Dialysis Reference Meters          

Reference Meters for the Service and Calibration of Hemodialysis Machines


Conductivity Conductivity      
Temperature Temperature    
Pressure Pressure    



Innovative Details


In using for hemodialysis, the meters can be used with any brand of dialysis machine.
Conductivity Measurement Years of experience with modern design and testing have proven that our 4-pole
electrode in carbon plastic technology provides superior performance.
This 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.

Also features facility for conductivity measurement of RO water.
The electrode is intrinsically tied to the meter and therefore cannot be misplaced.

Conductivity Temperature

Conductivity temperature coefficients are selectable by brand name,
ensuring high accuracy conductivity measurement.
Pressure Measurement
Provides readings in mmHg, kPa Bar or PSI.
A special mode allows measuring of the pressure drop.
The HDM97BQ and HDM97BO versions can be delivered with
a higher pressure measurement accuracy via an option, which allows
the calibration of blood pressure measurement devices in accordance with
DIN EN 1060 standard.
For the calibration of blood pressure measurement devices we offer a
calibration set according to EN1060.

For more details, please refer to
"How to calibrate blood pressure measuring devices"

Flow Measurement  
We provide an option for the
HDM97BQ that provides readings
in ml/min as well as showing the accumulated value.

More details on flow sensors.

Stop Watch  
The stop watch function allows accurate time measurement
to 100 m/sec. resolution.
Field Calibration HDM97Pocket meters can quickly and easily be adjusted and calibrated in the field,
thus minimising loss of time.
USB-Interface USB 2.0 - electrically insulated in accordance with ISO 60601-1.
Data exchange with other software is possible via the USB-Interface.
