What do our customers say?

Ion Science’s PhoCheck Tiger has impressed me with it’s reliability in humid environments. It’s a nice sized instrument, easy to use and is an easy piece of equipment to calibrate. It is an extremely good product, and the correspondence between Ion Science and myself has been prompt and precise.
