Description
Overview
GAOTek Portable pH meter also been called as Water Testing Device or Water Quality Testing Device, it’s the device that measure the value of pH, Cond. (Conductivity), Salinity, TDS and D.O. (Dissolved Oxygen) in liquid, which had been widely used by Aquaculture, Aquaponics or Fish Farm.
Features
- pH, Conductivity or Salinity or TDS, Dissolved oxygen & Temperature
- Handheld fashion housing with IP67 waterproof design
- Auto temperature compensation
- Auto ranging for conductivity measurement
- Multiple points calibration: 3 points for pH, 1 point for D.O.,4 points for conductivity
- Manually altitude lenity compensation for D.O. Measurement
- 99 points memories w/ recall function
- 1 hour auto power off
