Microprocessor Controlled pH Analyzer (PHAN)

pH measurement is so basic and a fundamental requirement in so many fields that people have stopped thinking further about it long ago. But Labindia with its commitment to Quality has not! Labindia has designed and built the most compact, accurate and user-friendly pH Analyzer with unmatched features.

pH is a temperature dependent phenomenon, hence temperature compensation is essential. This instrument gives simultaneous digital read-out of pH & temperature, with automatic temperature compensation.

This instrument has four sets of 10 memory readings with averaging facility, a user-friend feature.

Correct pH measurement and control of pH are the prime factors for successful purification of water, effluent treatment, food processing, manufacturing of sugar and quality medicines.

The equipment comes to you backed by Labindia protection and prompt after-sales-service.

It is a pH meter with a difference you can measure!
