The Hanna Instruments HI 991003 is the first pH meter that can measure pH, pH-mV (to check the electrode status), ORP and temperature with only one probe.
An old, out of specifications pH electrode can result in erroneous pH measurements that can seriously damage the process. Hanna Instruments has solved this problem with the unique sensor check feature consists of a mV pH scale that shows the characteristics (slope and offset) of the sensor, allowing the user to determine if the electrode is in good condition.
The Hanna Instruments HI 991003 is protected in a waterproof casing for use in humid and wet environments. It also features a dual level LCD that displays pH or ORP and temperature. Automatic pH calibration can be performed with 5 standard buffers (for NIST or standard calibration).
