  • MISCO Digital Glycerin/PG Refractomer PA-203
    Digitally test the percent glycerin or glycol to water concentration and freeze point of the loop. Avoid the need for conversion charts and tables required when using “spyglass” models....

  • The Glycerin & Propylene Glycol Digital Refractometer (MISCO Palm Abbe #PA-203X) will test the percent glycerin or glycol to water concentration and freeze point of the sprinkler antifreeze loop. Get fast, precise readings while avoiding the need for conversion charts and tables.

    One tool gives you all this: 

    • Glycerin freeze point

    • Glycerin % concentration

    • Propylene glycol freeze point

    • Propylene glycol % concentration

    • Refractive Index (for AFFF firefighting foam readings)

      Made and serviced in the USA. Available in either Fahrenheit or Celsius freeze points.

      The Palm Abbe is a fourth-generation digital handheld refractometer that puts laboratory precision in the palm of your hand. Just place a drop or two of glycerin (glycerol) or propylene glycol in the stainless-steel sample well and press a button. The custom-designed microprocessor delivers a nearly instantaneous readout of glycerin 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.

      The Palm Abbe refractometer automatically calibrates itself to water and is ready to use in seconds. No more screws to turn and nothing to adjust.

  • MISCO Inline Process Refractometers
    MISCO Inline Process Refractometers allow you to continuously monitor and control the concentration and/or freezing point of glycerin or propylene glycol, supplementing your manual sampling. Connect directly to a PLC, HMI, or other data capture system....

  • MISCO Inline Refractometers are completely self-contained measurement systems and represent a new standard in concentration sensing. Designed for performance, MISCO units are custom programmed to your specific requirements from our extensive scale library.

    The heart of our Inline Sensors is the MISCO OPTICAL-ENGINE®: virtually scratch-proof, precision sapphire optics, 1,024 element detector array and consistent 589.3 nm light source housed in a rugged module to prevent optical movement or misalignment even in the roughest conditions.
