The Diamond Dial Deluxe Blood Pressure Apparatus (BPDL250) is a professional manual aneroid sphygmomanometer designed for blood pressure measurement by the auscultatory method using a stethoscope.
Manufactured by Diamond, the Dial Deluxe combines a large, clearly readable pressure dial with manual inflation, controlled deflation and a durable adult cuff. Its pressure scale covers 20–300 mmHg with 2 mmHg resolution, while the manufacturer specifies pressure accuracy of ±4 mmHg.
One of the most useful features of the Diamond Dial Deluxe is its field calibration facility. Diamond describes this as a self-calibration concept that allows the dial gauge to be adjusted in the field using the supplied calibration key if calibration error develops during use.
The casing is constructed from a high-profile Al-Zn alloy using pressure die casting, while exposed metal parts receive nickel and chromium plating for corrosion protection. The bellows and sector mechanism are engineered for durability and repeatability.
This makes the Diamond Dial Deluxe particularly suitable for doctors, nurses, medical students, clinics, hospitals, nursing homes and other healthcare environments where conventional manual blood pressure measurement is required.

Specifications are based on Diamond’s official BPDL250 Dial Deluxe product information.
The Diamond Dial Deluxe BP Apparatus is designed for manual measurement of blood pressure and can be useful for:
Because this is a manual auscultatory BP apparatus, appropriate training and a stethoscope are required for proper measurement.
The Diamond Dial Deluxe uses the traditional auscultatory method with a stethoscope, allowing trained healthcare users to identify Korotkoff sounds while manually controlling cuff pressure.
A major differentiating feature of the BPDL250 is its on-field calibration facility.
Diamond supplies a small adjustment key that allows the user to correct dial calibration error that may develop over time with use.
The printed dial provides a measurement scale from 20 to 300 mmHg.
The dial has 2 mmHg resolution, making pressure readings easy to follow during manual measurement.
Diamond states that the casing is manufactured from a high-profile Al-Zn alloy using pressure die casting, supporting durability for professional environments.
The internal sector mechanism is specially designed to support repeat accuracy, while the bellows use proven material intended for durability and repeatability.
Exposed metal components are treated with nickel and chromium plating to help protect against corrosion.
A specially designed cuff provides secure grip during measurement.
As a mechanical manual BP apparatus, the Dial Deluxe does not depend on batteries, charging or electronic displays.
A soft carrying case makes the apparatus easier to store and transport.
Diamond describes BPDL250 as a top-selling model with optimum damping and field calibration functionality.

The current Microsidd listing states that the sales package contains:
1 × Diamond Dial Deluxe Blood Pressure Apparatus
1 × Carrying Pouch / Case
The complete apparatus incorporates the dial gauge, cuff, bladder, tubing, inflation bulb and pressure-control components required for the BP apparatus.
Note: A stethoscope is required for auscultatory blood pressure measurement. Unless the physical pack you stock includes one, do not state that a stethoscope is included.
Unlike an automatic digital BP monitor, the Diamond Dial Deluxe requires manual operation.
The cuff is wrapped appropriately around the upper arm and inflated using the rubber bulb. A trained user listens to Korotkoff sounds with a stethoscope while gradually releasing cuff pressure through the hand-held control valve.
The dial indicates cuff pressure in mmHg, allowing the trained operator to determine systolic and diastolic blood pressure.
Diamond officially specifies auscultation with a stethoscope as the measurement method.

The Diamond Dial Deluxe BPDL250 is a manual aneroid sphygmomanometer used for blood pressure measurement through auscultation with a stethoscope.
No. It is a manual dial-type blood pressure apparatus.
The corresponding Diamond model is BPDL250 Dial Deluxe.
The pressure range is 20–300 mmHg.
The dial provides 2 mmHg resolution.
Diamond specifies pressure accuracy of ±4 mmHg.
Diamond specifies a cuff size of 14.5 cm × 51 cm.
No. The manual Diamond Dial Deluxe does not require batteries for operation.
Yes. Blood pressure measurement is performed by auscultation with a stethoscope.
Do not assume so. A stethoscope should be considered separately required unless your specific retail pack explicitly includes one.
No such feature is specified by Diamond for the BPDL250. I recommend removing this claim from the existing Microsidd listing.
No electronic hypertension indicator is specified for this manual dial apparatus.
Yes. A key feature of BPDL250 is its field calibration mechanism, which allows calibration adjustment using the supplied key.
It can be used wherever appropriate manual BP measurement is required, but correct auscultatory measurement requires proper training. For most untrained home users, an appropriate validated automatic upper-arm monitor is generally easier to operate.
Its manual measurement method, field calibration, durable construction and portable design make it particularly relevant for trained healthcare professionals.
No. This is a dial/aneroid BP apparatus. Diamond sells separate mercury and electronic-column models; the Dial Deluxe BPDL250 is the manual dial model.
Microsidd.com offers the Diamond Dial Deluxe Blood Pressure Apparatus as part of its healthcare and blood-pressure-monitoring range.
Customers looking for professional manual BP equipment can purchase the Diamond apparatus alongside other healthcare, diagnostic and clinical-use products from one specialised healthcare store.
