HVACR Products Visit the Store HVACR Products Visit the Store Review: Well engineered product worth it's price and convinience - Amazing tool - accurate and reliable. Integrating the pressure switch tester is a well thought of concept and very good engineering to integrate into this small form factor. Fieldpiece used to sell the pressure switch tester separately (I guess SDMN1) - which had been discontinued in favor of this product. Does the pressure switch tester justify an additional $100 price tag over its nearest rival ? Maybe not. Especially if you account the cost for a small 6v vaccum pump and some additional silicone tubing. But then that's what they get to charge for innovation, offering convinience and monopoly (Fieldpiece being the only one offering this). So can't complaint. How does this differ from other products ? Other branded and unbranded (Chinese) manometers use differential pressure sensors. Fieldpiece uses standalone pressure sensors on each of it's ports. This allows each port to be read standalone especially when you have both the probes inserted in the duct/plenum for reading static pressure. Other manometers only allow differential readings for this use case. Also stand alone sensors tend to be slightly more accurate. A drift in one does not affect the other. Repairing under warranty is also easy because they only have to replace the pressure sensor which is defective. Something important to note is that Fieldpiece only covers warranty if you buy it from one of their authorized resellers either directly or on desertcart. Fieldpiece refuses to honor warranty if it was sold and shipped by desertcart. They have a list of resellers on their website (who also sell on desertcart) - so be sure that you check before you buy because this is an expensive piece of equipment. Review: Well made - I love mine - Works great as a manometer and the pressure switch tester is excellent too. I'm an HVAC technician and use mine almost every day. Robustly made, and the magnet on the back is excellent for hands free operation. If you buy one and test pressure switches, make use of the "hold" button, and be patient. The pump can sometimes take a minute or so to get set before pumping up, and several times when I first started using this I smashed the "up" button a bunch of times impatiently, and then the pump kicks in and all of a sudden you are passing 10" WC and wondering what happened. So when checking pressure switches, be patient, and make use of the "hold" button. Pressure switches don't fail super often, but with a tool like this in your bag you can quickly figure out if the pressure switch is your problem or if your issue is elsewhere. This also comes with a bag containing all the hoses and attachments for checking pressure switches, gas valves, and checking static pressure in ducting. ## Features - Measures gas pressure, static pressure and differential - Use to test and adjust pressure switches - Features include a backlit dual display, zero adjust button, rugged rubber boot, magnetic hanger and auto power off - Includes: 2 static pressure probes, 2 slide on gas adapters, quick connect leads, 3 hoses and Y-splitter and pump bleed accessory ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IJI0T6U | | Best Sellers Rank | #153,180 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #208 in Multi Testers | | Brand | Fieldpiece | | Brand Name | Fieldpiece | | Customer Reviews | 4.8 out of 5 stars 466 Reviews | | Global Trade Identification Number | 00872641003005 | | Included Components | Meter | | Item Dimensions | 11.5 x 6.5 x 3 inches | | Item Type Name | Pressure Switch Tester | | Item Weight | 1.9 Pounds | | Item dimensions L x W x H | 11.5 x 6.5 x 3 inches | | Manufacturer | Fieldpiece | | Material | Metal, Rubber | | Material Type | Metal, Rubber | | Model | SDMN6 | | Number of Items | 1 | | Part Number | SDMN6 | | UPC | 872641003005 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Fieldpiece - **Item Weight:** 1.9 Pounds - **Item dimensions L x W x H:** 11.5 x 6.5 x 3 inches - **Material:** Metal, Rubber - **UPC:** 872641003005 ## Images ![Fieldpiece SDMN6 Pressure Switch Tester - Image 1](https://m.media-amazon.com/images/I/71-Kn2MusqL.jpg) ![Fieldpiece SDMN6 Pressure Switch Tester - Image 2](https://m.media-amazon.com/images/I/81XbEOuqhQL.jpg) ![Fieldpiece SDMN6 Pressure Switch Tester - Image 3](https://m.media-amazon.com/images/I/81KCSt1csOL.jpg) ![Fieldpiece SDMN6 Pressure Switch Tester - Image 4](https://m.media-amazon.com/images/I/81DZg6WGUGL.jpg) ![Fieldpiece SDMN6 Pressure Switch Tester - Image 5](https://m.media-amazon.com/images/I/81tl3q1XBDL.jpg) ## Questions & Answers **Q: Can this device used to measure blowby pressure on trucks** A: It can only handle low pressures.

Some people may need a meter that reads into the 1,000th's. (I built one that reads into the 10,000th's on the billybbob18 YouTube channel). I don't have video of it, but i tested The SDMN6 against my home built one and they were dead on to within a few 1000'ths at 1inWC. The pressure switch pump is impressive and can end up destroying your switch if you fail to use the bleeder adapter for switches without a bleed port (READ INSTRUCTIONS!, the metal ones usually don't have a bleeder built in). As far as build quality goes, the thing is solid in every way. Don't be dismayed by the fact that you need to zero it. Changes in barometric pressure will throw off the atmospheric reference. When entering a new pressure zone, just re-zero and continue working. Fieldpiece support is the best as well. No regrets. The pressure switch tester adds over 100 to the price of the SDMN5, so if you don't need that, get the 5. ## Frequently Bought Together - Fieldpiece SDMN6 Pressure Switch Tester - UEi Test Instruments PDT650 Folding Pocket Digital Thermometer,Yellow - Fieldpiece PRH2 Digital Psychomotor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4910484-fieldpiece-sdmn6-pressure-switch-tester](https://www.desertcart.us/products/4910484-fieldpiece-sdmn6-pressure-switch-tester) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-31*
