If you own a rotary powered car, then you need to know its compression! This is a tool made specifically for rotary engines, using an electronic unit and a pressure transducer, it can measure the compression on each face of the rotor, unlike regular piston engine testers which are useless for a rotary. This listing is for a 1-sensor tester, but I can make one with 2, 3, or even 4 sensors so that you can do 2, 3 or 4 rotors at once! Send me a private message for details! No matter if you are looking into getting a mazda RX8 or RX7, looking to sell it or just be at rest with the condition of your engine, this tool will deliver that which you are looking for:-the compression on each rotor face, in PSI and BAR-the cranking RPM of the starter motor-corrected readings for RPM and athmospheric pressure, in PSI and BAR. This means that it takes into account how weak your car battery is, how worn the starter motor is, and the ambiental air pressure. These factors ensure you get the most accurate result possible! No external calculator/website/paper needed - just watch the screen. All you need to do is remove a sparkplug and turn the engine over for 5 seconds. Then repeat for the other rotor. Its that simple - if you can change a flat tire you can do a compression test. The tool can be used as many times as you need, no restrictions. These units are of great use to potential buyers who do not want to buy a grenaded engine. Sellers are also getting hit with that "but whats the compression like?" question.Considering that a dealership test costs $200-$300, getting the tool for it at less than that is a no-brainer! Not to mention die-hard owners who would want to plan ahead the moment when they have to rebuild. Full instructions are provided. The tester is powered by a 9V battery that may need replacing in 1-2 years. The battery can be swapped out by the customer. Don't pay more than needed - this is the best value for money product you'll ever buy. All units are hand built - no mass production by the thousands - so each unit is individually calibrated. No other tester on sale offers this, as they are made by the dozen at no respect to calibration. Nothing is equally created, but if you calibrate it you get consistent results. The advertised precision is 2 psi or 0.14 bar. That's why no one else mentions how accurate their tester is, since they are made by the numbers, not quality. To be blunt, there has been no alternative so far, and this raised the cost of such an item. Now's your chance not to pay $300 on a tester! I offer a warranty of 1 year starting from the sale date. Full customer support is offered at all times, including weekends. Pretty much anytime I am online, I will take questions.Shipping - regular post is offered, and express services such as DHL, UPS, can be offered but a custom invoice must be made. The cost of express shipping varies by country. You can select any color you wish, so long as I still have that color in stock.Contact me for any other question!
