90XL Dialysate Meter
The 90XL is a state-of-the-art, portable, multifunction meter designed to measure the conductivity, pH, temperature and pressure of the dialysate fluids from hemodialysis delivery systems and of the water used in hemodialysis clinics.
The 90XL Meter is a modular system. The system consists of the display module and the sensor modules. The display module is the controller for the system with a large display, microprocessor, circuitry, keypad and a rechargeable lithium ion battery power supply. Individual sensor modules are available for measuring either conductivity/temperature, pH, or pressure. The sensor modules contain the appropriate sensors and the circuitry for measuring the desired parameter of the sample solution. Up to four sensors, in any combination, can be used simultaneously, with all parameters displayed on the display module screen.
Provides Confidence
The 90XL provides highly accurate and precise measurements of conductivity in both the high and low ranges and has the long-term stability required for the most demanding applications. It can be used to test and calibrate all types of delivery systems and water purification systems.
Convenience
Up to four different sensor modules in any combination can be used at one time with the 90XL for the ultimate in flexibility. The 90XL has an easy to use field calibration program that guides you step by step through the entire calibration process. When service is required, only the sensor module needs to be returned to our service department for an annual calibration or certification. There is no need to return the entire meter. This saves you down time as well as shipping charges.
Easy to Use
The easy to read screen on the 90XL's display module can show readings of all installed sensor modules simultaneously for true hands-free operation. The easy to understand on-screen prompts guide you through the measuring process. When calibration is required, our calibration wizards guide you through the entire process for added confidence. And, when you have questions on meter operation or calibration, an on-line help feature is built into the meter, accessible through a single keystroke. The 90XL meter sets the standard in the industry for ease of use.
