Technical Specifications

Advantages

The Source of Truth
Eliminates the guesswork of visual checks with an immediate optical reading of fluid strength, helping prevent blind dosing and unnecessary concentrate use.

Universal Compatibility
Engineered to read the refractive index of major coolant types, including full synthetics, semi-synthetics, and high-oil emulsions.

Optimized 0–18% Scale
Unlike standard 0–32% food-grade units that can be difficult to read at lower levels, this refractometer focuses on the 0–18% range for better resolution in the critical 5–10% operating zone.

Battery-Free Reliability
Uses ambient light and precision prism optics, keeping it ready for use without batteries, charging, or electronic failure points.

Technical Overview

  • Scale Range: 0% – 18% Brix
  • Measurement Type: Optical Refractive Index
  • Compatibility: Synthetic, Semi-Synthetic, Soluble Oils
  • Focus: Adjustable Eyepiece
  • Construction: Heavy-Duty Aluminum Body with Rubber Grip
  • Included: Pipette, Calibration Screwdriver, Carrying Case

Why You Need This
Coolant concentration changes daily due to evaporation (which thickens the mix) and drag-out (which thins it). The only way to maintain a stable 7% mix is to measure it daily.

The "Refractometer Factor"
This device reads in "Brix." To get the absolute concentration, simply multiply the reading by your coolant's refractive factor (e.g., Reading 5.0 x Factor 1.4 = 7.0% Concentration). It is the standard method for all ISO-certified machining facilities.

Applications

  • Daily Sump Concentration Checks
  • Fluid Maintenance Audits
  • Rust Issue Diagnostics
  • Coolant Charge Verification
  • Tool Life Optimization

Description

The essential verification tool for precision fluid management. This Industrial Optical Refractometer features a specialized 0–18% Brix scale, specifically calibrated for the reading of metalworking fluids. Compatible with all synthetic, semi-synthetic, and soluble oil coolants, it allows operators to instantly verify sump concentration with a single drop, ensuring that machining processes remain within the safe engineering limits for tool life and rust protection.

The efficient, fluid-saving solution for tramp oil management. The Coolant Skimmer 2 builds on the robust design of the Skimmer 1 by adding an integrated Gravity Separator Tank. While standard skimmers can accidentally remove valuable coolant along with the waste oil, this unit captures the skimmed mixture, allows it to separate, and automatically returns the "good" coolant back to the sump. This ensures that you are only disposing of pure waste oil, significantly reducing your coolant disposal costs.

Industrial-grade chemical test strips specifically engineered for the rapid measurement of pH levels in metalworking fluid sumps. Oemeta pH Test Strips provide the critical data needed to diagnose and prevent smelly sumps and machine corrosion by identifying acidity shifts that compromise the biological and chemical stability of the emulsion.

Industrial-grade chemical test strips specifically engineered for the rapid measurement of water hardness in metalworking fluid sumps. Oemeta Hardness Test Strips provide the critical data needed to diagnose and prevent foaming, sticky residue, and premature tool wear by identifying calcium and magnesium levels that compromise emulsion stability.

Industrial-grade chemical test strips specifically engineered for the rapid and accurate measurement of Oemeta coolant concentration. Unlike standard refractometers, the Easy Check system provides a precise reading of active ingredients while remaining unaffected by tramp oils or suspended solids, allowing for superior control over fluid property parameters.

The robust, cost-effective solution for mixing metalworking fluids at the drum level. This Venturi-style mixer utilizes a solid machined body to blend water and coolant concentrate via suction force. With a wide adjustment range of 0% to 16%, it is capable of handling everything from light grinding fluids to heavy-duty tapping oils. It features an integrated vacuum break safety system, specifically engineered to eliminate the "siphoning effect" that causes messy and hazardous coolant spills on the shop floor.

Technical guidance & FAQs

Applications and materials

The Oemeta optical refractometer supports concentration checks during metalworking-fluid maintenance. A Brix reading is an optical measurement that must be interpreted for the particular coolant rather than automatically read as coolant percentage.

Choosing a configuration

Select the appropriate measuring range and use the coolant’s refractometer factor or specified method. Check the instrument calibration and obtain a representative sample before interpreting the scale.

Compatibility and use

Do not use a refractometer reading as a direct pH, water-hardness or microbial test. Contamination and an indistinct reading may require another specified fluid-checking method.

Technical documents

Contact Tech Tool for the current product information and instructions for Coolant Refractometer.

Is Brix the same as coolant concentration?

Not automatically. Apply the factor or interpretation specified for the exact coolant.

Does the refractometer measure pH?

No. Use the appropriate pH test for acidity or alkalinity; it is a different measurement.

What if the optical boundary is difficult to read?

Check sampling and instrument condition and use the fluid’s specified alternative test or technical support rather than guessing a result.
