Page 3: Read Before Operating
Read Before Operating This manual must be carefully read by all individuals who have or will have the responsibility of using, maintaining, or servicing this product. The product will perform as designed only if it is used, maintained, and serviced in accordance with the manufacturer’s instructions. The user should understand how to set the correct parameters and interpret the obtained results. -
Page 4: General Information
Do not use USB/PC communication in a hazardous location. General Information The NEO BENZ uses a combination of a selective 9.8 eV lamp and benzene filtering tubes to measure benzene selectively in mixtures of hydrocarbons as may be present in fuels or hazardous waste sites. -

Page 7: Charging A Lithium-Ion Battery
Charging a Lithium-Ion Battery Always fully charge the battery before using the instrument. The screen will display a battery icon from empty (no bars) to fully charged (3 bars). Follow this procedure to charge the instrument: 1. Plug the Micro-USB into the charging port at the bottom of the instrument. 2. -
Page 8: Instrument Basic Functions
Instrument Basic Functions The NEO gives real-time measurements or single-point benzene measurements and activates alarm signals whenever the reading exceeds preset limits. Prior to factory shipment, the instrument is preset with default alarm limits and the sensor is pre-calibrated with standard calibration gas. However, the instrument should be tested and the calibration verified before the first use. -

90' (27.5 m) vertically, at about 3' (0.9 m) per second flow rate. Note that at 200’ the PID response will be delayed by about 1 minute, the time required for the gas sample to reach the instrument. IMPORTANT! During operation, make sure the probe inlet and the gas outlet are free of obstructions. Obstructions can cause premature wear on the pump, false readings, or pump stalling. -
Page 10: Preset Alarm Limits & Calibration
Preset Alarm Limits & Calibration The instrument is factory calibrated with standard calibration gas, and is programmed with the following default alarm limits: Cal Gas Cal Span unit High STEL Benzene Isobutylene Alarm limits and calibration parameters can be adjusted in Configuration Mode as desired for particular testing purposes and applications. -
Page 11: Operating Mode Overview
Operating Mode Overview The instrument works in either VOC Mode for continuous VOC readings or Tube Mode for single-point benzene-specific measurements. The VOC Mode can be configured to read any desired gas using any correction factor (CF) or lamp, whereas the Tube Mode can only be used for benzene measurements with a 9.8 eV lamp. -

d. When prompted to insert a tube, open both ends of a benzene filtering tube using the tube tip breaker, taking caution to protect eyes and hands from sharp glass pieces. e. Unscrew the top section of the tube holder, insert the tube with the arrow pointing towards the instrument, and screw the top section back on. -

The reading displayed during the STEL measurement is not the instantaneous reading, but rather the accumulated STEL calculation. This is done so that the user can abort work or don protective equipment to avoid further exposure if STEL has been reached before 15 minutes have elapsed. Time Elapsed STEL = Average Concentration x 15 min. -
Page 15: Configuration Mode
Configuration Mode The Config Mode is used to modify the instrument configuration settings. Navigating Config Mode There are two types of menus in Config mode: 1) those that ask for selection from a list and 2) those that ask for a numerical value to be entered. Selection From a List For example, the Measurement sub-menu contains both a text-format list and a radial-button list. -

Note: The default password is 0000. The password can only be changed by connecting the instrument to a PC running mPower Suite software. Upon successfully entering Config Mode, the screen on the right will be displayed. The Calibration label is shown and its icon is highlighted. Use the Up key or Mode key to scroll through the menu until the... - Page 17 Fig 4: Flow chart for Configuration Mode...

Page 18: Calibration
Calibration Calibration Overview Because the NEO BENZ has two independent operating modes, both VOC and Benzene channels must be zero and span calibrated separately. Although the instrument will typically hold an approximate calibration for several weeks, when used for worker health and safety it should be calibrated or bump tested before each day’s use. - Page 19 Note: To abort the zeroing and proceed to Span calibration, press the Left key at any time during the process. A confirmation ‘Zero aborted!’ will appear, followed by the Span calibration menu. When complete, this message “Zero Calibration Done!” is shown, and the display automatically moves to the Span Calibration menu.

Press the Right key to select Gas Library, or Custom Gases. Press Up or Down to scroll through the gas list until the desired gas name is reached. For high-speed scrolling, press and hold the Up or Down key to skip by alphabetical first letter. Press Right to select the gas and Left to save and exit. Set Span Value Span value settings (including Span 2) should match the concentration(s) of standard gas. -
Page 21: Alarm Settings
Alarm Settings During each measurement period, the gas concentration is compared with the programmed alarm limits (Low, High, TWA and STEL). If the concentration exceeds any of the preset limits, the loud buzzer and red flashing LED are activated immediately to warn of the alarm condition. Press the Right key to enter the Alarm Setting menu. -
