft is absolutely amazing. It's so easy to set up and links to the app every time you log on. There so much you can do with this set and I've barely even scared the surface! I use it every day on split systems and package units. And when I'm vacuuming I can sit in my van when it's 110° outside and watch it pump down from there. ... show more

Bad shipping
Product is great. Shipping was absolutely horrible. Came almost a week late from original prime order.

Essential HVAC Kit
Do you enjoy lugging around a giant gauge set and losing precious ounces of Freon every time you hook up to a maintenance customer’s AC to check the charge? Neither do I. This kit doesn’t even need low loss fittings. They somehow made it so you screw it in and the moment it presses on the Schrader it seals perfectly. Links to the phone so you can walk around and do other stuff while you wait for the AC to stabilize. This kit does everything short of filling out the invoice for you and collecting payment. I pitty the fool who doesn’t get themselves this totally sweet charge kit! You can collect your SH/SC, pressures, and delta T all onto your phone with performance graphs to show your customer the health of their system and document the job in your CRM. I mean c’mon, guy! This is the ultimate upgrade to your service kit. I love using it every day and those bent condenser fins where you used to hang your gauge set also love it. ... show more

I used it for a year and I am very satisfied.
I've been using these tools almost every day for over a year, and they've never let me down. It is very convenient to use when you need to prevent the loss of freon from the system.
