Checker Hand Digital Ph Meter
Product Code : LSK-CL-10071
Checker Hand Digital Ph Meter (SKU LSK-CL-10071) is a pocket digital pH meter that reads 0.0 to 14.0 pH, designed for education 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 easy to use, rugged and practical for students. Schools, colleges, training institutes, tender contractors and distributors can order it through Science Lab Supplies, a chemistry lab instruments supplier working out of Ambala, India.
Specifications
The pocket meter's range, calibration and compensation details fill the rows below. Summed up, it shows pH to one decimal place across the full 0.0–14.0 scale, calibration is a manual two-point procedure in which each buffer reading is set with its own trimmer, and temperature compensation is also manual.

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, poured into a Chemical Glasses (Beaker) 50ml, against papers from the Test Paper Books.
- 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 such as the Acids and Bases Kit.
Standard Scope of Supply
The meter is supplied as a single pocket pH meter as described above; any optional accessories are listed on the quotation. Buffer solutions for the two-point calibration are not included and can be added to the same quotation when you enquire.
Packing, MOQ and Lead Time
A quotation can be prepared for one meter or for a full class set. 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. Teachers pricing a class set of school chemistry lab equipment in India can state the number on the contact page or in the enquiry cart; government and institutional tenders proceed through the lab tender page.
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 in Ambala, India, quotes this pocket meter for schools, colleges and contractors, as a single unit or as a class set with buffers and indicator papers.
Is it suitable for outdoor field work?
Yes. It is designed for education and field measurements, with a rugged build that a student can take to a pond, stream or garden plot for on-site readings.
