Product Comparison<\/div>\n

Product Comparison<\/h2>\n

PT650 is the transmission oil pressure gauge in the AUTOOL PT pressure tester range. Compare the test system, pressure range, connector set, display size, data function, toolbox, and application before choosing a model.<\/p>\n

\n
PT650 Focus<\/span>Designed for automotive transmission pressure system testing with a 2.8-inch display, 0-30 bar class range, 12-type connector set, equipped toolbox, and data lock \/ clear \/ record function.<\/strong><\/div>\n
PT610<\/span>Cylinder pressure gauge for engine cylinder pressure testing, with 6 sets of data storage and 10 types of accessory connectors.<\/strong><\/div>\n
PT620<\/span>Engine oil pressure gauge kit for engine oil circulation system testing, with 18 types of accessory connectors.<\/strong><\/div>\n
PT630 \/ PT635<\/span>Fuel pressure gauge options for automotive fuel system testing. PT635 is the high-end fuel pressure gauge version with more connector types.<\/strong><\/div>\n
PT640 \/ PT660<\/span>PT640 is for GDI fuel pressure testing up to 0-360 bar. PT660 is for internal brake system fluid pressure testing and supports dual-channel brake pressure measurement.<\/strong><\/div>\n
Decision Check<\/span>Choose by test system first: cylinder, engine oil, fuel, GDI fuel, transmission oil, or brake system. Do not use PT650 as a substitute for fuel, GDI, cylinder, or brake pressure tools.<\/strong><\/div>\n <\/div>\n <\/div>\n
