Product Overview

• HI991301

• High-range water quality meter pH: 0.00 to 14.00 pH, temperature: 0.0 to 60.0 °C, 32.0 to 140.0 °F EC: 0.00 to 20.00 mS/cm, TDS: 0 to 2000 ppm (mg/L)

• Multi-level LCD allows manual testing anytime, anywhere, with pH and temperature or EC/TDS and temperature readable at a glance from any angle, automatic calibration recognition, temperature compensation, and two-button operation simplifies the testing process for any user. The quick-connect DIN connector makes connecting and disconnecting the probe simple and convenient. The rubber coating protects the cable and provides a waterproof seal without twisting; suitable for providing laboratory-grade measurement results even in harsh environments

• New exterior design, extra-large dual-line screen display, on-screen calibration procedure prompts;

• User-friendly operation interface, stability indicator, two-button simple operation, convenient to use;

• Simultaneously measures and displays pH/(EC/TDS) and °C, with quick switching between pH, EC, and TDS;

• 1-2 point automatic pH calibration recognition, with 2 sets of built-in pH standard calibration points; pH4.01, 7.01, 10.01 and pH4.01, 6.86, 9.18

• Conductivity and TDS single-point automatic calibration recognition, with built-in standard points;

• EC: 1413 or 12880μS/cm; TDS: 1382, 1500ppm or 6.44 ppt

• Automatic or manual temperature compensation, ensuring measurement precision and accuracy in different environments;

• Battery replacement is simple and quick, BEPS low-battery error-prevention system avoids incorrect measurements;

• Suitable for providing laboratory-grade measurement results even in harsh environments.

• Meter HI991300 or HI993301, HI1288 dedicated built-in temperature sensor pH-EC-TDS multiparameter electrode, pH-conductivity standard buffer solution kit, Chinese and English instruction manual

• The HI991301 is designed to measure pH, conductivity (EC), total dissolved solids (TDS), and temperature using a single probe. From setup to calibration, everything can be done with just two buttons. The meter is waterproof with IP 67 protection class.

• The HI12883 pre-amplified multiparameter probe features easily cleanable sensors and a renewable cloth junction to extend probe life. To prevent interference from transient electrical noise, a solid-state amplifier is integrated into the HI12883.

• User-selectable features include different TDS factors from 0.45 to 1.00 and a temperature coefficient (β) range from 0.0 to 2.4% for greater consistency and repeatability. Standardized buffer recognition values are also selectable.

• These instruments fit easily in the palm of your hand, and the bottom probe connection ensures the electrode cable does not get in your way. The large multi-level LCD displays the primary reading, temperature, and calibration
