Portable Conductivity Meter HI99300

All prices are VAT excluded and without shipping costs, unless otherwise stated.

HI99300 and HI99301 are conductivity, total dissolved solids and temperature meters designed to meet the requirements encountered in manufacturing and environmental testing protocols. To increase precision, each of these models feature a different conductivity range, to cover applications from purified to brackish waters.

The supplied multi-parameter probe, HI763063, includes EC/TDS and temperature in one convenient, rugged probe. Other user selectable features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients (β) from 0.0 to 2.4% for better solution temperature compensation.

Portable Conductivity meter -EC/TDS and Temperature

Simultaneous EC/TDSand temperature measurements on a large dual-line LCD display
• User-friendly
Design With only two buttons, meter operation could not be simpler. Two buttons allow you to quickly adjust settings, select the measurement range, and choose calibration buffer sets.
• Durable IP67 waterproof casing
Designed to withstand the knocks, drops, and spills of real life, the new IP67 body ensures top performance in any environment. These meters are totally protected against dust and water intrusion from any direction.
• Watertight Connection
A Quick Connect DIN connector makes attaching and removing the probe simple and easy. The rubber coating protects the cable and creates a sealed connection for added reliability

• Large LCD
 A multilevel display provides ata-glance readings of your most important numbers from any angle.
• HOLD button
Freezes the reading on the display
• Selectable temperature unit (°C or °F)
• Battery life indication and low battery detection
