Waterproof pH, Temperature, Conductivity & TDS meter

The Hanna HI991300 and HI991301 are some of the most popular pH meters on the market for environmental field use. They are waterproof and durable for use in remote areas. The display shows temperature and either pH, Conductivity (EC) or Total Dissolved Solids (TDS) simultaneously. Easily and accurately measure environmental groundwater parameters.

For the rainy season

Now many states require that construction sites be tested for the character of runoff in pH and Turbidity. These tests should be taken when the rain event is generally greater than half inch(California). For actual requirements see local state mandates and USEPA Federal standard 180.1 and 40 CFR 450 A&B

HANNA INSTRUMENTS

Ready Function - To ensure your subsequent measurements are accurate, these meters will only allow calibration when the electrode has stabilized.

• Rugged, Waterproof Construction - The ABS housing provides the instrument with optimum protection from harmful environments.
• Dual Level Display with Graphic Symbols - A dual level LCD displays pH, Conductivity or TDS and Temperature at the same time. Graphic symbols guide the user throughout the calibration process.
• Comes with a one Year Warranty on the meter and six month warranty on the probe.
• Waterproof pH Meter
• HI991301 provides a wider range of EC and TDS
• See Specifications (Click)
• These pH meters should be calibrated just prior to use in the field.

HI 991300(1) is supplied with pH/EC/TDS/°C probe, batteries and instructions in a hard carrying case.
