Does the water extraction have to be done for the zero?

 If you have access to ethanol free gasoline for the sample being tested, you can use that for your zero.  If not, we recommend doing the water extraction.  It takes less than a minute and the zero (ethanol free) gas is easily removed from the top.

Can an InfraCal Ethanol Blend Analyzer be used for analyzing biodiesel in diesel?

No.  The InfraCal Ethanol Blend Analyzer can not be used for analyzing  biodiesel (FAME) in diesel.  The filters in the analyzer are preset for ethanol in petrol/gasoline analysis.  The InfraSpec VFA-IR Spectrometer, Model ES can be used for measuring both ethanol in gasoline and biodiesel in diesel.

When I press run nothing happens.

If you press and hold the run button rather than press and release, it will go into the timer-setting mode.  To reset the timer to the appropriate evaporation time, use the up and down arrows on the buttons.  Once the timer is set, press the "CAL" button and the display will return to "idle".  Please refer to section 3.4.2 in the Users Guide for a detailed description.

Can I use the External 12 v Battery Pack outside of North America?

The battery pack is supplied with a US AC adapter that requires a 115v 60 Hz input to recharge the battery.  Customers using the battery pack outside the US would need to supply their own converter with the appropriate outlet to convert their country's power to the 115v 60 Hz.

Does Wilks sell used equipment?

No, we do not sell used equipment.  Our analyzers are generally in use for more than 7 years and it would be more costly to refurbish an old analyzer than to build a new one.
