Checker Hand Digital Ph Meter

Product Code : LSK-CL-10071

Checker Hand Digital Ph Meter (SKU LSK-CL-10071) is a pocket-sized digital pH meter that reads 0.0 to 14.0 pH, designed for classrooms and for measurements in the field. It is calibrated manually at two points using two trimmers, with manual temperature compensation, and is built to be simple, rugged and practical for students. Science Lab Supplies, a chemistry lab instruments supplier in Ambala, India, supplies it to schools, colleges, training institutes, tender contractors and distributors.

Specifications

This handheld meter shows pH to one decimal place across the full 0.0–14.0 scale. Calibration is a manual two-point procedure: the user sets each buffer reading with its own trimmer. Temperature compensation is also manual, keeping the design simple for teaching and field trips.

Applications and Experiments for the Pocket Digital pH Meter

The pocket digital pH meter replaces colour matching with a direct number, so students can compare acidity accurately and repeatably. It is useful in school chemistry lessons on acids and bases, in biology and geography field work on ponds, rivers and soils, and in introductory college labs where each group needs its own meter.

• Class 7 and Class 10 science: comparing the pH of household substances and salt solutions.
• Field studies: checking the pH of pond, river or rain water on site.
• Agriculture and environmental courses: pH of soil suspensions.
• Group practicals: one meter per bench for acid-base investigations.

Standard Scope of Supply

The Checker Hand Digital Ph Meter is supplied as a single pocket meter as described above; any optional accessories are listed on the quotation. Buffer solutions for the two-point calibration are separate and can be added when you enquire.

Packing, MOQ and Lead Time

Pocket meters are often bought in class sets, and a quotation can be prepared for one unit or many. It details packing, delivery time and price for your number, with buffers, indicator papers or a bench meter on the same page if needed.

An Importer-Exporter Code registers Science Lab Supplies as an exporter, so it can ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Use the contact page for questions, the enquiry cart for a class-set request, and the lab tender page for government or institutional tenders of school chemistry lab equipment in India.

Frequently Asked Questions

How is the meter calibrated?
It uses manual two-point calibration: place the electrode in the first buffer and adjust one trimmer, then repeat in the second buffer with the other trimmer.

Why use a pH meter instead of litmus paper?
Litmus only shows acid or base, while this meter gives a number from 0.0 to 14.0, so students can compare how acidic or basic each sample is and reuse the meter many times.

Who supplies the Checker Hand Digital Ph Meter?
Science Lab Supplies supplies this pocket meter from Ambala, India, and quotes it singly or in class sets for schools, colleges and contractors.

Is it suitable for outdoor field work?
Yes. It is designed for education and field measurements, with a compact, rugged build that a student can carry to a pond, stream or garden plot.
