The HI-991301 high range meter offers great precision at high range to meet exacting requirements for testing pH, electro-conductivity, total dissolved solids and temperature. The HI-991301 high range meter offers great precision at high range to meet exacting requirements for testing pH, electro-conductivity, total dissolved solids and temperature. Designed for optimum consistency and reproducibility the HI-991301 portable high range conductivity meter offers a great range of user selectable features to deliver greater consistency and reproducibility. Different TDS factors ranging from 0.45 to 1.00 temperature coefficients (β) ranging from 0.0 to 2.4%.

The HI-12883 multi-parameter probe, incorporates a domed shaped pH bulb rated from 0 to 13 pH, a single junction Ag/Cl reference electrode with gelled electrolyte and a retractable cloth wick junction, a graphite EC/TDS cell, and a temperature sensor in one convenient, rugged polypropylene body. In addition, to ensure against interference from transient electrical noise to pH, a solid-state pre-amplifier is integrated into the probe. The probe is rated from 0 to 50°C.
