4th Generation Technology with Clinician Calibration Capability
The Rossmax CH155F is a 4th-generation fully automatic upper-arm blood pressure monitor that adds a clinician calibration function to the full feature set of the CF155F series. The ability to recalibrate the device in a clinical environment is a significant advantage for healthcare facilities that perform periodic instrument verification against a reference standard ? a practice required in many regulated healthcare settings, including occupational health services, hospital outpatient departments and hypertension management programmes. The calibration function allows clinical staff to adjust the device’s calibration to maintain measurement accuracy over time, extending the useful service life of the instrument and supporting compliance with equipment maintenance protocols.
Real Fuzzy Technology, IHB Detection and Memory Functions
The CH155F uses Real Fuzzy Technology to compensate for patient movement during measurement, reducing the likelihood of inaccurate readings caused by arm motion. An Irregular Heartbeat (IHB) indicator alerts users to potentially abnormal cardiac rhythms detected during blood pressure measurement. Ninety memory slots retain previous readings, and the device calculates the average of the last three measurements automatically ? consistent with international hypertension guideline recommendations for reducing inter-measurement variability. A hypertension risk indication function provides immediate visual categorisation of each reading relative to international blood pressure classification thresholds.
Latex-Free Universal Cuff and South African Clinical Applications
The CH155F uses Rossmax’s latex-free universal cone cuff, fitting arm circumferences from 24 to 40cm without requiring cuff size selection, supporting efficient clinical workflow. The CH155F is CE certified and supplied to South African healthcare providers by Vital Medical. It is particularly well suited to occupational health services, GP practices and healthcare facilities that require an automatic blood pressure monitor with verified calibration maintenance capability ? ensuring measurement accuracy is maintained and documented throughout the instrument’s service life.
