HI 9811-5 is a portable meter for field measurements of pH, conductivity and TDS that reduce the number of instruments required for water quality analysis. This versatile instrument is ideal for use in coolers and boilers, printing and agriculture. The rugged housing has been specifically designed to withstand the heavy demand of field application. HI 9811-0 measures pH from 0 to 14 with 0.1 resolution. The instrument also measures conductivity from 0 to 6000 µS/cm and TDS from 0 to 3000 mg/L. These ranges make HI 9811-0 perfect for use in boilers and cooling towers, as well as printing and agriculture. Calibration is simplified to one point for both pH and conductivity/TDS modes.
HI 9811-5 is equipped with Automatic Temperature Compensation (ATC). The Battery Error Prevention System (BEPS) alerts the user when low batteries could adversely affect your readings.
This portable meter uses the 4-in-1 replaceable probe HI 1285-0 for pH/EC/TDS, while the HI 9811-5 uses the HI 1285-5 probe, which measures pH/EC/TDS and Temperature.
