WARNINGS 

 

STATIC HAZARD: Clean only with a damp cloth.

   

 

For safety reasons, this equipment must be operated and serviced by qualified personnel only. Read 
and understand the instruction manual completely before operating or servicing. 

   

 

• 

Use only mPower battery pack M011-3002-000. Substitution of components may impair 
intrinsic safety. Recharge batteries only in non-hazardous locations. 

• 

Do not mix old and new batteries or batteries from different manufacturers. 

• 

For maximum safety, the accuracy of the instrument should be checked by exposing it to a 
known concentration calibration gas before each day’s use. 

• 

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. It has two main detection modes: A continuous mode for VOCs (Volatile Organic 
Compounds) with a range from about 5 ppb up to 10,000 ppm, and a single-sample mode using a 
filtering tube for benzene specific measurements in the range 0.05 to 200 ppm. The continuous 
mode can be used to screen for benzene without a filtering tube, and if a response over the alarm 
limit is detected, a tube can be inserted to measure what fraction of the alarm response was actually 
due to benzene. The 45-second benzene-specific measurement time at room temperature is the 
fastest on the market.   

The NEO Series is one of the most advanced handheld VOC monitors available for ppb (parts per 
billion) detection, offering other models from the most sensitive 1 ppb to a high range up to 15,000 
ppm for different applications and user selections. Novel designs of the photo-ionization detector 
(PID) and ultraviolet (UV) lamp provide outstanding sensitivity, stability and reproducibility. 
Options include real time data monitoring with a built-in wireless modem using mPower Suite 
application software. 
 

Key Features 

• Size: 13.7 x 2.9 x 2.2 in (350 x 74 x 55 mm) with boot and tube holder 
• Weight: 28 oz (788 g) 
• 50 ppb to 200 range for benzene and 5 ppb to 10000 ppm for VOC 
• Fast 45-second benzene-specific response (at room temperature) 
• 3-second response time for 90% change (using isobutylene in VOC mode) 
• Large and intuitive display 
• Integrated correction factors list of several hundred compounds 
• Built-in pump for up to 30 meters sampling distance 
• Man-down alarm with real-time remote wireless notification 
• ISM wireless connection option 
• Easy service and maintenance 
• Micro-USB charge port
