NUMBER 1 IN LUBRICANT CONDITION MONITORING STM 1 Test Kit DILUTION – ACIDITY – POLLUTION Conforms to the STM 1 specification of the French Navy The tests are simple and rapid, and the enables the operator to make the right decisions to guarantee the lifespan of the engine. The STM1 kit is designed for monitoring 3 main characteristics of the lubricant on the Diesel engine operation site: Dilution of lube oil with fuel oil Pollution with carbon matters Acidity of the aqueous phase The method consists in comparing the viscosity of the used oil with the viscosity of two reference oils of known dilution. Viscosity comparison is done instantly using a VCD falling ball viscometer. Maximum acceptable dilution: 5% typical Sample required: 10 ml Time to result: 3 minutes Carbon Matters (Soot) This test uses a comparative method: a drop of oil to be tested is poured on a special filter paper on which it spreads and forms a spot. The spot is compared to a reference chart for interpreting. Reading: Excellent / Good / Bad Concentration: 0.2% à 2% Sample required: 10 ml Time to result: 1 hour typical Product Code Dimensions: 57 x 43 x 10 cm Weight: 4.5 kg The kit is housed in a strong and light aluminum case. STM 1 Test Kit: MT9032 The kit includes all accessories, reagents and operating manuals for performing and understanding 100 acidity and pollution tests. The number of dilution tests is unlimited.
