DENSITY METER Features: Compact & lightweight enabling one-hand measurements Range: 0.0000-3.0000 Extremely user friendly menu Measuring time: 2-3 seconds Displays & logs temperature & specific gravity (S.G.) Power Supply: (2) AA batteries Accuracy: +/- 0.001 Automatically temperature compensated to 77F (25C) Suction nozzle: 7” Stores up to 1024 measurement results with time stamp Large LC display with backlight for clear visibility results Wireless infrared data interface for data exchange Calibration: With dry air or pure water   Tests lead-acid and Ni-Cad batteries The SBS-3500 is our newest portable specific gravity meter. It uses oscillating U-tube technology while measuring the density of your sample supplying results within seconds. It is able to communicate wirelessly with a printer or PC via the integrated IrDA interface. This is a great solution for battery system, general industrial, and laboratory applications.   Used for IEEE std. 450 battery testing. Predefined S.G. ranges increase speed when using this unit, yet allowing you to sample; measure, log, record & store compensate specific gravity readings and electrolyte temperature completing large 240 cell strings in minutes instead of hours. With +/- 0.001 % accuracy rating this is a quality instrument that can be used for a variety of different substances. Includes: Instruction manual Plastic syringes 2 mL Luer adapter 1/4” UNF (for syringe filling) Filling tube (standard 180 mm)
