Tst

Hi,
Just wanted to add a clarification. We also agree that any system that carries 80 pounds of air or more should have metal valve stems.
507 & 507 Flow thru come with replaceable batteries and last between 9 months and a year. They are replaced by the customer and are #CR1632. The cheapest place to get them are at www.amazon.com We use the Energizer brand.
The 510 systems come with a sealed sensor which is what we use because we don't want to mess with yearly battery changes. It is great if you have a boat trailer because the tires have to go into the water. Those sensors last 5 to 7 years. At the end of the battery life, you would send in the sensor to TST with $20.00 {They are normally $50.00 each}and they send you another sensor.
Hope this helps, Di

507 are flow through sensors but will require metal valve stems. The 510's aren't flow through but don't require metal stems. The batteries on the 510's last about a year. I use the 510's and have had no problems with them.

Think I got all that wrong. My apologies. I have the 507 with replaceable batteries and non flow through sensors.

507s have user replaceable batteries, 510s need sent in to replace the batteries.

Any of the on stem sensors require metal stems. I have the 507, and I had metal stems, but with rubber snap in seats. That is not what is required. They need full metal, that have a nut to hold them in the wheel. I had one of my rubber seated stems break, at the rubber seat. Luckily on a short trip. I had all the wheels fitted with full metal stems. No more worries now.

Taking truck in tomorrow to have valve stems replaced with all metal before I install the Tire Minder..

I'm sitting here laughing and can't seem to stop........LOL

Yeah, you're right, you sure did get it wrong, but I got a good laugh out of it.

I have a comparison sheet that I made up which explains the difference. If you would like it just let me know.
The screens on both monitors are with a 1/4" of each other. Diana

The 507 monitor is smaller, batteries are replaceable on the 507 sensors, also there are optional flow-thru sensors and in-wheel sensors (also flow-thru) with a 7 yr battery life.

The 507 has consumer replaceable batteries, 510 does not.

About $60.00
