Method
Method	Automatic oscillometric upper-arm measurement during deflation. Exact UK item 60493, EAN 4211125604936; manual model BM 23, technical type BM 25. Range tile and SEO title use BM 25, but active product heading, photos, datasheet and instructions identify BM 23. First-sale date unresolved	Automatic oscillometric upper-arm measurement; exact HEM-7121J-E. First retail sale period unresolved; manual publication and warranty dates are not substituted
Accuracy
Accuracy	Manual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse; systolic range 50–280 mmHg, diastolic 30–200 mmHg and pulse 40–199 beats/minute. Maximum cuff pressure 300 mmHg is separate	Maker pressure accuracy ±3 mmHg and pulse accuracy ±5% of displayed reading; blood-pressure range 20–280 mmHg, pulse 40–180 beats/minute and cuff pressure 0–299 mmHg
Clinical validation
Clinical validation	Current manual claims clinical testing to ISO 81060-2. Medaval lists a Stride BP derivative recommendation based on equivalence to BM 28 via Globalcare GCE603, but says unpublished equivalence results cannot be verified to MDR requirements. Independently established exact-device validation remains unresolved; headline flag omitted	STRIDE BP approves the exact model for adult home use by equivalence to HEM-7130, whose referenced study used ESH-IP 2010 and was published in 2015; this is not a separately published exact-model trial. Medaval separately says the equivalence results are unpublished and cannot be verified for its MDR assessment. Maker manual cites an 85-subject EN ISO 81060-2:2014 investigation and compliance with 2019+A1:2020, excluding pregnant and pre-eclamptic patients
Features
Features	Irregular-heartbeat warning, coloured classification scale, electronic cuff-position check, automatic switch-off and battery indicator. No ECG, dedicated AFib screening, resting indicator or voice output	Irregular-heartbeat and cuff-wrap indicators; no body-movement, high-blood-pressure or averaging feature in the exact maker table. No AFib screening or ECG recording; generic BPM & ECG category wording does not establish an ECG feature
Cuff

Cuff fits	22–42 cm	22–32 cm
Cuff
Cuff	Supplied universal cuff for 22–42 cm upper-arm circumference, replacement item 110.031; conventional hook-and-loop cuff rather than easyClip or easyLock	Included HEM-CR24 soft cuff fits 22–32 cm arms; approximately 145 × 466 mm with 610 mm air tube, 130 g. Optional compatible cuffs extend fit to 17–42 cm; this is not the included cuff range

Bluetooth and app
Bluetooth and app	No	No
Memory
Memory	No stored reading history, user profiles, date/time or calculated averages established by the product table or complete device operation section. Manual's isolated statement about resetting date/time and retaining saved measurements conflicts with those sections; not treated as an implemented feature	Stores the last measurement only
App
App	No Bluetooth connection from the monitor. Scan & Save captures the display with a smartphone camera into beurer HealthManager Pro rather than automatically transmitting measurements	No Bluetooth or OMRON connect transfer
Power
Power	Four 1.5 V LR03 AAA batteries included; manual approximately 300 measurements depending on blood pressure and inflation pressure. USB-C input supports optional 5 V DC / 1 A mains operation, not battery charging or a demonstrated data connection. Manual lists EU adapter 072.78 and UK adapter 072.79; remove batteries for mains operation	Four AA batteries or optional compatible AC adapter; DC 6 V, 4 W. Approximately 1,000 measurements with new alkaline batteries, under the maker's stated conditions

Display details
Display details	Non-illuminated LCD with black digits, maker 4.4 × 5.3 cm; physical START/STOP button. Manual IP21	Digital LCD; monitor IP20. Optional adapter has its own IP21 or IP22 rating, which does not apply to the monitor
Size
Size	120 × 90 × 40 mm (L × W × H). Manual and datasheet approximately 318 g with cuff and without batteries; current product table's 362 g excluding packaging has unspecified weighing conditions	Approximately 108 × 83 × 140 mm (W × H × L), 250 g without batteries, from the exact manual. UK and Dutch web tables instead list 112 × 140 × 82 mm; manual dimensions retained
In the box
In the box	Monitor, universal upper-arm cuff, four AAA batteries and instructions according to the datasheet and manual. Product page additionally lists a blood pressure record; mains adapter sold separately	Monitor, HEM-CR24 arm cuff, four AA batteries and instruction manuals 1/2. No storage case; optional mains adapter sold separately
