Frequently asked questions

What does IP67 waterproof mean?

IP67 means the meter is dust-tight and can be immersed in water for a limited time. This model also floats on the water surface, which makes it convenient for measuring in tanks and ponds.

What is the pH range and accuracy?

0.0 to 14.00 pH with 0.01 pH resolution and ±0.05 pH accuracy.

How do I calibrate it?

It supports 1 to 3 point auto calibration with USA buffers of pH 4.01, 7.00 and 10.01. Rinse the electrode, dip it in each buffer in turn and let the meter recognise the buffer automatically.

Does it correct for temperature?

Yes. It has temperature compensation and also displays temperature, over 0.0 to 99.9 °C with 0.1 °C resolution and ±0.5 °C accuracy.

Can I replace the electrode?

Yes. The electrode module is replaceable, so you can fit a new one when the electrode wears out instead of buying a new meter.

What battery does it use?

Four 1.5 V coin cell batteries.

How long before it switches off?

It turns off automatically after 6 minutes if not in use.

What temperatures can it be used in?

The ambient temperature range is 10 °C to 50 °C. The meter measures sample temperatures up to 99.9 °C.

What is the difference between the TPH2 and the TPH1?

The TPH2 is waterproof (IP67), floats, has a replaceable electrode, a double-line LCD, 1 to 3 point calibration and temperature compensation. The TPH1 is a simpler 1-point tester.

Can I get a GST invoice and a bulk or institutional quotation?

Yes. Labmart supplies colleges, hospitals, pharma companies and government laboratories across India and issues a GST invoice with every order. For bulk or institutional quantities, send us the quantity you need and we will share a quotation.
