Hand Held Refractometers

Digital Brake-Chek Fahrenheit Or Celsius $305.00
Check boiling point and water content of brake fluids for optimal braking power. Over time, brake fluids will take on water, break down, and compromise the safety of the brake system. The Reichert Digital Brake-Chek® tests brake fluid in seconds—right at the calipers for the most precise measurement of brake fluid integrity. Available in Fahreneheit or Celsius reading.

Digital Multi-Chek Fahrenheit Or Celsius $305.00
One accurate tester performs three critical tests. Test coolant, battery and windshield fluids. Why take chances? For precise reading of coolant concentration, hydrometers just don't measure up. The Digital Multi-Chek accurately and effectively tests coolant - both ethylene and propylene glycol - as well as battery charge and windshield fluid.

Digital Diesel Exhaust Fluid (DEF)-Chek $305
Digital instrument for testing Diesel Exhaust Fluid (DEF) Maintain optimal SCR performance and keep rolling at 32.5% concentration, 100% of the time. Selective Catalytic Reduction (SCR) systems for diesel automobiles, trucks, buses, and off road equipment require pure Diesel Exhaust Fluid at an exact concentration of 32.5% urea in deionized water. This fluid is known as DEF, AdBlue, ARLA, and AUS 32. Any other concentration compromises the SCR system, which fails the regulatory requirements of governmental agencies such as the the EPA, European Commission, and MLIT. The DEF-Chek® digital instrument accurately measures DEF for the right urea content detecting whether the fluid will do its job in the exhaust system. The world's smallest scientific DEF testing device offers quick, automatic digital measurements in seconds and provides over 10,000+ measurements on two AAA batteries.
Model RC13940013
