➤ Product Introduction
Turbidity is one of the primary indicators for evaluating water cleanliness. According to metrological regulations, the legal turbidity standard adopts turbidity standard reference materials, which must be diluted with zero-turbidity water to reproduce the accuracy of the reference material.
The TUS-84 turbidity water calibration device is primarily a mobile, convenient "zero-turbidity water" preparation unit. Designed in accordance with the preparation requirements of the "Verification Regulation of Turbidimeters - JJG-880-2006," it not only meets on-site "zero-turbidity water" sample preparation needs but also allows the "zero-turbidity water" to be delivered directly via tubing to the inlet of the instrument under test, preventing secondary contamination from exposure to ambient air or impurities. It not only satisfies user field applications but also serves as essential equipment for metrology institutions performing on-site calibration services.
Built with a high-strength portable protective instrument case as the carrier to ensure stability, the device features quick-install membrane modules to maximize field personnel efficiency and minimize operational steps. Considering uncertain application scenarios, the unit is equipped with a built-in lithium battery. The system integrates technologies such as battery management and variable-frequency flow control, making it a rare mobile, tool-based device in the turbidity product verification market both domestically and internationally.
➤ Key Performance Features
● Built-in lithium battery enables a mobile, vehicle-mounted zero-turbidity water preparation system, facilitating on-site zero-turbidity water production;
● Lithium battery power supply system supports continuous operation for nearly 15 hours on a full charge;
● Equipped with a variable-frequency power unit, suitable for automatic extraction from pressurized water sources or water tanks;
● Features variable-frequency flow rate adjustment function with digital indication of the zero-turbidity water preparation rate;
● Comes with quick-install membrane module assemblies; membrane replacement is completed with a "pull and twist" action;
● Constructed with purification-grade engineering materials, offering multiple connection options including ferrule-type, quick-connect, barb-type, and threaded fittings;
● High-strength instrument case with support rods and caster pull handle, facilitating on-site operation and mobility;
● RO water, distilled water, or purified water sources are recommended to ensure water output and longevity;
● If tap water is used as the source, impurities in the water will accelerate the consumption of filter cartridge service life.
➤ Typical Applications
● For turbidity background detection and standard solution preparation;
● Suitable for evaluation and metrological verification of turbidity instruments in laboratory and online scenarios;
● Applicable for calibration and metrological inspection of turbidity products in industrial field settings.
