About GRYF HB
GRYF HB, spol. s r. o. is a manufacturer of multi-functional measuring instruments used for measuring electrochemical and physical values such as pH, temperature, conductivity, oxygen, redox potential.

The GRYF handheld meters are powered by a 9V battery and are controlled by a microcomputer. They are designed to measure the specific conductivity of solutions, to measure pH, to measure electrical voltage and temperature. Their ergonomic shape allows one-hand operation and is therefore suitable not only for laboratories but also for field work and operations. The devices are controlled by four buttons similar to the PC: up arrow, down arrow, ESC, ENTER. The Liquid Crystal Display (LCD) clearly displays all measured variables and other accompanying data and messages.
