  • Page 4: Introduction

    The HydroSCOUT meter is programmed with seven different programs which are easily selected using the program menu. Each program is setup to cover a specific analysis range and matrix combination. Built into each program are all of the conversions necessary to convert the measured pressure into water content.

    C with a Karl Fischer analysis on the same oil sample. The ratio of the HydroSCOUT result to the Karl Fischer result will determine the correct program to use for future measurements.

  • Page 6: Program G - For Water In Paint

    Program G -> Water in Paint (ASTM Method D 7358) Measurement Range: 2% – 85% Sample Matrix: Paints and Coatings Typical Application: Quality control of paints and coatings. This method is designed to measure the water content of liquid samples over the range of 1% to 100% (w/w) water content.

  • Page 7: Meter Operation

    Meter Operation The HydroSCOUT meter is fully factory calibrated and is ready to operate. Each time the meter is turned on, the micro- processor recalibrates the pressure transducer to zero and performs a QC check on the output voltage. While these checks are being preformed, relevant information on the meter will be displayed such as the software version loaded into memory and the current selected measurement program.

  • Page 8: Interferences

    Interferences In addition to the testing the effectiveness of the HydroSCOUT system in a number of matrices, extensive testing has also been conducted to document possible interferences and/or cross reactivities due to additives or components in a sample matrix. The following compounds have been found to produce no measurable response to the HydroSCOUT...

    Step by Step Instructions for Meter Operation Step 1. Press the <ON> Key. SCREEN: “-E34- ” is displayed followed by the currently selected program (i.e. “A 0-20%”) , then flashes “-bL-”, and then “tUbE.” ( “-E34-” is the current software version and “-bL-” indicates the instrument is undergoing internal calibration.) Step 2.

  • Page 10: Program B - Procedure For Testing Water Content Up To 100

    ANALYSIS: Press the <ON> key and make sure the meter is set for Program “A.” (NOTE: If changing the program, see “Selecting a Program” in the manual). Once the meter displays “tUbE”, insert the reaction tube into the opening at the bottom of the meter. The hole in the white cap must be lined up with the metal pin extending from the inside of the hole of the meter.

    CALCULATION: The meter is programmed to display the result in micrograms per milliliter (µg/mL). If a result is to be reported as a weight/weight value, divide the HydroSCOUT result by the density of the oil. Water in Oil (µg/g) = R/d where: R = Meter reading in µg/mL...
