The HI991301 is designed to measure pH, conductivity (EC), total dissolved solids (TDS), and temperature with a single probe. From setup to calibration all operations are performed with just two buttons. The meter is waterproof and rated for IP 67 conditions.

 

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.

  • Automatic Temperature Compensation
  • Automatic one or two-point pH calibration
  • Easy-to-clean and maintain
