The HI-991404 combines 4 meters into one easy to use wall mounting continuous indicator.

Featuring a large, dual-level, back-lit LCD display the meter can display the temperature of your solution together with the choice of either conductivity, pH or total dissolved solids (TDS).

It also features a reading stability indicator and a hold feature to make it easier to write down a particular reading.

Calibration and temperature compensation is automatic, while the conductivity and TDS conversion factors and temperature coefficients are user adjustable for specific application requirements.

Supplied complete with a non-clog double junction pH electrode and a rugged conductivity/TDS sensor, 12volt power transformer and buffer solutions 4 and 7 together with conductivity calibration solution.

For the full product specification please see the attached instruction manual.

The HI-991404 is supplied complete with:

  • HI-1293D pH eletcrode
  • Fixed HI-7630 probe
  • pH and EC calibration solutions
  • 12VDC adapter and instructions.
