pH meter, 5-in-1 controller for pH/TDS/EC/ORP/temperature, water quality tester for hydroponic ponds and drinking water aquariums

General Description: The 5-in-1 pH meter is a multifunctional pen-shaped testing device for measuring water quality in various environments such as swimming pools, aquariums, and hydroponic systems. It measures pH, TDS solubility, electrical conductivity (EC), salinity, and temperature, and delivers accurate and reliable results thanks to its waterproof design and five integrated functions. Technical Specifications: Conductivity measurement range: 0–10,000 µS/cm, 10.01–19.99 mS/cm, 20.1–400 mS/cm; Conductivity resolution: 1 µS/cm, 0.1 mS/cm; Conductivity accuracy: ±2% of the reading; TDS measurement range: 0–1,000 ppm, 1,000–10,000 ppm, 10.1–200.0 ppt; TDS resolution: 1 ppm. 0.1 ppt TDS Accuracy: ±2% of reading Salinity Measuring Range: 0.00 to 25.00% Salinity Resolution: 0.01% Salinity Accuracy: 0.01–5.00% (±0.1%), 5.10–25.00% (±1%) pH Measuring Range: 0.01–14.00 pH pH Resolution: 0.01 pH pH Accuracy: ±0.05 pH Temperature Compensation: Automatic Temperature Compensation (ATC) Temperature Range: 0.1–60.0 °C (32.0–140 °F) Temperature Accuracy: ±0.5 °C Temperature Resolution: 0.1 °C/°F Automatic Shut-Off: approx. 5 minutes Size: 183 x 37 x 37 mm (7.2 x 1.5 x 1.5 in) Weight: 90 g (3.2 (oz) Packaging size: 236 x 80 x 50 mm Packaging weight: 170 g Display: Backlit Waterproof rating: IP67 Power consumption: 2.9 mA (0 mA when off) Application: To ensure accurate results, it is recommended to clean the electrode after each use. This meter is ideal for measuring the salinity of fresh and salt water and is perfect for aquariums and hydroponic systems. Further information: The accuracy is relatively high below 150 ppt; the deviation is greater above 160 ppt. The measurable salinity in seawater is usually given in grams per kilogram of water. The measuring range for freshwater is between 0.00 and 25.00% with an accuracy of 0.01–5.00% (±0.1%) and 5.10–25.00% (±1%), respectively.
