JL3MN Manometer Probe Kit, Compatible with Klein Tools ET180 Digital Manometer Compatible with Fieldpiece JL3KM2, SDMN5，SDMN6，ADMN2,HVAC Pitot Static Tube Fit

Pretty nice kit to have as a fairly reasonable price.

They also work well for air volume flow calculations using manometer pressure gauges—reasonable price for the money.

Great set of accessories to get started using a digital manometer. The T-fittings will also act as adapters for various tubing sizes if you pick up a cap to block-off the unneeded end. Any caps, plugs, fittings, and/or tubing needed for a specific job can be easily found on Amazon, or just about any hardware or auto parts store. The parts in this kit are the ones that they will not have.The included roll-up storage pouch is a really nice touch. It keeps everything safe, sorted, and easy to find and access.

I bought this accessory kit for my Manometer. It is essential for taking readings on duct, gas, ect... I Definitely recommend.

Should be in every technicians tool bag.

When I opened the package I could feel that this was a well made kit. The folding storage case was thick and sturdy, and the probes and adapters had a nice solid feel to them. This kit fit the relatively inexpensive red manometer I bought off of Amazon to check my HVAC register pressure. That kit didn't come with the probes, and these work great. I expect that if your buying this kit you probably know how to use it.

To small for a real traverse just a joke

I have been in the HVAC trade for almost 30 years and am now in the role of instructing contractors on equipment, installation and service as a Technical Service Advisor. I am always looking for items to make our trade easier and this one really fits the bill! Ease of use is the first thing that pops out to me. The proper way to test pressure switches on furnaces is to use a tee inline with the pressure hose(s). This is typically something that you would need to source yourself (find some barbed tees at your local home improvement store of the correct diameter), but they are included with the kit. Also included are some nice silicone hoses, a set of pitot tubes with magnets on them and the necessary brass connectors for gas pressure testing, all in a well designed roll-up case with velcro closures.Functionally, you will never have to go looking for anything else to get the job done and the case keep everything together in one place so you don't lose anything. The accuracy of having the correct parts all in one pouch indicated that this is a great value for the money and I would recommend this to anyone in my classes to purchase.
