Specification: Condition: 100% Item Type: Food Salinity Tester Material: ABS, Copper Model: NS01 Battery Adaptation: 4 x LR44(AG13) Button Battery (Battery Not Included) Test Standard: The temperature of the tested object is 60-80℃, and test is 2-10 seconds (commonly used salty standard, theory: 993 grams of water and 7 grams of salt give a value of 0.8-1.0) Power Input: 4x1.5=6V Working Current: Maximum 20mA (LED All On) Measuring Range: 0.3%-2.0% Applicable Temperature Range: 60℃-80℃ Calculation Formulas: Salt Content = Total Mass x Concentration (For Example: If the total mass of 1 cup of solution is 150g, the concentration is 0.5% 150g x 0.5%= 0.75g) Size: Approx. 212x24.8x15.4mm / 8.3x1.0x0.6in Function Description: 1. Probe: test salt concentration 2. The 7 red LEDs respectively indicate the salt concentration: 0.3% (moderate standard) 0.6% (1.5 times salty) 0.8% (2 times salty) 1.0% (2.5 times salty) 1.3% (3 times salty) 1.7% (4 times salty) 2.0% (5 times salty) 3. 1pcs green LED for power indicator 4. ON button: Pr the button and hold it down, the test can be performed when the power is turned on, and the test will stop when it is released. Instructions for Use: 1. Check whether the salt tester probe is clean. If it is not, please clean it with a neutral detergent. 2. The temperature of the soup is between 60-80℃, insert the probe into the test object, about 2 second Package List 1 x Food Salinity Tester (Battery Not Included)
