Portable Water Hardness Meter LMPHM-601 comes with a solid-state ion selective electrode and LCD display. Manual temperature calibration improves the measurement accuracy of hardness meter. Stored data can be transferred into computer by using USB communication interphase. System menu allows setting the 7 parameters which includes the number of calibration points, stability condition, hold function, auto-power off. Stability indicator automatically indicate current measurement status.
