The HI1288 pre-amplified multiparameter probe features an easy-to-clean sensor and a cloth junction that can be renewed to increase the life of the probe. To ensure against interference from transient electrical noise, a solid-state amplifier is integrated into the HI1288.
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 greater consistency and reproducibility. Standardized buffer recognition values are also selectable.
These instruments easily fit in the palm of your hand and the bottom probe connection ensures the electrode cable doesn’t get in your way. The large, multi-level LCD displays the primary reading, temperature, and calibration guides simultaneously.
