Amtast inc mengeluarkan ph untuk laboratorium. Range yang diukur tergolong cukup lebar itu batas bawah ph= -1 dimana cocok untuk dipasaran ph yang tertinggi dijual HCL 35% atau sekitar 10 Molar sedang kan ph -1 = 10 Molar nilainya. Ph batas atas ph 15 dimana larutan NaOH tertinggi mempunyai ph = 15 dan molaritas 10 Molar dengan kelarutan 35%. Ph ini sangat cocok untuk laboratorium dengan tingkat keakuratan tinggi dan stabilitas tinggi. Ph ini termasuk pH Benchtop yang dapat diandalkan.
