TST FLOW THRU System with 4 to 12 Sensors

Purchased the 507 with 6 flow thrus and 4 caps. Very happy overall, the setup appears a little daunting at first mainly because most won't read instructions or watch available videos. But after very short learning period I was able to set up and have all mine programmed in less then hour, extremely useful is you can program in the comfort of your coach then go out and install them in short order. Unit comes with a booster for the Toad but before i installed (in Battery Compartment ) I was picking up all 10 transmitters and the pickup was approximately 40' away. The ability to replace batteries instead of returning them is a great plus for the system, excellent piece of gear.

We bought this through techno RVs Amazon store. The few questions I've had have been answered quickly and thoroughly. Their information videos and instructions are priceless. They were recommended by the folks at Changing Lanes Youtube page. Can't go wrong buying from them.

Overall Impressions… super glad I now have this system… and yes, I would make this purchase if I was faced with this decision again.
The customer experience is always top shelf positive with Techno RV… no different this time. I purchased the TPS TPMS system with 10 flow-thru sensors... will soon purchase 2 more for my spare tires. I have used the system for about 2 months. The system seems to work as advertised… provides great piece of mind.
I have a couple of points that I would mention to those considering making this purchase.
#1 Know that it is extremely difficult to install sensors on inside rear dual wheels (unless you remove the outside tires first). I have an F350 dually. When I received the sensors, I set them up and immediately put them on my truck tires. This was much more of a challenge than I had anticipated. I have average size hands… it was quite a challenge attempting to screw the sensors onto the inside rear wheels stems… probably took me 20-25 minutes to contort my hands/fingers to the right angle so as to not cross thread them… and once I finally had them seated properly, I really couldn’t access them to adjust the air pressure. Eventually, I stopped being lazy, jacked up the truck and pulled off the outside tires. Then I added a 45 degree extensions to both inside tires and then added the sensors. Lesson learned: if you have a dually, pull off the outside tires, use extensions and the system will work better for you.
#2 With my truck, the flow-thru sensors are too long to be able to add air to my front tires and the rear dually outside tires. The only way to add air to these 4 tires is by removing the sensor, airing it, then replacing the sensors. I’ve tried to add 45 degree extensions… they don’t fit… I plan to try 90s or 135s.
All this being said, I am quite happy and a bit relieved that I finally have this system working for me. Great decision to purchase this system, even at this high cost. It’s worth the insurance in knowing.

Overall, the system works very well and I’m happy with it.

Syncing the sensors to the receiver is straightforward if you have the instructions in front of you, but the process is not as intuitive as it could be. The flow-thru sensors feel solid and tough. I haven’t had any air leaks. I’ve put 1300 miles on them, including through some rain. I haven’t had a single reception issue so far with receiving signals. I’m able to pick up all sensors on my 37 foot fifth wheel from the truck without the signal booster. I assume the booster will be needed as the batteries age.

The kit comes with extra o-rings and screws for the inevitable battery replacement, but no extra locking nuts. So, of course, I lost a locking nut during the first install. Fortunately, spare hardware kits are available.

Pressure indications are all within 2 psi of my gauge. The monitor isn’t bright enough in sunny conditions. It’s readable, but the monitor looks like a dim white over black LCD display. Brightness is perfect at night. Be aware the sensors measure temperature of the air flowing around them; they don’t touch the tires. My tread temperatures run 30-40 degrees above what the sensors report. It’s useful information, but there’s no substitute for checking tire and drum temperature with a non-contact infrared thermometer at each stop.

This product is a life saver s d reduces the worry of not knowing what’s going on w the trailer tires. After a blowout and $6k n damage I’m a little nervous now so bought this.

Keep in mind....YOU MUST HAVE METAL VALVE STEMS. Not just a metal thread and a full rigid metal valve stem that doesn’t bend with the flow through system. Although not much weight to them, the spin at highway speed can cause issues w the valve stem pulling free and leaking. It happened to us recently but the m alarms went off and we avoided a blowout. We are switching out stems now w local tire dealer.

Awesome product.

Being able to see my tire pressure n tire temp is peace of mind as I travel. good product with great support. If you don't have one...... get one!
I will continue to buy from Techno RV... next purchase is on my list and going into the shopping cart soon!

Installed on a 28' 5th wheel. First trip with sensors, it saved me twice. On the way to Yellowstone, after driving 400 miles, I noticed 1 tire had dropped 15 psi. I figured I picked up a nail in the tire. I monitored the tire and it held the pressure until I got to the camp site. Without the sensor I would not have know about the nail until I was getting ready to go home a week latter. I fixed the tire at the old faithful car repair shop ($56 to fix a flat). On the way home, I'm driving through Denver at 70 mph when the alarm goes off. The pressure was dropping quick, but I had time to move over 3 lanes of traffic and find a safe place to change the tire. No damage to the tire, rim or trailer. It was also nice not looking at the tires in the mirrors every 5 minutes.

I recently purchased the TST TPMS for my new Class C 32' motorhome. I bought 6 flow through sensors and 4 cap sensors for our Toad. My wife thought this was an expensive toy since we are Canadian and I had to pay US dollar conversion plus GST on the purchase. Anyway, Once I got the TPMS i installed it and set it up as per the instructions. ( Very Simple to setup). It took a few tries to get the tire pressure correct on all ten tires but not a big issue. So here's the best part. On our very first trip we were on our way to the camp ground when 40 min in to the trip the TPMS started beeping. As I looked at the monitor I noticed that a rear inside tire was loosing pressure. The TPMS gave me enough time to find a safe place to pull over before the tire went to zero. This system saved me a tire and potential under-carriage and sidewall damage to my RV by alerting me the moment the tire started losing pressure. My problem? I broke a tire valve. So this system saved me possibly thousands of dollars by alerting me to the pressure loss in time to pull over before any damage or tire loss could occur. The wife no longer thinks of this system as a toy but as a necessary piece of safety equipment. If you only buy one thing for your RV this year this TPMS from TST has to be the item you buy to safe guard your RV and your Family.

There customer service is great. Eric took my order even on a holiday weekend, and it showed up at my door in 3 days. I would not hesitate to order from Techno RV again. The TST 507 is a great product with good features. These people are great. But don't take my word for it, order something from them..
