| Specification | AstroAI Digital Tire Pressure Gauge 150 PSI | Meguiar's Gold Class Car Wash 64 oz Liquid Wash |
|---|---|---|
| Price | ₹1,299 | ₹1,799 |
| Weight | 90 g | 1.9 litres |
| Warranty | 1 Year Official Brand Warranty | 1 Year Official Brand Warranty |
| Accuracy | Plus or minus 1 PSI | not published |
| Backlit | Screen and nozzle both lit, which is the point at a roadside at night | not published |
| Battery | One CR2032, several years of use | not published |
| Cold measurement | Tyre pressure rises roughly 1 PSI for every 5 degrees C. Measuring after driving reads several PSI high, and letting air out to correct it leaves the tyre genuinely underinflated when cold | not published |
| Coverage | not published | 1.9 litres gives roughly 60 washes at correct dilution |
| Dilution | not published | About 30 ml per 4 litres of water |
| Not a wax | not published | It contains conditioners but does not add protection |
| pH | not published | Neutral, which is what allows it to be used over wax without removing it |
| Range | 0 to 150 PSI | not published |
| Two bucket method | not published | One bucket wash, one rinse. This is what prevents swirl marks, not the shampoo |
| Units | PSI, BAR, KPA, KG/CM2 | not published |
| Why that matters | not published | Household detergent and dish soap are alkaline and strip wax in one wash. That is the commonest reason a waxed car stops beading after a month |
| Why this matters in India | Ambient swings between a monsoon morning and a May afternoon move pressure by several PSI on their own | not published |
Every row is a figure one or both products record. A blank is a figure the catalogue does not hold, not a zero.
