Introduction: This digital pen style PH meter is an ideal instrument for any aquarium, the fishing industry, swimming pools, school laboratories, food & beverage, etc. And, this Digital TDS Water Quality Tester is ideal for all basic water testing applications. This product is highly efficient and accurate due to its advanced microprocessor technology. Hold Function: stores measurements for convenient reading and recording. Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries. Measurement Ranges is between 0-9990 ppm, and from 0-999 ppm, the resolution is in increments of 1ppm; from 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking \'x10\' image. Applied range: the production and drinking of purified water, Electroplating liquid, Boiler water, Water in fish tank, Water of swimming pools, Photograph flushing fluid, Well water, Deep phreatic water, Laboratory, Aquaculture, Food processing, etc Features: 1.PH Tester With compact portable design This digital pen style pH meter is an ideal instrument for whatever you may need to test the pH levels. Excellent PH meter, very accurate and durable Measuring pH Range: 0.0 - 14.0 PH. Resolution: 0.1 PH Accuracy: in 0.1 pH (at 20 degree) Typical EMC DEV: 0.2 PH Relative Humidity: <95 degree Batteries: 3 x 1.5V (AG-13 Button Battery) Trimming: By Potentiometer Operating Temperature: 0 - 50 degree Meter comes with calibration screwdriver 2.TDS Tester Measures total dissolved solids (TDS) and temperature Measurement Range: 0-9990 ppm, 0 degree-99 degree (only TDS-3), 32- 212 (only TDS-3) Accuracy: 2% Full Scale: 1, 2 Digital Calibration (push button): Factory Calibrated 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 - 50 and it can be stored in the environment (- 30) 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 Specifications: Color: As picture shows Size: 14.2cm * 2.7cm * 1.5cm (pH Tester) Size: 14.5cm * 2.6cm * 2.0cm (TDS) Package weight: 6.90z/197g Accuracy: 0.1PH (at 20) Battery: 4 x 1.5V (AG-13 button battery) Relative Humidity: <95 The using life of battery: 700 hours Working temperature: 0 - 50 Power source: 2 x 1.5 V (button cell) Zero: Adjust by the compensate potentiometer Note: The value of TDS can show the content of impurities. The bigger of the value means that the content of impurities is larger; conversely, the content of impurities is small. The factors that affect the test value of TDS: the temperature of water (the TDS-3 tester cannot test the water with high temperature such as, boiled water). The flow velocity of water (the TDS-3 tester cannot be applied to test the flowing water) If the tester displays a flashing "X10" icon, multiply the reading by 10 Package Content: 1 x PH meter( include batteries) 1 x Calibration Screwdriver 1 x TDS Meter
