Does anyone have personal experience using the LS790B to detect leaks in R410A systems -- how did it perform?

I used it and it did work. Then another much more experianced HVAC Tech told me this particular model is one of the better ones. Good Luck.

I have used it to find an iron pipe about 18" underground. Sometimes it would lose track of the pipe and then pick it up further down the line. Not sure why this is. If it could only find exactly where the leaks are it would really be amazing! Unfortunately, metal detectors are not designed to locate leaks, they just locate the pipe which is a big help. I have found three leaks in an old irrigation system thus far but the next one is still eluding me. There must be a leak as water is going in and not coming out. It has also picked up miscellaneous things a couple of inches from the surface located while searching for the pipe. I have been very pleased with it especially given the price.

This unit doesn't need much of a warranty as one could test it by placing a few drops of water over the sensor. It should start blasting loudly. If it alerts someone just once to water (where it shouldn't be) then it's worth its meager price of about $10. It is a very useful device in monitoring unwanted leakage from water heaters, frozen pipes, or seeping foundations. It is well worth the investment.

First of all, the glasses are only one part of the system. You have to buy leak detection additive. It put a little UV reactive in the oil that when a UV light is shone on the leak, you can trace the source. I used it on a motorcycle because I couldn't see if the leak was coming out of a seal or a case half.

I have used it for R134A and R12. It works better than any other detector i have used over the years and it is unaffected by the wind which is a big plus. You have to be patient as it takes a few minuits to warm up. However there is still no substitute for pressure testing with compressed nitrogen to determine leak locations.

They are two different sensors, i recommend going to the Denso website to get the two part numbers. The upstream fails more often and the downstream one is usually cheaper.

Possibly a defective unit? I think if you have good connections that do not leak, beyond that I would return the unit for another one. My unit has worked great from day 1.Good Luck, Dan

The only way I detect leaks in toilet tanks is by hearing dripping water in them and then investigating. This device is still working great in the tank I installed it since my original review (2+ yrs). Maybe I don't understand the question.CB

This is exactly what I use it for - a utility room water alarm. By itself, it will sound an alarm. If you get the Ideal Security Base Unit (which I did), it will send a signal to this unit causing the unit to call you or any other designated phone number in case you are not home to let you know the sensor has been activated by water.

icould only tell you i had a hard time finding a large leak.i would tell you that the best thing you can use is dye in the system it is no mistake as to where the leak is.if you buy spendmaybe half the money.make sure it will pick up all the new freon as there are a lot of different types of freon new to the market.mostly i worked on autos and aircraft.some central air. try yellow jacket if you must have one. leak detectors are hit or miss.ok for blind spots where you cannot see dye because of obstruction. i chooseleak detecor dye using a caulking type.or just buy a cheap detector just as good. tony phila.pa. hope this helps you. icould only tell you i had a hard time finding a large leak.i would tell you that the best thing you can use is dye in the system it is no mistake as to where the leak is.if you buy spendmaybe half the money.make sure it will pick up all the new freon as there are a lot of different types of freon new to the market.mostly i worked on autos and aircraft.some central air. try yellow jacket if you must have one. leak detectors are hit or miss.ok for blind spots where you cannot see dye because of obstruction. i chooseleak detecor dye using a caulking type.or just buy a cheap detector just as... » Read More icould only tell you i had a hard time finding a large leak.i would tell you that the best thing you can use is dye in the system it is no mistake as to where the leak is.if you buy spendmaybe half the money.make sure it will pick up all the new freon as there are a lot of different types of freon new to the market.mostly i worked on autos and aircraft.some central air. try yellow jacket if you must have one. leak detectors are hit or miss.ok for blind spots where you cannot see dye because of obstruction. i chooseleak detecor dye using a caulking type.or just buy a cheap detector just as good. tony phila.pa. hope this helps you. « Show Less

Have not had the experience. I can only refer you to the installation instructions, under operational summary, page 17. It says a blue blink every 5 seconds is a previous alarm condition at an unidentified source.

Yes. This device is remarkable. The sensitivity is almost like magic. I would highly recommend this detector to be used by EVERYONE, regardless of whether or not you think you might have a problem with water leaks. Under you lavatory vanities, kitchen sink cabinet, close to your water heater. The product is very affordable and requires no installation. It is virtually unnoticeable until it detects a leak. Once the alarm goes off, there will be no question in anyone's mind that there is a problem. Get some and prevent a very costly water intrusion experience.

I appreciate the answer and will persue the LN-950 system. Cost is no object as the project is small but very important not to fail. Thanks Byron

I returned this unit months ago and I don't have much luck with it. It leaks through the main system. Go check out the Costco model which I am very please with it.

It uses the same technology however it is different due to the fact that this device makes real time calculations within the device.The display will change colors from these calculations determining if you have a leak.

I have not done much with the sensors to date. Most of the sensors are simple digital/ analog I/O interfaces which would just require an appropriate I/O selection on the microcontroller. If you have questions about a specific module, I could take a quick look and let you know. I had the same reaction with the lack of documentation but I am an electrical engineer so I am not particularly worried about figuring out the details.

I have found none and have tried several. The instructions are extremely poor and the setup even worse. Honeywell claims this as a feature but doesn't support it. If you are using a Foscam, I recommend using the Foscam app so you can view cameras anywhere over the internet.
