On-Site Analysis introduces the OSA4 CoolCheck Coolant Analyzer. The high-tech analytical touch-screen instrument automatically performs up to nine coolant and DEF diagnostic analyses, on-demand in the customer's service bay and all in less than one minute. The OSA4 CoolCheck utilizes sophisticated components that instantly capture data and compare it to known norms, identifying abnormal or severe coolant system conditions. The test data can be (thermal) printed or wirelessly transmitted to LubeTrak, On-Site Analysis' password protected, data-mining and storage tool. The report identifies the type of coolant, boil point, freeze point, clarity, contamination level, nitrite level, percent glycol/water mixture, color, and the percent Urea for DEF.
