DESK AND WALL UNIT
MDF 840
The safety, durability, and convenience of the super-duty MDF® 840 aneroid sphygmomanometer, make it ideal for high-traffic areas in the emergency room, clinic, or ambulance. With a certified manometer, stress-tested over 3,000 times, and calibrated 5 times, it is one of the most durable, accurate, and dependable blood pressure measurement devices on the market.
MOBILE UNIT
MDF 830
The MDF® 830 Mobile Aneroid Sphygmomanometer incorporates all the features of the MDF® Desk and Wall Aneroid Sphygmomanometer on a quiet, sturdy, easy-to-roll stand. Perfectly suited for vicinities in hospitals, clinics, and nursing homes where repeated blood pressure measurements are conducted. Stress-tested over 3,000 times and calibrated 5 times, it is one of the most durable, accurate, and dependable blood pressure measurement devices on the market.

CALIBRATED 5 TIMES
Stress Tested 3000 Times
This certified 300mmHg manometer retains accuracy of +/- 3mmHg (Industry Standard). This is without the need of a pin stop which others use to keep the needle from going past zero and outside of these standardized limits. Each unit is stress tested over 3,000 times and calibrated at six pressure points (60, 120, 180, 240 and 300 mmHg) to ensure accuracy across your entire spectrum of patients.
FOR OFFICE PROFESSIONALS
Industrial Grade
To reduce the parallax effect, the large scale (15 cm) is imprinted with black-bold dials and pressed with a raised outer rim to achieve accurate viewing at all angles. Doubly protected against shock, the internal manometer is enclosed in a die-cast zinc housing that is cushioned within the external high-impact thermoplastic case. The faceplate can swivel smoothly with a wide range of 180° horizontally and 90° vertically to ensure the gauge is easy to see.


PRECISE DEFLATION CONTROL
Dependably Accurate
The screw-type valve rotates smoothly for a precise deflation control rate. The inflation bulb is constructed of crack-resistant, non-sticking, high-density, hypoallergenic, latex-free PVC.
LURE LOCK
Let's Go
Whether it’s switching out cuffs sizes from patient to patient, packing and unpacking your sphyg or simply replacing an old cuff for a new one, TIME MATTERS. The Lure Lock on the MDF® 840 is a quick release valve to save precious seconds between each and every patient.


INTAKE FILTER
The Details Matter
Even the smallest details make a difference. Like adding an intake filter to the base of the inflation bulb. This filter keeps out unwanted particles and debris that can interfere with air flow or the movement of the gauge.
UNIVERSAL CUFF
Plays Nice With Others
Perform accurate arterial compression with the artery indicator label and index range. The MDF® 840 comes with 3 sizes of cuffs (Adult, Large Adult & Pediatric). These double tube cuffs are compatible with all similar MDF® blood pressure systems. The High-Molecular polymer nylon cuff and case are abrasion, chemical (chlorine and peroxide), and moisture resistant.


REMOVABLE BLADDER
A More Hygienic Practice
High density, non-stick, non-racking inflation cuff bladder is easily removed to quickly clean for a more hygienic practice.
OPTIONAL VARIABLE CUFF SIZES
For Any Patient
Each MDF® 840 sphygmomanometer includes the standard Adult sized blood pressure cuff, along with a Large Adult and Pediatric sized cuff. We also offer these optional sizes to perfectly fit each and every patient. (thigh, large adult, newborn)
