The digital salt-meter, ES-421 employs a funnel-shaped sensor to measure the salt content of a sample such as the dilute solution of soy sauce, ketchup, mayonnaise, worcestershire sauce, squeezed juice or pickles, etc. It only needs 1.0ml of sample. - Improved durability with titanium electrodes. - Stage is made out of SUS316L. - Equipped with a backlight for even brighter, easier to read display. - Equipped with an “Offset Function.” - The NaCl solution for calibration is different from the solution used for the former ES-421. Its concentration has been changed from 2.84% -->2.50%.
Scale: Salt concentration (g/100g) Temperature Method: Conductivity method Range: 0.00 to 10.0% Resolution: 0.01% for salt concentration of 0.00 to 2.99% 0.1% for salt concentration of 3.0 to 10.0% Accuracy: Displayed value ± 0.05% (for salt concentration of 0.00 to 0.99%) Relative precision ± less than 5% (for salt concentration of 1.00 to 10.0%) Ambient Temperature: 10 to 40°C (Automatic Temperature Compensation) Power Supply: 006P Dry battery (9V)
