Review: From rookie to pro in one tool upgrade - This is a game changer for HVAC work. No more refrigerant losses when taking readings. No more trying to read the gage to get it roughly accurate. No more struggles to get reliable temp reading. Ability to readout values from a distance on an easy to read app. This pays for itself in time saved, refrigerant losses, accuracy and "Tool Pride"! Costs a lot but well worth it. My only negative is the apps available limit their features unless you subscribe to a service and I hate subscription scams. Still the basic free app that comes with is adequate for a hobbyist or part time HVAC guy and your company will buy the subscription if you work for a legit company. Review: A great tool - It connects directly to the air conditioning system's service port, minimizing the need for connecting hoses and excessive fittings, thereby reducing refrigerant leakage to a minimum. Furthermore, real-time measurement data can be read directly via a mobile app. This is an incredibly professional and efficient tool for HVAC contractors—it's fantastic! ## Features - Accurate at any elevation, directly transmits to mobile devices using job link app - Up to 350’ wireless signal - Stabilizes in under 5 seconds with +/-1° accuracy - Long flexible probe with sliding magnet for easy and precise hands-free testing ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0743SVJ9X | | Best Sellers Rank | #44,151 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #65 in Multi Testers | | Brand | Fieldpiece | | Brand Name | Fieldpiece | | Color | Yellow | | Compatible Devices | Mobile devices with 'job link app', Bluetooth-enabled devices | | Customer Reviews | 4.7 out of 5 stars 527 Reviews | | Global Trade Identification Number | 00872641003395 | | Included Components | Job Link™ Charge Kit | | Item Dimensions | 10 x 4 x 7 inches | | Item Type Name | HVACR Charge Kit | | Item dimensions L x W x H | 10 x 4 x 7 inches | | Manufacturer | Fieldpiece | | Measurement Type | Pressure, Temperature | | Model | JL3KR4 | | Number of Items | 1 | | Part Number | JL3KR4 | | Power Source | Battery Powered | | Style | Handheld | | Style Name | Handheld | | UPC | 872641003395 | | Unit Count | 1 Count | ## Product Details - **Brand:** Fieldpiece - **Color:** Yellow - **Item dimensions L x W x H:** 10 x 4 x 7 inches - **Power Source:** Battery Powered - **Style:** Handheld ## Images ![Fieldpiece JL3KR4 HVACR Charge Kit - Image 1](https://m.media-amazon.com/images/I/71htn4QNKjL.jpg) ![Fieldpiece JL3KR4 HVACR Charge Kit - Image 2](https://m.media-amazon.com/images/I/81fGB7KsvfL.jpg) ![Fieldpiece JL3KR4 HVACR Charge Kit - Image 3](https://m.media-amazon.com/images/I/81QCqa0BgqL.jpg) ![Fieldpiece JL3KR4 HVACR Charge Kit - Image 4](https://m.media-amazon.com/images/I/81yTz2d+JPL.jpg) ![Fieldpiece JL3KR4 HVACR Charge Kit - Image 5](https://m.media-amazon.com/images/I/714p11nwJKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ From rookie to pro in one tool upgrade *by C***T on January 9, 2024* This is a game changer for HVAC work.
