pH/mV/Temperature Meter Manufacturer,Supplier and Exporter in India

Product Code : EL-PM-2184
Jlab Export is a leading pH/mV/Temperature Meter Manufacturer,and suppliers in India

Small enough to hang on a lanyard, this waterproof tester measures pH, mV and temperature, and it floats if dropped in water. Automatic temperature compensation works from its own temperature reading. It calibrates at 4.00, 7.00 and 10.01 pH by push button, runs on four AAA cells and weighs 135 g with batteries.

Field Work and Classroom Practicals

The tester suits a water-quality walk around the school or college. Students calibrate it before leaving, then read the pH and temperature of tap water, a tank, a pond and a drain. The hold button freezes each reading so it can be written down after the tester is lifted out. Rinsing the tip from the Wash Bottle, Plastic between sites stops one sample carrying into the next.

For soil pH, students shake a soil sample with distilled water in one of the Beakers, let it settle and read the liquid above. They test the same sample with Soil pH Test Paper and compare the colour reading with the tester’s 0.01 pH figure.

Frequently Asked Questions

How often should the tester be calibrated?
Calibrate at the start of each day of use and after it has been stored for a while. Start with the 7.00 buffer, then use 4.00 for acidic samples or 10.01 for alkaline ones. Rinse the tip between buffers so they do not mix.

What do the hold and max/min functions do?
Hold freezes the reading on the display, so you can take the tester out of a stream or deep container and still read it. Max/min shows the highest and lowest values seen while the tester was on.

Can it be used in the rain or dropped in water?
Yes. It is waterproof to IP 57 and floats, so rain, splashes and an accidental drop into a pond are no problem. It is a hand-held tester, though, and is not meant to be left sitting in water.

How should the electrode be stored?
Keep a few drops of electrode storage solution in the cap so the glass bulb stays wet. Never store it dry or in distilled water, as both slow the response. Rinse after use before refitting the cap.

How long do the batteries last?
It runs on four 1.5 V AAA cells, and the display warns when they run low. Auto power-off after 10 minutes without use saves battery when the tester is left on in a bag.
