Review: Very handy - It’s a good piece of equipment and works as it should. Review: Make sure you have a snug fit with your tubing - This is a basic unit that is simple to use and easy to read. I needed it to calibrate an ERV. I originally had a very hard time getting a stable reading and even using some stuffing around the tubing to make a better seal didn't help. I bought some natural latex tubing that had a better seal which made things much better and repeated readings were stable. The magnet in the back was very handy to affix the meter in a good location so my hands were free to make the adjustments. I have a second and bigger ERV to install but I'm confident that calibration will go smoothly. If I had to complain about something, it would be the case. It's pretty cheaply made and doesn't really have a good layout for the meter and tubing. But it does it's job. ## Features - MEASURE STATIC AND DIFFERENTIAL pressure from two ports in air and gas systems - MONITOR AND TROUBLESHOOT problems in HVAC Systems with a range of +/- 60 inH2O and full scale accuracy of +/-1.5-Percent - STRONG MAGNET ON BACK secures manometer for hands-free operation - ELEVEN UNITS MEASURED: Easily toggle between inH2O, bar, oz/in2, psi, mbar, kPa, inHg, mmHg, kg/cm2, ftH20, and cmH2O - LARGE BACKLIT LCD provides easy viewing in low light conditions and shows values when toggling between minimum, maximum and average ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B099ZYCV1L | | Best Sellers Rank | 156,034 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 554 in Pressure & Vacuum Measurement | | Brand | KLEIN TOOLS | | Customer Reviews | 4.6 out of 5 stars 625 Reviews | | Global Trade Identification Number | 00092644693366 | | Included Components | Manometer, 6.56' (2 m) x 1/8" (3 mm) Inside Diameter Silicon Tubing, 3 x AAA Batteries, Pouch, Instruction Manual | | Item Dimensions | 6.3 x 3.5 x 15.7 centimetres | | Item Type Name | Digital Manometer, Air and Gas Pressure Tester, Differential Dual Port Pressure Gauge, Large LCD Display with Backlight Klein Tools ET180 | | Item Weight | 168 g | | Item dimensions L x W x H | 6.3 x 3.5 x 15.7 centimetres | | Item weight | 168 g | | Manufacturer | Klein Tools | | Manufacturer Part Number | ET180 | | Material | Blend | | Model Number | ET180 | | Number of Items | 1 | | Number of items | 1 | | UPC | 092644693366 | | Unit Count | 1.0 count | | Unit count | 1.0 count | ## Product Details - **Brand:** KLEIN TOOLS - **Item dimensions L x W x H:** 6.3 x 3.5 x 15.7 centimetres - **Item weight:** 168 g - **Material:** Blend - **Number of items:** 1 ## Images ![Digital Manometer, Air and Gas Pressure Tester, Differential Dual Port Pressure Gauge, Large LCD Display with Backlight Klein Tools ET180 - Image 1](https://m.media-amazon.com/images/I/514T-Ymk9JL.jpg) ![Digital Manometer, Air and Gas Pressure Tester, Differential Dual Port Pressure Gauge, Large LCD Display with Backlight Klein Tools ET180 - Image 2](https://m.media-amazon.com/images/I/61Z9iRFybEL.jpg) ![Digital Manometer, Air and Gas Pressure Tester, Differential Dual Port Pressure Gauge, Large LCD Display with Backlight Klein Tools ET180 - Image 3](https://m.media-amazon.com/images/I/61r3RY7UQoL.jpg) ![Digital Manometer, Air and Gas Pressure Tester, Differential Dual Port Pressure Gauge, Large LCD Display with Backlight Klein Tools ET180 - Image 4](https://m.media-amazon.com/images/I/51dIgPByZuL.jpg) ![Digital Manometer, Air and Gas Pressure Tester, Differential Dual Port Pressure Gauge, Large LCD Display with Backlight Klein Tools ET180 - Image 5](https://m.media-amazon.com/images/I/61-PnCScYmL.jpg) ## Questions & Answers **Q: Will this work to check pressure switches** A: Yes **Q: What is the precision in "H2O, 0.01?** A: + or - 60.32 is the range and the resolution is .01 **Q: There's no how video ofnthis product???** A: Try YouTube **Q: What is the difference between p1 and p2? which side is the negative pressure side? i’m resisting sucking on the hose to determine info missing.** A: Both the same- can be set to use one Or two Or both ## Customer Reviews ### ⭐⭐⭐⭐ Very handy *by P***R on 30 May 2026* It’s a good piece of equipment and works as it should. ### ⭐⭐⭐⭐⭐ Make sure you have a snug fit with your tubing *by G***L on 17 February 2022* This is a basic unit that is simple to use and easy to read.
