Hanna HI991003 Portable pH Meter (pH/ pH-mv/ ORP/ Temp) Titanium Electrode
pH/ORP/Temperature Meter - HI991002
pH/ORP/Temperature Meter with Sensor Check - HI991003
The meter is supplied with: pH/ORP and temperature probe, pH 4.01 and 7.0 solution, electrode cleaning solution, batteries, instructions, and carrying case.
Electrodes are interchangeable exclusively with models included in other 99 Series instruments (HI12963, HI12923, HI629113, HI14143, FC10483, FC2143, FC2023, FC2323, FC2133).
The HI991002 meter measures pH/ORP and temperature.
The HI991003 is a portable pH/pH-mV/ORP and temperature meter with Hanna's unique Sensor Check™ feature, which allows the user to determine the electrode status at any time. The HI991002 and HI991003 meters are ideal for bathroom lining, wastewater, swimming pool, spa, and environmental water quality applications. HI1297D pH Electrode The pH/ORP/temperature probe (HI1297D) supplied with both meters features a pre-amplified titanium body. The titanium body is resistant to many aggressive products, including those used in plating and chemical manufacturing. The titanium body acts as an associated pin which, along with the built-in amplifier, helps reduce the effects of electrical noise in high-impedance pH measurements. The HI1297D electrode also features a removable fabric junction. The removable fabric junction allows for renewal of the junction. Simply pulling out about 2 mm of the junction reveals a new portion of fabric. Any obstruction that may be present... The present issue has been eliminated and the response time returns to normal, prolonging the useful life of the pH electrode.
- Titanium body resistant to aggressive chemicals.
- Removable fabric junction for any obstacle.
- Built-in temperature sensor for automatic temperature readings.
