The model 890e is the latest member of the 890 family of versatile fuel cell test loads. These computer-controlled instruments consist of a multi-range programmable electronic load, fuel flow and temperature controls, and data acquisition functions in a compact rack-mount or bench-top unit. Add the 880 Frequency Response Analyzer (FRA) option for integrated High Frequency Resistance (HFR) and full range Electrochemical Impedance Spectroscopy (EIS) measurement.  *NEW* The 890 Series is now supported by the SAI 885 Integrated Fuel Cell Potentiostat!


Featuring Multiple Current Ranges in 5/25/50A, 10/50/100A, 12/62/125A or 25/125/250A Configurations at 125W or 500W and 50/250/500A at 1KW

The 890e is the latest member of the 890 family of versatile fuel cell test loads. The 890e is a computer controlled instrument with a multi-range programmable electronic load, fuel flow and temperature controls, and data acquisition functions in a compact rack mount or bench top unit. The 890e series loads are targeted at small to medium size (up to 500A, 1KW) single cell or low-power stack for laboratory research. The 890e's multiple current range capability enhances its versatility and performance over a wide range of test applications and test environments.

New Model Available: 890e 50/250/500A 1,000W

The 890e sets the new benchmark, in value and performance, for fuel cell test loads. The 890e is fully compatible with our FuelCell® (Windows 2000/XP) software package creating a powerful tool for conducting your experiments.

Improved Performance and Enhanced Features at the SAME PRICE!


The 890e is designed for use with a fuel cell or stack, custom or third-party fuel management unit, and our optional internal model 880 Frequency Response Analyzer (FRA) for full-spectrum Electrochemical Impedance Spectroscopy (EIS) and continuous High Frequency Resistance (HFR) measurement.
