Overview

schoollabmanufacturers.com manufactures school chemistry pH meters in India — the SLM-PH-100 digital pH meter is the standard choice for WAEC, KNEC, Cambridge IGCSE, and CBSE chemistry and biology practical laboratories. pH measurement is required in multiple secondary school science contexts: acid-base chemistry, soil pH in biology, water quality in environmental science, and buffer solutions in biochemistry. Our school pH meter range covers entry-level (0.1 pH resolution) to laboratory-grade (0.01 pH resolution) instruments.

Frequently Asked Questions

Does the pH meter work with African electricity supply?

Yes. The SLM-PH-100 operates on 4×AAA batteries (included) — no mains electricity required. This is ideal for schools with unreliable electricity supply or for outdoor fieldwork (soil pH and water quality testing). The SLM-PH-200 and SLM-PH-300 can operate on batteries or USB power (5V USB adapter included).

What is the difference between a pH meter and pH indicator paper?

pH indicator paper changes colour to give an approximate pH reading (±0.5-1.0 pH unit). A digital pH meter gives a precise digital reading to 0.01 pH units — 50-100 times more accurate. WAEC and KNEC chemistry practicals require digital pH meters for accurate acid-base titration endpoint detection and buffer preparation.
