The Hanna Instruments HI991003 Waterproof Portable pH/ORP/Temperature Meter with Sensor Check is the ideal tool for manufacturing and environmental testing protocols. With a specialized probe that features a titanium body, integrated temperature sensor, and cloth junction, this pH/ORP meter brings simplicity to pH testing.
The meter offers an impressive ±0.02 pH accuracy and ±1 mV ORP accuracy, making it an extremely reliable option for direct pH and ORP measurement. The HI991003 comes with all the necessary solutions and batteries, making it effortless to get started and measure right away.
The HI991003 has exceptional specifications. Its pH range is -2.00 to 16.00 pH / -2.0 to 16.0 pH, with a pH resolution of 0.01 pH / 0.1 pH and pH accuracy ±0.02 pH / ±0.1 pH. It has automatic 1 or 2 point selectable buffer set calibration Standard: 4.01; 7.01; 10.01, or NIST: 4.01; 6.86; 9.21.
The ORP measurement range is ±825 mV (pH-mV), with an accuracy of ±1 mV (pH-mV). The temperature range is -5.0 to 105.0 °C/23.0 to 221.0 °F, with a resolution of 0.1 °C/0.1 °F and an accuracy of ±0.5 °C up to 60 °C; ±1.0 °C outside ±1.0 °F up to 140 °F; ±2.0 °F outside. It also offers automatic temperature compensation, which ranges from -5.0 to 105.0 °C/23.0 to 221.0 °F.
The HI991003 is powered by 1.5V AAA batteries (3 pcs.), and it consumes approximately 1400 hours of continuous use. It can operate within an environment of 0 to 50°C (32 to 122°F); RH max 100% RH max. 100%. The meter dimensions are 154 x 63 x 30 mm (6.1 x 2.5 x 1.2”), and it weighs 199 g (6.91 oz.) with batteries.
In addition to the above, each meter is supplied complete with the HI12973 pH/ORP/temperature probe with a titanium body and DIN connector with 1m (3.3’) cable, pH 4.01 & 7.01 Buffer sachet, HI700601 Electrode general cleaning solution (2 sachets), 100 mL beaker (1 pcs.), alkaline batteries: 1.5V AAA (3 pcs.), rugged carrying case, calibration certificate of meter, calibration certificate of probe, and an instruction manual. The HI991003 comes with a 2-year warranty, and it is recommended to use it with the HI12973 pH/ORP/temperature probe with a titanium body and DIN connector with the 1m (3.3’) cable, which is included.
