7 in 1 PH/TDS/EC/ORP/S.G/Salinity/Temperature - with backlight

Features:It can measure PH / TDS / EC / ORP / S.G/seawater specific gravity / temperature. The measurement range is large and wide and can measure freshwater salinity and sea salt.This product can detect the salinity of edible salt. At the same time it can detect the salinity of seawater. Food salinity measuring range: 0.00-25.00% seawater salinity measuring range: 10.1-200.0ppt.IP67 is an international waterproof and dustproof certification. Protection against dust intrusion short-time immersion.Portable TDS meters can be carried anywhere to measure water quality such as tap water RO system water aquarium seawater pool water.The automatic power-off function turns off the power after 5 minutes without any operation to save power. Employs a fully transparent liquid crystal (LCD) to display 4-digit values and the corresponding physical quantity units.Specifications:Model: C-600A(with backlight) / C-600 (optional)EC: Measurement range: 0 to10000uS/cm 10.01-19.99ms 20.1-400mS/CMResolution: 1 uS/cm; 0.1 mS/CM;Accuracy: 2% of readingTDS: Measurement range: 0 to 1000ppm 1000ppm to 10000ppm 10.1 to 200.0pptResolution: 1ppm;; 0.1pptAccuracy: 2% of readingSalinity: Measurement range: 0.00 to 25.00%Resolution: 0.01%Accuracy: 0.01-5.00% (0.1%) 5.10-25.00% (1%)PH: Measurement range: 0.01-14.00pHResolution: 0.01pHAccuracy: 0.05pHORP: Measurement range: 0~999mVS.G:Measurement range: 1.000~1.222Working environment: 0 to 60.0 C (32.0-140 F); RH 100%TDS factor: 0 .4to 1.0Temperature range: 0.1-60.0 C 32.0-140 FTemperature accuracy: 0.5CTemperature resolution: 0.1 C / FPower source: 3x1.5LR44 ( not included )Display size: 33*24mmSize: 183*37*37mm (7.2*1.5*1.5in)Weight: 105g (3.2oz)Package List:1 * 7 in 1 meter1 * manual in English3 * buffer power1.this item comes without retail box2.Precautions Always clean the electrode after each use.3.If the pH calibration does not identify the solution the electrode is broken.
