pH Meter LBN-PH181 is a bench top device which has a water-resistant keypad and a large dual-display to read both parameters and temperature at once. The temperature compensation mechanism is automatic/manual and operates between -10°C to 110°C. View active pH and temperature calibration logs in real time, and record up to 1000 data sets using the large LCD screen and transferable data loggers. Working temperatures range from 5 °C to 35 °C with an average humidity of 85%, ensuring error-free measurements.
