Dialysis requires reliability and accuracy
The HDM99XP Meter allows the user to obtain reliable accuracy in measurement of conductivity, temperature, pressure, flow, pH and voltage. Frequency and period measurement are also possible. Developed by specialists with over 30 years of experience in the design of reference instruments for dialysis. The HDM99XP is an intelligent product featuring innovative technology, the end result is a product with an excellent price/performance ratio.
Advanced technology
Advanced processor technology combined tightly with highly developed software results in a completely new type of measuring instrument. Special features bring a level of accuracy not achievable with previous units. An easy-to-read graphic display and large keys make the HDM99XP convenient, not only to use, but handle. Operation is simple and completely menu driven. The language displayed is selectable from the options menu, choices available are Dutch, English, French, German, Italian, Portuguese and Spanish.
There are different ways of displaying measurements. These can be shown in graph format, including plotting. The graphs are adjusted automatically according to measuring range and the time interval can be user selected. The progress of all measurement parameters can be displayed at any time, this can greatly aid fault finding and diagnosis. There is an oscilloscope function built into the plotting display for voltage measurement. Conductivity measurement is carried out in 4 ranges up to 199.99 mS/cm, measuring ranges are automatically updated. The temperature reading is compensated in microsiemens or millisiemens, depending on which is selected.
Quality
The HDM99XP is produced under certified quality management system no. ISO13485 The device conforms to CE requirements. Each unit will have passed rigorous inspections before delivery. We also offer an annual calibration service and can provide a calibration certificate too upon request.
Trouble free calibration
Any operator can easily calibrate the unit via its intelligent menu-driven software. The software provides step by step menus aiding in the calibration process. To calibrate temperature, the temperature probe of the HDM is dipped into a liquid with a known temperature, this temperature can then be entered into the calibration program via the keyboard. To increase the accuracy, up to six calibration values can be entered. All measurement parameters are calibrated in this way.
