The HDM19 sensor modules are specially designed for the service of hemodialysis machines. The modules can be used with any brand of dialysis machine.


The HDM19 modules feature a USB and Bluetooth interface for convenient connection to Android devices such as HDC84. The internal rechargeable battery makes the module independent from the Android device battery.

Daily use

The HDM-Modules have been developed having the busy Biomed technician in mind. Helpful accessories such as the IV-Pole adapter and a pressure tubing set are included in the delivery.

Innovative Details

The Conductivity and temperature sensors are integrated into the flow-through path of the device.  Hansen dialyzer couplings can be connected directly.

Years of experience with modern design and testing have proven that our 4-pole electrode in carbon plastic technology provides superior performance. This technology provides reliable, stable and linear results for conductivity measurement. IBP is the only manufacturer of dialysis reference meters using 4-pole electrode construction for conductivity measurement.

The SmartHDM software allows to select Conductivity/Temperature compensation  coefficients by brand name, ensuring high accuracy conductivity measurement.
Pressure flow through  The UM modul version features an internal pressure
sensor integrated into the flow through path for the dialysate.
In combination with the external pressure sensor real
transmembrane pressure can be measured.

Readings are selectable in mmHg, kPa Bar or PSI.
A special mode allows pressure change measurement.
Pressure external
The pressure sensor has an external connector.
Readings are selectable in mmHg, kPa Bar or PSI.
A special mode allows pressure change measurement

Pressure ventilation valve    The UM modul version features pressure ventilation valve.
This functionality can be used in conjunction with Fresenius dialysis machines.
The valve can be activated by the SmartHDM-Software.
The valves opens the sensor flowthrough path to the environment.
The pressure outlet on the right side of the module.
USB-Interface   The communication interface is electrically insulated following ISO 60601-1.
With different interface cable, the module can be connected to USB with connector Type A or C.

Bluetooth Low Energy (BLE) / Bluetooth 4.2
Certified to FCC, IC, CE, KCC, NCC and SRRC

Registration Manufactured under certified quality management system
in accordance to ISO13485 standard.

FDA 510k registration as a medical device in USA.
