Aquarium PH TDS Meter Tester Portable Pen Digital High Accurate Filter Measuring Water Quality Purity Test Tool | Дом и сад

PH meter features:

This digital pen style pH meter is an ideal instrument for aquarium, fishing industry, swimming pool, school laboratory, food & beverage etc. With calibration screwdriver and 2 sachets of buffering solution for calibration. Built with Automatic Temperature Compensation (ATC).Tester with ATC will automatically measure the water temperature compensation to 25 degrees state,while ordinary pen should de in the water temperature of 25 degrees around the state more accurate. PH meter calibration standards: The pH electrode into the pH value of 6.86 (25oC under standard mixed phosphate buffer solution, and gently shake. With a small screwdriver adjust the calibration potentiometer until the display value and the standard buffer solution at ambient temperature ph values. The electrodes into pH4.00 stupid phosphorus or potassium acid borax pH9.18 standard buffer solution. After about two minutes or so. Shows the pH value of the buffer value is compared to the error should be within the allowable range.
   
Measuring pH Range: 0.0-14.0 pH Resolution: 0.1 pH
Accuracy: 0.1 pH 
Operating Temperature: 0 - 50oC (32-122F)
Size: 142mm x 29mm x 15mm
Battery: 3x1.5v (AG13 button battery) (not included)
   

TDS tester Features:

Shuts off automatically after 10 minutes of non-use. Automatic temperature compensation function: it can automatically change the displayed value into the value of 25. High accuracy: Use the Titanium alloy probe which can avoid magnetic disturbance to test water and only has the error ( 0.1). Measuring temperature: 0 - 50oC and it can be stored in the environment (- 30oC). LCD display screen: Big LCD display screen which has great waterproof performance and let you easily read the displayed value. Fast measuring: can measure once in five seconds. Dual Range: Measures form 0-999ppm, with a resolution of 1ppm. From 1,000 to 9,990ppm, the resolution is 10ppm, indicated by drinking x 10image,multiply the reading by 10.
   
Range: 0-9990ppm Accuracy: +/- 2% Temperature range: 0-50oC(32-122F) Size: 155mm x 31mm x 21mm Battery: 2 x 1.5V Button Cell battery(not included) Order Notice:
                PH meter: In the following cases, PH meter must be recalibrated: 1, After calibration has been used (or place) for a long time. 2, Frequent use of special electrodes. 3, Accuracy requirements are relatively high.
         
TDS tester:           Do not drop the entire TDS meter in water of dip beyond the maximum immersion level. 
The TDS-3 tester cannot test the water with high temperature such as, boiled water.
The TDS-3 tester cannot be applied to test the flowing wate.
