Portable conductivity meter GRYF 158

with automatic temperature compensation

Processor handheld meter for conductivity, pH and temperature measurement. GRYF 158 is a microprocessor-controlled, battery-operated measuring instrument. The device is designed to measure the specific conductivity of solutions, pH, electrical voltage and temperature. Its ergonomic shape allows one-handed operation, so it is suitable not only for laboratories, but also for field work and operations. The device is controlled by four buttons that are similar to the PC: use arrow keys, UP, DOWN, ESC, ENTER. The multifunction display (LCD) clearly displays all measured variables and other accompanying data and messages. The display shows the main measured value (conductivity, pH or mV) and the accompanying temperature variable. Properties The conductivity and pH measurement function is equipped with automatic temperature compensation (ATC), ie. when measuring conductivity or pH, the temperature used to calculate the resulting displayed value is measured at the same time. The Auto Temperature Compensation feature can be turned off. The four-wire conductivity cell with an integrated temperature sensor ensuring accurate measurement across all five ranges is standardly used to measure conductivity. The temperature compensation for conductivity can be selected according to the known temperature dependence of the measured sample in the range of 0 to 3% / °C or according to the dependence given in EN27888 for natural waters. Any combined pH electrode can be used to measure the pH. The ORP or other ISE measurement electrode may be connected to mV-meter input If the device is equipped with a voltage output, the measured data can be transferred to another device (eg a recorder)
