S-Range Digital Colorimeter - 240V
S-Range Digital Colorimeter - 240V (Product Code: SLE/ME/40) is a single-cuvette digital colorimeter used to measure the absorbance and transmission of coloured solutions in school, college and teaching laboratories. Chemistry and biology teachers use it for concentration and reaction-rate work, and its eight colour filters span 430–700 nm with push-button automatic zeroing. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory analytical instruments supplier.

What Is the S-Range Digital Colorimeter Used For?
Colorimetry lets students turn the intensity of a colour into a number. With the S-Range Digital Colorimeter, a class can prepare standard solutions, plot absorbance against concentration to demonstrate the Beer–Lambert relationship, and then read an unknown sample from the calibration line. The same instrument follows colour changes over time in reaction-rate and enzyme experiments, which makes it a versatile colorimeter for India's school and college labs.
Choose the filter whose colour is complementary to the solution (for example, a red or orange filter for a blue solution), zero the instrument on a blank with one press of the switch, then insert each sample cuvette in turn. Because the colorimeter is insensitive to normal room lighting, the lab does not need to be darkened, and the 0–1V output can feed a datalogger or computer for continuous recording.
What to Specify When Ordering
- Confirm that your mains supply suits the 240V version.
- Number of cuvettes needed — the single holder takes 10 mm path length cuvettes.
- Whether a Spare Colour Filter Wheel should be quoted with the instrument.
- Whether you will connect the 0–1V output to a datalogger or computer, so we can advise on the connection you need.
