HI991300 Water-resistant pH / EC / TDS and temperature Multiparameter

Article number: HI991300
Availability: Out of stock
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.
  • 3-in-1 probe measures pH, EC/TDS, and temperature.
  • Comes with all the necessary solutions and batteries- everything you need to get started measuring right away.
  • Perfect for water quality testing.
