Digital Water Tester 5 In 1 Multi-function Meter, No Backlight

[High-precision] The high-precision algorithm chip and electrode of our digital water pH tester ensure accurate and fast response. When the measured value is stable, just press the HOLD/TEMP key to lock the measured value and take it out for viewing. This is very simple.[Two salinity meters] The digital pH meter can detect the salinity of edible salt. At the same time, it can detect the salinity of seawater. Food salinity measurement range: 0.00-25.00%, sea water salinity measurement range: 10.1-200.0ppt[Automatic shutdown function and large-screen display] The PH tester has a LCD, which can help you clearly see the measurement results under any circumstances. The automatic shutdown function can turn off the power after 5 minutes, saving power without any operation. A completely transparent liquid crystal (LCD) is used to display the 4-digit value and the corresponding physical quantity unit.[Automatic temperature compensation] Temperature may affect the reading level. The range of the digital hydroponic pH meter is 0C-60C (0-140F). Automatic temperature compensation can ensure you get better readings, so you You can safely test in any environment.Product parametersConductivity test range: 0 to10000uS/cm 10.01-19.99ms 20.1-400mS/CMResolution: 1uS/cm; 0.1mS/CMAccuracy: 2% of readingTds test 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 test range: 0.01-14.00pHResolution: 0.01pH Accuracy: 0.05pHTemperature Compensation: Automatic Temperature Compensation (ATC)Working environment: 0 to 60.0C (0-140F); RH 100%TDS factor: 0.4to 1.0Temperature range: 0.1-60.0 32.0-140Temperature accuracy: 0.5Temperature resolution: 0.1C/FAuto power off: about 5 minutes 3x1.5LR44Dimensions and weight: 183 x 37 x 37mm(7.2 x 1.5 x 1.5inch)/90g(3.2oz)Waterproof grade: IP67Power consumption: 2.9 mA, power consumption is 0 when offThe accuracy is relatively accurate within 150ppt, and the deviation above 160ppt is relatively large.Note: After each use, be sure to clean the electrodeDisplay: No Backlightcolor:As shownMaterial:plasticPackage Contents:1 x water quality testerOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
