7-in-1 Multi-Parameter Testing

Key features

pH: Measures the acidity/alkalinity of water (range: 0.01-14.00 pH) to monitor water balance.
TDS (Total Dissolved Solids): Detects dissolved substances in water (range: 0-10000ppm / 10.1-200.0ppt).
EC (Electrical Conductivity): Reflects the ion concentration in water (range: 0-10000us/cm, 10.01-19.99ms/cm, 20.1-400ms/cm).
Salinity: Tests salt content in water (range: 0-10000ppm / 10.1-200.0ppt / 0.00~25.00%).
ORP (Oxidation-Reduction Potential): Measures the redox potential of water (range: 0~±999mV).
Specific Gravity (S.G): Monitors water density (range: 1.000-1.222) for seawater and aquaculture applications.
Temperature: Displays water temperature in ℃/℉ (range: 0.1-60.0℃ / 32.0-140℉).

All-in-One Design: Eliminates the need for multiple separate testers, saving space and cost. 
High Precision Readings: Delivers fast, stable and accurate results with high-resolution digital display. 
Backlit LCD Screen: Clear readings even in low-light or dark environments. 
Easy Operation: Simple button controls for parameter switching, hold function and calibration. 
℃/℉ Switchable: Freely switch between Celsius and Fahrenheit units for temperature display.

 Portable & Compact: Pen-shaped design with lightweight body, easy to carry and use anywhere. 
Widely Applicable: Suitable for drinking water, aquariums, hydroponics, pools, seawater, aquaculture and laboratory use.
