The Hanna HI99301 portable high-range EC/TDS meter is engineered for diverse applications, including wastewater treatment, reverse osmosis, and HVAC systems. This durable waterproof instrument accurately measures high-range conductivity in mS/cm and total dissolved solids (TDS) in ppt. Its specialized HI76306 EC/TDS probe features an innovative two-ring design, resisting clogging and ensuring easy maintenance. With a built-in temperature sensor, the probe provides seamless Automatic Temperature Compensation (ATC) across a wide range of 0 to 60°C (32 to 140°F), guaranteeing precise readings.

Designed for convenience, the HI99301 meter comfortably fits in the palm of your hand, with a bottom probe connection that keeps the cable organized. The large, multi-level LCD simultaneously displays primary readings, temperature, and helpful calibration guides, while intuitive symbols and messages simplify operation for every user.

Key Measurement & Compensation Features:

Two-Ring EC/TDS Probe: The included HI76306 two-ring probe provides an exceptionally accurate solution for high-range EC and TDS readings. Its integrated temperature sensor enables automatic temperature compensation, vital for precise results.

Dual Measurement Modes: The HI99301 offers both EC and TDS measurement modes. Users can effortlessly switch between these with a simple press of the MODE button. EC measurements span from 0.00 to 20.00 mS/cm; TDS measurements cover 0.00 to 10.00 ppt.

Adjustable TDS Conversion Factor: Recognizing that the relationship between TDS and conductivity varies by solution, the HI99301 allows for a selectable TDS factor from 0.45 to 1.00, in 0.01 increments. This flexibility ensures the most accurate conversion for your specific sample.

Automatic Temperature Compensation (ATC): Temperature profoundly impacts conductivity and TDS readings. The HI99301's probe incorporates a built-in temperature sensor for automatic temperature compensation, ensuring consistent accuracy from 0 to 60°C (32 to 140°F).

Customizable Temperature Compensation Coefficient: Fine-tune your temperature compensation with an adjustable coefficient (β) from 0.0 to 2.4%/°C, in 0.1% intervals; this factor corrects the reading a set percentage % for each degree Celsius change in the sample.

Automatic One-Point Calibration: Streamline your setup with automatic one-point calibration using a standard EC or TDS solution. A 12.88 mS/cm standard is used for EC calibration, which will automatically calibrate TDS readings. Alternatively, if the meter is in TDS mode and set to a 0.5 conversion factor, a direct calibration in 6.44 ppt TDS calibration solution can be used.

Battery Error Prevention System (BEPS): Never worry about inaccurate readings due to low power. The BEPS actively monitors battery strength, alerting you when power is critically low and automatically shutting down the meter to prevent erroneous measurements.

Stability Indicator: The HI99301 features a convenient clock tag display that disappears only when your reading has achieved full stability, ensuring you capture accurate and reliable data.

The Hanna HI99301 is engineered for seamless operation and long-lasting performance in the field.

Intelligent Battery Management

Experience up to 500 hours of continuous use. A blinking warning symbol alerts you when battery levels drop below 10%, and the meter smartly shuts down to prevent any compromised readings.

Customizable Auto Shut-Off

Prolong battery life and enhance energy efficiency with selectable auto-off times of 8 or 60 minutes. For extended measurements, simply disable the feature for continuous monitoring.

Intuitive Dual Measurement Modes

Effortlessly switch between EC (0.00 to 20.00 mS/cm) and TDS (0.00 to 10.00 ppt) measurement modes, offering ultimate flexibility for diverse water quality analysis needs.
