Another nice deal. Aside from this one has AI 😂 Does the ETENWOLF T300 from the other day? I picked up that up for $4 and wondering which one is more accurate that I should go with.

Have T300. Accurate to 0.1 psi up to 150 psi ( tested at 45 F and 100 F ambient vs. Fluke 2700G with 0.02% accuracy full scale). Accuracy increases above 1 psi below 32 F.

functional little unit. Analog would be best (no batts) but this is good also.

Recommend putting AAA energizer ultimate lithium in it. VERY unlikely to leak...10+yr shelf life and more tolerant to heat/cold.

Std. Alkaline in a hot/cold car will most likely leak within a few years.

Bourdon gauge is the best if you can secure an accurate sample. I only check the tire pressure when cold in the garage. No need to carry the pressure gauge in the car.

Most decent AAA batteries don't leak if you use the device once a month. Have a bunch of free AA and AAA heavy duty batteries from HF around 2015. They work fine in home thermostat and remote controls.

Based on Project Farm's Comparison Chart, ETENWOLF has the lowest total deviation for measuring 16 psi and the 2nd lowest for measuring 40 psi. Also ETENWOLF has a better seal rating than AstroAI. However, Project Farm reviewed an old version of the ETENWOLF that had a calibration certificate and the new version does not have one. However, Project Farm reviewed the AstroAI that uses a coin battery.

1. The T300 is very accurate at room temperature.
2. Takes longer to add air to tires since you have to check the dashboard for the air pressure.
3. The batteries in the tires are good for ~7 years. New batteries require tires removal. Minimum $100 parts plus labor.
4. Sensor/wiring can fail. This will disable anti-lock braking, and you will not have tire pressure reading.

I have the current version T300 (cheap batteries, no certificate, and no presta valve adapter). Unit is very accurate down to 45 F. It's not very accurate below freezing (0 C). Suspect the compensation circuit is not optimized for extreme cold temperature. Your photo confirms my observation. On the plus side, air loss should be minimal at low temperature, probably less than 1.5 psi in three months.
