Item Description: MISCO Palm Abbe Digital Handheld Refractometer, Glycerine and Propylene Glycol Scales, Concentration, Freeze Point Fahrenheit - Does NOT include a Rubber Armor Jacket. MADE IN THE USA! (The actual unit comes in BLACK!) This instrument will test glycerine and propylene glycol percent concentration by volume and freezing point in degrees Fahrenheit. INSANE PRICE FOR THE POWER! DID WE MENTION THAT IT IS MADE IN THE USA? IT IS! One BRAND NEW Misco Palm Abbe PA203x The Palm Abbe Glycerine Propylene Glycol Refractometer is designed to provide the freezing point and percent concentration of both glycerine and propylene glycol antifreeze solutions. This instrument will test glycerine and propylene glycol percent concentration by volume and freezing point in degrees Fahrenheit. Just place a drop or two of glycerine (glycerol) or propylene glycol in the stainless-steel sample well and press a button. The custom-designed microprocessor delivers a nearly instantaneous readout of glycerine or propylene glycol concentration or freeze point. Nonlinear temperature compensation is automatic and ensures that fluids tested between 0 and 50 C (+32 to 122 F) are measured accurately. Glycerine or propylene glycol concentration and freeze point are easily read on the large dual-line 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. (The actual unit comes in the color BLACK!) Included are: . MISCO Palm Abbe Refractometer, Instruction Manual (Does NOT include a Rubber Armor Jacket) This is the Refractometer of Professionals! The PA203x is equipped with “Automatic Temperature Compensation” for accurate measurements without re-calibration after shifts in ambient working temperature (field use). The "ATC" range is 0 and 50 C (+32 to 122 F) The unit runs off (2) AAA batteries on a LARGE PRINT digital LCD display.
