Selectable temperature unit (°C or °F) meets different application requirements. Automatic electrode diagnosis shows zero point offset and slope of the electrode. Help message as a operational guide that helps you quickly begin using the meter. System menu allows setting the 10 parameters, including the pH buffer standards, number of calibration points, resolutions, stability conditions, hold function, etc. Reset feature automatically resumes all parameters back to factory default options. Expanded memory stores and recalls up to 500 readings. Built-in real-time clock stamps stored data to meet GLP standard. Stored data can be transferred into computer by USB communication interface. Multiparameter portable ion meter is equipped with a large backlit LCD display. Automatically recognize ion selective electrodes, does not need to specify type of ion. Relative and absolute millivolt measurements provide accurate ORP readings.
