2 pH Meter
2 pH Meter (Product Code: SLE/ME/48) is a pocket-sized pH meter used to check the acidity or alkalinity of solutions in school laboratories, field studies and small testing rooms. Just 160 mm long, it reads pH 1 to 13 with 0.01 pH resolution and ±0.01 pH accuracy — the accuracy of a bench meter — and its replaceable electrode has a built-in amplifier. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as one of the lab instruments it supplies across India and abroad.

What Is the 2 pH Meter Used For?
A pocket pH meter lets students move beyond indicator colours to real numbers. The 2 pH Meter can follow pH during an acid–alkali neutralisation, test rainwater, pond and tap water on a field trip, check soil-water extracts in agriculture and environmental projects, and compare household substances in an introductory acids-and-bases lesson.
Calibrate at two points with standard buffers, using the small screwdriver supplied, before each session. Automatic temperature compensation from 0 to 70 °C corrects readings for sample temperature, but the meter itself should be used within its 0 to 50 °C operating range. Rinse the electrode after every sample and replace it when readings become slow or unstable — the electrode is designed to be changed.
What to Specify When Ordering
- Number of meters needed per class or field group.
- Whether spare replaceable electrodes should be quoted with the meters.
- Whether spare 675H or A76 button cells and calibration buffers are needed.
Supplier
Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, Haryana, supplies the 2 pH Meter to schools, colleges, agricultural and environmental-science departments, and dealers. Replacement electrodes, cells and buffers can be requested on the same enquiry as the meters. More about the company is on the ScienceLab company profile.

Frequently Asked Questions
What is the range and accuracy of the 2 pH Meter?
The 2 pH Meter measures from pH 1 to 13 with a resolution of 0.01 pH and an accuracy of ±0.01 pH, giving pocket-meter convenience with the accuracy normally expected from a bench meter.
How is the 2 pH Meter calibrated?
The 2 pH Meter uses dual-point calibration. It is supplied with a small screwdriver for making the calibration adjustment, normally carried out with two standard buffer solutions before a set of measurements begins.
Does the 2 pH Meter compensate for temperature?
Yes. The 2 pH Meter has automatic temperature compensation from 0 to 70 °C, while the meter itself is designed to operate between 0 and 50 °C, so readings stay reliable in normal laboratory and outdoor conditions.
Can the electrode of the 2 pH Meter be replaced?
Yes. The 2 pH Meter has a replaceable electrode with a built-in amplifier, so a worn electrode can be changed instead of replacing the whole meter. Ask us to quote spare electrodes with your order.
What batteries does the 2 pH Meter use?
The 2 pH Meter is powered by three 1.5V button cells of type 675H or A76. Batteries are supplied with the meter, together with a small calibration screwdriver and a carrying case.
Who supplies the 2 pH Meter?
The 2 pH Meter is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges, laboratories and dealers in India and international markets. Quotations are sent on request through the contact page.
