Indicators

Chemical indicators are substances that change colour in response to pH changes, temperature, or the presence of specific chemicals. Our range includes universal indicator solution, phenolphthalein solution, methyl orange, and other acid-base indicators for chemistry laboratory use.

Used in titrations, pH demonstrations, and general chemistry experiments, indicators provide a simple, visual way to detect the endpoint of a reaction or determine approximate pH without electronic meters.

SmartLabs supplies chemical indicators to schools and labs across South Africa. Browse our range for reliable, affordable indicators for your chemistry teaching and laboratory work.

Weighing indicator in use

What is a weighing indicator?

A weighing indicator is the digital display and control unit that reads out the mass measured by a separate load cell or weighing platform, such as a floor scale or platform sensor. It handles the readout, taring, unit conversion and often data output to a printer or computer.

SmartLabs stocks weighing indicators suited to pairing with compatible platform scales and load cells across bench and industrial weighing setups.

Common uses of weighing indicators in the lab

Where weighing indicators do the readout work.

  • Platform scale readout

    Platform Scale Readouts

    An indicator pairs with a separate weighing platform or floor scale to display an accurate reading.

  • Batching and process control

    Batching & Process Control

    Indicators with hold and tare functions support consistent, repeatable weighing during batching.

  • Data logging

    Data Logging

    Many indicators can output readings to a printer or computer for record keeping and traceability.

  • Replacing a faulty display

    Replacing a Faulty Display

    An indicator can restore a working readout to a platform scale whose original display has failed.
