The Ultimate in Hygiene Control
Dirty debris…foul odor…bacteria...(!) Even to the slightest degree, you hate to imagine these things affecting your equipment, dont you? Now set your mind at ease. Lets examine the SJ-WP series piece by piece so you can see why its sanitation standards can be perfectly assured
Externally Mounted Load Cell (Weight Sensor) This novel design allows the device to be completely sealed for watertightness without compromising the weighing speed and stability due to up and down movement of the load cell changing the air pressure inside. As a result, the stabilization of the SJ-WP series can be as fast as 0.5 seconds.* 2
Stainless Steel (SUS304) Weighing Pan The surface is resistant to scratches and wear, and is easy to keep disinfected
Transparent Panels Around the Load Cell The panels hanging from the pan support shield the load cell from debris to keep it clean as well as away from drafts to ensure stable weighing. Since they are transparent, the degree of contamination inside is always visible.
Quickly Removable Pan Support When cleaning is required, you can remove the pan support simply by loosening the four screws using a coin, etc.
Integrated Overload Protection Mechanism The load cell incorporates a stopper and requires no external components for overload protection. The area around the load cell is therefore unobstructed and easy to keep free from debris.
Submersible, IP67 Dust and Waterproof Besides using water from a hose, it is even possible to soak the scale directly in water with ph-neutral detergent for thorough washing.
Large LCD Display (26 mm Character Height) with White Backlight
The large-sized characters make the weight values easy to read. With the clear white backlight, the display provides excellent visibility even in a dimly-lit area.
Bright and Multi-Colored 5-Step LED Comparator Lights
The clearly-discernible LED helps you judge the results of check weighing instantly and accurately. Comparison can be made in three levels, five levels, or even seven levels, with no light indicating either end of the continuum
Auto-Tare Function
The scale can perform tare automatically when the weight reaches the set target range, saving you from the hassle of pressing the TARE key each time for consecutive measurements.
Negative Comparison
The comparator also functions in negative values. By using this and the auto-tare function together, you can perform “take-away” check weighing
Unparalleled, 5000-Hour Continuous Operation With Normal Batteries
Based on regular use of 8 hours a day, 5 days a week, a single set of batteries will last approximately 2.5 years
Auto Power OFF Function
To avoid wasting power, the scale turns the power off automatically when it is inactive for a set period (5 to 60 minutes) of time.
Battery Indicator
The scale displays the remaining battery level so that you can prevent the batteries running out unexpectedly while in use.
Other Features
Four selectable weighing resolutions: 1/3,000, 1/6,000 (or 1/7,500), 1/12,000 (or 15,000), and 1/30,000
Touch sensitive, capacitive keys covered with hard plastic, which prevents surface rupture and thereby ensures permanent waterproofing
Multiple weighing units: gram, kilo gram, pound, ounce, troy ounce, pound-ounce, tael (Singapore/HK jewelry/Taiwan), tola, and Newton
Counting function to calculate and display the number of pieces based on their individual unit weight
