Hanna Instruments HI99300 Portable Low Range EC/TDS Meter

Intelligent Battery Management

Power your testing for up to 500 continuous hours. A low battery warning alerts you before critical levels, and the meter automatically shuts down to prevent inaccurate readings from insufficient power.

Customizable Auto Shut-Off

Extend battery life and ensure safety with selectable auto-off times of 8 or 60 minutes, or disable it for continuous monitoring during long-term measurements.

Dual Measurement Versatility

Seamlessly switch between EC (0 to 3999 µS/cm) and TDS (0 to 2000 ppm) measurement modes with a simple press of the MODE button, offering flexibility for various applications.

Robust and Reliable Construction

The HI99300 boasts an IP67-rated waterproof body, engineered to withstand demanding environments, protecting against dust and water ingress from any direction for consistent performance.

Ergonomic Portable Design

Designed for comfortable handheld use, the meter features a clear, multi-level LCD that provides easy-to-read EC/TDS and temperature values from any viewing angle. Simple two-button operation streamlines testing.

Effortless Probe Connection

The Quick Connect DIN connector allows for swift and secure attachment and removal of the EC/TDS probe. The protective rubber coating ensures a watertight seal without the need for twisting, enhancing probe and cable durability.

Hanna Instruments HI99300 Quick Connect Probe

Ensure accurate low-range EC and TDS measurements across diverse applications like wastewater treatment, reverse osmosis, and HVAC with the HI99300's specialized and replaceable HI763063 probe.

Precise Two-Ring Probe Technology

The HI763063 probe, included with the HI99300, utilizes a two-ring sensor design to deliver accurate and reliable conductivity and total dissolved solids readings in low concentration samples.

Integrated Temperature Compensation

The built-in temperature sensor within the probe ensures fast and accurate temperature-compensated measurements, even when dealing with rapid temperature fluctuations in your samples.

The HI99300 Low Range EC/TDS Meter kit provides everything necessary for immediate and accurate conductivity and total dissolved solids testing.

Included Calibration Standards

The meter is supplied with one sachet each of HI70031 (1413 µS/cm) and HI70032 (1382 ppm) conductivity calibration standards, ensuring accurate calibration for reliable measurements right from the start.
