Conductivity measuring instrument GMH 5550

waterpH/oxidation-reductionuniversal

pH monitoring in aquaculture and aquariums, in drinking water supply and sewage treatment plants. Numerous agricultural applications (e.g. soil studies). Also suitable for quality assurance and control in industrial applications and in food production. Also suitable for medical, pharmaceutical and industrial laboratories. Designed for harsh environments: Impact-resistant and protected from water, the device even floats. ●Made in Germany ●Waterproof and impact-resistant ●GLP functions (Good Laboratory Practice) ●Large double display with backlighting ●High resolution (0.001 pH / 0.1 mV) ●including test report Additional functions Additional display for pH electrode and battery: Bar graph Backlighting: Adjustable lighting duration (off, 5 s..2 min.) Automatic temperature compensation: With temperature sensor connected and operating mode 'pH', automatic temperature compensation (ATC) takes place in the range of 0..150 °C. Manual entry is possible without a temperature sensor. pH calibration: optionally 1, 2 or 3-point calibration with characteristic curves for GREISINGER standard buffer (GPH or PHL) and buffer according to DIN19266 or with manual buffer input. With automatic buffer recognition, the temperature dependency of the buffer is compensated automatically. Permissible electrode data: Asymmetry: ±55 mV / gradient: 45..62 mV / pH, determination of the status of the pH electrode during calibration.
