Abstract
An optical sensor incorporating near infrared optical electronics whic h measures pH in the alkaline region is reported. Contaminants within the aqueous solutions whose pH is being measured interfered with the e vanescent wave sensing technique and a method to overcome this problem is demonstrated.
