Measure propylene glycol (PG) concentration and freezing point instantly and accurately with the Palm Abbe digital refractometer. A refractometer is fast, convenient, and easy to use. Simply place a drop or two of propylene glycol in the stainless-steel sample well and press a button. The custom-designed microprocessor delivers a nearly instantaneous readout of propylene glycol concentration in percent by volume or freeze point in degrees Fahrenheit. Nonlinear temperature compensation is automatic and insures that fluids tested between 0 and 50 C (+32 to 122 F) are measured accurately. Propylene glycol concentration and freeze point are easily read on the large back-lit LCD display, even in dim light. Digital readings remove 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 two buttons, one to take readings and the other to step through various menu options. Calibration is automatic and does not require the use of special calibration solutions, or tools. The Palm Abbe propylene glycol refractometer automatically calibrates itself to water and is ready to use in seconds. No more screws to turn and nothing to adjust. The Palm Abbe is a fourth-generation digital handheld refractometer that puts laboratory precision in the palm of your hand. Not just laboratory precision, but laboratory precision for the price of a traditional analog refractometer. It is exactly the kind of bold, cutting-edge technology you would expect from MISCO, the company that pioneered the digital handheld refractometer.
