Temperature measuring instrument GRYF 156

voltagefieldshape

Processor handheld measuring instrument for conductivity and temperature measurement GRYF 156 is a microprocessor-controlled, battery-operated measuring instrument. The instrument is designed to measure the specific conductivity of solutions 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 operated by four buttons that are similar to the PC: UP, DOWN, ESC, ENTER. The multifunction display (LCD) clearly displays all measured variables and other accompanying data and messages. The main measured value is shown on the display and, as a secondary, the accompanying temperature. Properties The conductivity measurement function is equipped with automatic temperature compensation (ATC), ie. when measuring the conductivity, the temperature used in the calculation of the resulting displayed value is measured simultaneously. 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. If the device is equipped with a voltage output, the measured data can be transferred to another device (eg a recorder). The device is powered by a 9V battery. A drop in its voltage is indicated by the "Bat" message. The automatic shutdown is set to 5 minutes.
