Portable pH Meter with ph meter Sensor Check - Waterproof, portable, monitors water softening plants, swimming pools, plating bath waste water, potable water sanitizing processes
HI 991003 is the first pH meter that can measure pH, pH-mV (to check the electrode condition), ORP and temperature with only one probe. Since ORP measurements are strongly affected by pH level, HANNA instruments has developed the first meter that simultaneously measures both ranges. With all other instruments you need to switch the pH electrode with an ORP electrode (or vice-versa) and, therefore, it is impossible to have both measurements at the same time. HI 991003 is provided with our unique Sensor Check feature that allows the user to establish the status of the pH electrode before performing measurements. The Sensor Check feature consists of a pH-mV scale that shows the characteristics (slope and offset) of the sensor, allowing the user to determine if the electrode is in good condition. HI 991003 is protected in a waterproof casing for use in humid and wet environments. It also features a large dual level LCD that displays pH or ORP and temperature readings simultaneously.
HI 991003 is supplied complete with HI 1297D pH/ORP electrode with internal temperature sensor, pH 4 and pH 7 buffer sachets, HI 700661 electrode cleaning solution (2 x 20 mL), batteries, rugged carrying case and instructions.
