The PLT9020 Digital Refractometer is easy-to-use battery-powered instrument, ideal for Windshield Cleaner, Ethylene Glycol and Propylene Glycol Antifreeze Fluid, Battery Fluid  and Urea (NH2)2CO measurements on the automotive industry. The instrument automatically compensate for sample temperatures as measured at the prism surface.

PLT9020 is fast, convenient, and easy to use. Simply place a drop or two of fluid in the well and press a button on the keypad. The custom-designed microprocessor delivers a nearly instantaneous readout in refractive index, degrees Brix, or any one of a thousand different units of measure, allowing you to read directly in the units you desire. Nonlinear temperature compensation is automatic and insures that fluids read between 0 and 50 °C (+32 to 122 °F) are measured accurately.
The large dual-line LCD display is easily read, even in dim light, and removes the subjectivity associated with interpreting where a boundary line crosses tiny scale divisions. And, it is so easy to use! The user interface consists of three buttons, “read” to take readings, “cal” to make calibration, and “scale” to step through various unit options.

Rugged Ergonomic-Design

The PLT9020 fits like a glove in the palm of your hand. The weight of its evenly-balanced design can be held easily in any size hand, even during extended periods of use. The positive response buttons on the keypad provide tactile feedback to the operator when pressed.
A strong plastic enclosure is sealed to guard against liquid and dust penetration, while an integrated prism cover helps prevent sample evaporation and protects the sapphire measuring surface from possible damage. The cover also shields the optics from the influence of strong ambient light, making the DR605 ideal for use indoors or in direct sunlight.

An Outstanding Value

Calibration is automatic and does not require the use of special calibration solutions, or tools. The PLT9020 refractometer automatically calibrates itself to water and is ready to use in seconds. No more screws to turn and nothing to adjust.
Because the PLT9020 offers great performance and accuracy at a very affordable price, there is no need to make trade-offs between accuracy and affordability. The PLT9020 provides high-end performance and precision at a low price; making the PLT9020 one of the best values available.
