## Summary description

Handheld refractometer INSIZE ISQ-RM30 with a 0–32% measurement range for determining concentration of solutions via refractive index. Optical instrument designed for quick liquid testing in laboratories, food production, agriculture and field inspections. Features a compact handheld form factor, prism-based measurement and direct percentage readout suitable for routine quality checks and process control.

## Long description

The INSIZE ISQ-RM30 refractometer is a handheld optical instrument designed to measure the concentration of solutions by determining their refractive index and displaying results directly as percentage values. With a 0–32% measurement range, this compact device is intended for quick liquid testing in laboratories, food production environments, agricultural settings and field inspections where a portable, prism-based refractometer is required for routine quality checks and basic process control.
Advantages
The instrument offers a simple, direct percentage readout that avoids manual conversions between refractive index and concentration. Its compact, handheld form factor and prism-based optical system enable fast measurements with minimal sample volume. The design emphasizes ease of use for operators performing repeated checks and supports on-site testing without the need for complex setup.
Suitable for
 Quality control in food and beverage production (sugar solutions, syrups)
 Field testing in agriculture (sap, sap-sugar estimation)
 Routine laboratory checks where a 0–32% concentration range is appropriate
 Process control and acceptance testing for liquid mixtures
Key specifications
 Measurement range: 0–32% (direct percentage readout)
 Measurement principle: prism-based refractometry (optical)
 Form factor: handheld, portable
 Sample requirement: small liquid drop placed on prism surface
 Readout type: analog/optical scale designed for direct interpretation
 Typical applications: liquids testing for concentration and quick checks
How to use
Place a few drops of the liquid sample onto the clean prism surface, close the cover (if provided) to spread the sample evenly, then look through the eyepiece or read the calibrated scale to obtain the percentage value within the 0–32% range. Ensure the prism surface is clean and free from residues before measurement and perform measurements at a stable ambient temperature where possible to minimize reading variability. After use, clean the prism with an appropriate soft cloth and suitable cleaning solution to avoid damage.
Usage recommendations
For consistent results, calibrate or verify the refractometer against a known standard (for example distilled water or a certified reference solution) before critical measurements. Record ambient temperature during testing if precise comparability is required and avoid mixing different sample types on the prism without thorough cleaning between measurements.
