A&D EK-15KL precision bench scale provides 15 kg capacity with 0.1 g readability across the full weighing range, a combination designed for bulky or relatively heavy loads that still require fine displayed increments. The MNM SKU EK-15KL-RB is specifically listed with the optional rechargeable battery installed, making this configuration portable as well as precise.
Why 15 kg × 0.1 g is unusual
Many scales trade resolution for capacity. EK-15KL maintains 0.1 g readability from zero through 15 kg instead of switching to a coarser range at higher loads. That gives 150,000 displayed intervals across the nominal metric range, which is useful when a heavy container and relatively small additions must be observed on the same instrument.
Large stainless platform
A&D specifies a 300 × 210 mm pan, approximately 11.8 × 8.2 inches, with a SUS430 stainless-steel pan cover. The larger footprint supports containers, bulk samples, kits and production objects that do not fit comfortably on laboratory balance pans.
Repeatability and linearity
Published specifications include 0.3 g repeatability and ±0.6 g linearity. Those values are more informative for process planning than readability alone. A 0.1 g display digit does not mean the total uncertainty of every result is ±0.1 g; environment, calibration, placement and procedure also contribute.
Counting, percent and comparator modes
Counting mode supports sample sizes of 5, 10, 25, 50 or 100 pieces and A&D's ACAI function for improving average piece weight. Percent mode can support formulation or comparison to a reference mass. HI/LOW/OK comparator functions help operators judge whether a load falls inside programmed limits. These modes are tools for process control, not substitutes for validating the underlying measurement method.
RS-232C and data output
RS-232C is standard on the EK-L series for output to a PC, printer, data logger or compatible controller. A&D also lists GLP/GMP/GCP/ISO-oriented output capability. If records drive quality decisions, define units, timestamps, operator identification, device ID and review controls in the complete workflow.
Rechargeable battery configuration
The MNM EK-15KL-RB listing includes the optional rechargeable battery installed. A&D publishes approximately 100 hours of operation on a full charge at 25°C with the backlight off. Real runtime depends on battery condition, backlight use, temperature and age, so establish a charging routine for critical mobile workstations.
Calibration and routine verification
The MNM specification lists a 15 kg calibration weight for this model. For routine control, use appropriate reference masses across the actual working range, confirm zero and repeatability, and follow A&D's documented external calibration procedure when adjustment is required. Avoid calibrating simply because the last digit moves in a drafty or vibrating environment.
Who should consider EK-15KL?
Typical fits include formulation and batching, industrial sample preparation, research, production kitting, high-value material inventory, component counting, calibration-lab support and any application where a multi-kilogram load and 0.1 g display resolution are both useful. If loads routinely exceed 15 kg, compare EK-30KL instead of operating near overload.
EK-15KL FAQ
Does EK-15KL keep 0.1 g readability at full capacity?
Yes. A&D specifically markets EK-15KL for 15 kg capacity with 0.1 g readability across the full range.
Does this MNM listing include the battery?
The MNM SKU is EK-15KL-RB and the listing states the optional rechargeable battery is installed.
Is RS-232C optional?
No. A&D lists RS-232C as a standard interface on the EK-L series.
Can it count small parts?
Yes. Counting mode supports ACAI and a factory minimum unit-weight setting of 0.1 g, but actual count quality depends on part consistency and sampling.
Is 0.1 g the same as ±0.1 g accuracy?
No. 0.1 g is readability. Published repeatability, linearity, calibration and operating conditions must also be considered.
How large is the pan?
A&D specifies 300 × 210 mm, approximately 11.8 × 8.2 inches.
