5-scale digital refractometer

The PEAK 5-scale digital refractometer from Old World Industries is a five-in-one instrument for field-testing engine coolant and the concentration of urea in Diesel Exhaust Fluid (DEF). By placing a drop or two of fluid in the stainless steel well and pressing a button, the microprocessor delivers a nearly instantaneous readout and ensures that fluids are measured accurately. The user interface consists of two buttons, one to take readings and the other to move through various menu options. The large backlit LCD display is easily read, even in dim light, and removes the subjectivity associated with interpreting where a boundary line crosses tiny scale divisions. Calibration is automatic and does not require the use of special tools. The 5 Preset scales are: Final Charge Global DAT GIVCOI %, Final Charge Global OAT Freeze Point, NOAT/HD SCA GIVCOI %, NOAT/HD SCA Freeze Point, and DEF Urea%. It meets or exceeds the requirements for refractometers in international standards ASTM 07821 and ASTMD3321, and the kit includes a protective rubber jacket and hard plastic carrying case along with three 1.7 ml disposable pipettes.
