Customer Message - Disruption due to Coronavirus *** Updated 29/03/20 ***

We are currently operating with a minimum of essential staff. Whilst we continue to dispatch orders, we would be grateful if customers would bear with us. Orders are being dealt with on a strict first come first served basis, but we cannot guarantee dispatch or delivery will meet our usual standards.

If ordering from us, please note:
  • 1. Our couriers are suffering from higher demand and are struggling to meet their delivery targets. We therefore cannot guarantee delivery service lead times, particularly if you choose the Overnight or Express options.
  • 2. We are no longer able to process orders for bespoke items, including garment embroidery.
  • 3. We are unable to answer telephone enquiries or take telephone orders. If you need to contact us, please email.
We would like to wish all our customers the very best in these difficult times and hope you manage to stay safe and healthy.

pH Testers and pH Meters

The Thermometer Superstore range of pH testing equipment is easy to use and accurate. There is no need for litmus paper, just dip the pH tester into a liquid and read off from the pH level from the display. You can tell in an instant whether a solution is acid or alkaline.

The pH Testers we offer have been chosen for their rugged construction and value for money. They range from low cost, simple, "needle pointer" instruments that are ideal for the keen gardener, to high specification, high accuracy digital testers from leading suppliers such as Hanna.

PH meters and pH testers are suitable for testing industrial processes, swimming pool water, aquariums, hydroponic applications or for use in school laboratories.

pH meters make pH testing extremely easy. We also supply the buffer solutions for calibrating and storing the pH testers
