Our take
Secura's SCG-903B manual describes a mains-powered household burr grinder with 17 settings, a hopper fill limit of 100 g and a 2–12 quantity dial that starts and stops a timed cycle. The dial is approximate: Secura warns that output varies with roast, bean type and grind size. Lid and grounds-bin switches prevent operation when parts are missing. The manual limits use to coffee beans and household quantities, with two full hoppers or two full 12-cup cycles followed by at least two minutes of cooling. Burr geometry/material and grounds-bin volume are not stated.
For household coffee-bean grinding where the buyer values a timed batch dial and confirms the offered SCG-903B label..
Not for commercial service, non-coffee grinding, exact weight dosing, uninterrupted operation beyond the manual's cycle limit, or a purchase based on the unresolved row finish or ASIN.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The maker manual documents a 17-position dial, approximate timed selector and a 100 g hopper limit.
- Safety switches and removable cleaning parts are described in the official instructions.
- Household-only use and cooling guidance clarify the intended workload.
What to weigh up
- Cup selection is a time control, not an exact yield or measured dose.
- The manual does not state burr geometry, burr material or grounds-bin capacity.
- The row's -BO finish and historical ASIN are not mapped to a current offer.

What the features mean for you
The maker establishes a household burr mill
Secura's official product page and linked manual identify model SCG-903B. The saved family includes source rows 78, 267 and 401, but the row-specific ASIN and the -BO finish clue are not mapped to a present offer. Apply maker facts only to an offered unit that actually carries the SCG-903B label. The maker sources describe a 17-setting grinder, while burr geometry and material are not specified. A matching product name is a starting point for checking identity, not proof that a historical listing remains available.
A quantity dial runs by time
The manual describes a 2–12 quantity dial and automatic stop at the selected time, with manual start/stop also available. Secura warns that the amount ground changes with coffee, roast and setting, so cup labels should not be read as guaranteed beverage yield or exact grounds mass. No integrated scale or gram target is documented. Someone who needs a weighed dose should use a separate scale or choose another model. The selector is best understood as a household convenience for approximate batches.
Hopper, safety and cleaning
Secura gives a maximum hopper fill of 100 g and describes switches at the hopper lid and grounds bin. The grinder will not run when required parts are absent. The manual explains removal of the adjustment ring for brushing and allows washing the hopper lid and grounds bin, while warning that the motor body must not be immersed or cleaned under running water. These steps help describe maintenance access, but the maker does not state the grounds-bin capacity or a removable upper-burr procedure.
Respect the run and use limits
The manual says the grinder is for household use and coffee beans only. It allows two full hoppers or two full 12-cup cycles before a break and calls for at least two minutes of cooling to room temperature between cycles. That wording does not give a throughput rating or approval for café work. Treat it as a practical stop point for home batches, not a service-volume estimate. The documented 120 V, 60 Hz and 110 W profile still needs comparison with the exact unit label before a hard electrical match.
A measured grind result is not documented
Secura's manual and product page provide brew and control guidance but no independent grind-distribution, espresso-extraction, retention, noise or durability measurements. A fine end of the selector does not by itself prove espresso suitability. For ordinary home use, the model may be worth comparing when the buyer wants a simple timed batch dial and confirms the rating plate. It is unsuitable for commercial service or a scale requirement. The attached model search does not verify the historical ASIN, finish, seller or current availability.
What else to compare
Before you buy
Does the SCG-903B weigh each dose?
No. Its quantity dial runs an approximate timed cycle; the manual does not document an integrated scale.
How much coffee can the hopper hold?
Secura gives a maximum fill of 100 g. It does not give a grounds-bin capacity in the saved manual.
How long may it grind before a break?
The manual permits two full hoppers or two full 12-cup cycles, then at least two minutes to cool.
Are burr shape and material identified?
The maker manual identifies a burr grinder but does not state burr geometry or material.
Is ASIN B07PQ75FXG a current -BO offer?
No current exact offer or finish crosswalk was verified; use the labeled SCG-903B search.
