A ‘ Student-Version Absorption Spectro-photometer’ has been developed, employing a facile fabrication method, for producing a desired quantity of this instrument. The speciality of this student version is that it extends ‘hand-holding’ to the new learner, taking the learner through the intricacies of spectral absorption spectrometry. Experimental runs have also been conducted and found satisfactory. Market launch of this product is in the process.

An automated low cost and hence affordable pH meter has been developed. The feature of automation eases the laborious manual operations of temperature correction and pH calibration.
