Designed to bring simplicity to environmental testing, the HI991300 pH/EC/TDS Meter is designed specifically for use in manufacturing and environmental testing protocols. The specialized electrode combines 3 sensors in a single rugged probe body featuring a polypropylene body, integrated temperature sensor, and cloth junction.
Designed to withstand the knocks, drops, and spills of real life, the new IP67 body ensures top performance in any environment. These meters are protected against dust and water intrusion from any direction.
Made to fit comfortably in your hand for on-the-go testing, the multilevel LCD display provides at-a-glance readings of pH and temperature from any angle and dual button operation streamlines the testing process for any user.
A Quick Connect DIN connector makes attaching and removing the probe simple and easy. The rubber coating protects the cable and provides a water-tight seal without twisting.
