It’s quick, reliable, and gives consistent readings for relative humidity, wet bulb, and dry bulb temperatures, which makes my job a lot easier when diagnosing system performance. The interface is straightforward and easy to navigate, even if you’re in a hurry on a job site. I especially like how fast it responds compared to some older models I’ve used. The build quality feels solid, and it holds up well to everyday use in the field. Another big plus is how well it pairs with other Fieldpiece tools and apps, making it easy to log and track data when needed. That said, battery life could be a bit better if you’re using it heavily throughout the day, but it’s not a dealbreaker. Overall, it’s a dependable, professional-grade psychrometer that delivers accurate results and saves time. Definitely worth the investment if you work in HVAC or need precise humidity measurements regularly. Review: Accurate, precise, and an integral part of any HVAC technicians toolkit - I have the entirety of the JobLink kit sans the amprobe. These are indispensable within the HVAC industry. I’ve been in the residential/light commercial HVAC industry for about 25 years, and definitely don’t miss the days of having to run back, and forth from the indoor unit to the outdoor unit, then back again. These are extremely accurate, and as others have said you can be a good distance away from the psychrometers while being your pressure measurements, and get a solid look at the system as a whole(with the SMAN4 gauges, or the JobLink charging kit). Combine the JobLink static pressure probes, and enter the CFM into the airflow section of the JobLink app, and you can get a continuous reading of BTU’s produced. These psychometric probes are a lifesaver. Especially, if you’re working on an attic system in the dead heat of summer. Aside from being extremely useful when performing maintenance, they are a great diagnostic tool, and with the length of the probe(twss) you can position it to read directly in the airstream(twss iykyk). I can’t say enough good things regarding these, or any tool that’s part of the JobLink family tools, and especially the usefulness of the Fieldpiece app. The app shows you to observe your readings for the aforementioned situation, a combination analyzer, electrically, and historical graphing. The ability to print out a PDF that you can then provide the customer proving your diagnosis, or confirming your repair work(As a qualifying statement prior to the next sentence, the following does not apply to situations where the work wasn’t performed correctly, the diagnoses was incorrect, or damage was caused to the customers home/system)is especially important in today’s world where unfortunately if you don’t document your work, and repairs it can become a he said/she said situation that can put you in a negative position where you can be the recipient of a constant flow of demands for refunds from people exploring the situation in order to get something/anything free, or in extreme cases being caught up in legal issues if you’re not able to 100% verify your work. The Fieldpiece psychometric probes are a great addition to your toolbox that will pay dividends through the future ## Features - Flex Psychrometer Probe - Psychrometer probe for Job Link systems - Compatible with SM380V and SM480V - Powerful 350' wireless range w/no transmitter required - Communicates with Job Link App ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.9 out of 5 stars 760 Reviews | ## Images ![Fieldpiece JL3RH Job Link Flex Psychrometer Probe w/Remote Data Logging for BLE 4.0 Devices, 2.4 GHz Radio Frequency, 0% RH to 100% RH Measurement Range - Image 1](https://m.media-amazon.com/images/I/61rplBrClKL.jpg) ![Fieldpiece JL3RH Job Link Flex Psychrometer Probe w/Remote Data Logging for BLE 4.0 Devices, 2.4 GHz Radio Frequency, 0% RH to 100% RH Measurement Range - Image 2](https://m.media-amazon.com/images/I/81SfkX0EcBL.jpg) ![Fieldpiece JL3RH Job Link Flex Psychrometer Probe w/Remote Data Logging for BLE 4.0 Devices, 2.4 GHz Radio Frequency, 0% RH to 100% RH Measurement Range - Image 3](https://m.media-amazon.com/images/I/81lMB87ulvL.jpg) ![Fieldpiece JL3RH Job Link Flex Psychrometer Probe w/Remote Data Logging for BLE 4.0 Devices, 2.4 GHz Radio Frequency, 0% RH to 100% RH Measurement Range - Image 4](https://m.media-amazon.com/images/I/81gCaqkIbPL.jpg) ![Fieldpiece JL3RH Job Link Flex Psychrometer Probe w/Remote Data Logging for BLE 4.0 Devices, 2.4 GHz Radio Frequency, 0% RH to 100% RH Measurement Range - Image 5](https://m.media-amazon.com/images/I/81PuUyVmbHL.jpg) ## Questions & Answers **Q: Do these probes clog up easily when inserting into and/or thru duct-board for temps (TD)?** A: Yes they can, the best thing to do is use a screwdriver or awl to make the hole before inserting the probe. You don’t want to use the probe to make the hole. Once the hole has been made I haven’t had any issues with the probe clogging up when inserting. **Q: Does this come with 2 probes?** A: No **Q: Doest this connect to the sm460?** A: No **Q: Does jl3rh work with current version of apple job link app on my phone? requires any other devices to connect to the app?** A: Measurequick app or fieldpiece joblink app ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pricey but worth it *by C***D on March 25, 2026* I’ve been using the Fieldpiece psychrometer for a while now, and it’s become one of my go-to tools for HVAC work.
