Handheld Brix Refractometer

The TeKit RZ113 is a handheld optical instrument that measures sugar concentration on a 0 to 32% Brix scale. It includes Automatic Temperature Compensation (ATC) across a 10 to 30°C range so readings stay accurate without manual correction charts. The device weighs .4 kg and comes with a calibration knob secured by a lock nut and a pipette for sampling.

Brewers, growers and fluid technicians

This refractometer suits brewers tracking wort gravity, growers checking fruit ripeness in the field and technicians controlling coolant or lubricant concentrations. It is not for users who need a measurement range beyond 32% Brix or who require digital data logging and automated sampling. The analog optical scale requires a visible light source to read.

0.2% scale division accuracy

The single specification that decides fit is the .2% scale division across the full 0 to 32% Brix range. This resolution determines whether the instrument can detect the small changes your process demands. If your quality control requires finer increments, this model will not meet the requirement.

Questions about this item

Does the TeKit RZ113 need batteries or an external power source to run all day?

No, it operates entirely on ambient light through the eyepiece, so there is no battery drain or heat build-up during continuous use.

What extra item must I already have to calibrate the RZ113 before first use?

You need a few drops of distilled water or the supplied calibration fluid to set the zero point using the lock-nut adjustment knob.

Can I still use my existing hydrometer alongside this refractometer for brewing?

Yes, the 0-32 % Brix scale with 0.2 % divisions lets you cross-check wort readings against a hydrometer for more accurate alcohol estimates.
