Features & Applications:

This Hanna pH / conductivity / TDS meter measures all three at the same time which reduces the number of instruments you take into the field. No probe changes are required when switching between these parameters using the newly designed four-in-one replaceable HI 1285 probe. The probe utilizes a temperature sensor to provide readings that are automatically compensated for temperature. The pH electrode features a fiber junction and gel electrolyte for faster response and reduced contamination. 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.

Powered by a 9V battery (included), the meters are equipped with BEPS (Battery Error Prevention System) to avoid errors due to low battery power. Battery provides approximately 150 hours of continuous use. Comes complete with the HI 1285 probe with 1m cable, pH 7 buffer (20mL), 1413µS/cm and 1382ppm calibration solutions (20mL each), 9V battery and instructions. 7.3" x 3.2" x 1.8". Specifically engineered for water-quality applications, the pH electrode features a fiber junction and gel electrolyte that provides faster response and reduced contamination.
