INTRODUCTION

 

 
The Jerome

®

 431-X Mercury Vapor Analyzer is an ambient air analyzer with a range of 0.001 to 

.999 milligrams of mercury vapor per cubic meter (mg/m

3

 Hg). 

CAUTION: 

The Jerome

®

 431-X is for vapor use only. 

DO NOT

 allow the probe or the instrument's intake 

to be exposed to any liquid, dust 

or other foreign material. 

 
The 431-X is designed to be easy to operate for quick and accurate analysis of mercury vapor 
levels.  It has few maintenance requirements.  However, please take a moment to read this 
manual before attempting operation.  If you have any questions about your application or 
operation, please call AZI Customer Service at (800) 528-7411 or (602) 470-1414 or e-mail 

[email protected]

 for assistance. 

431-X Features 

 

•

 

Automatic sensor regeneration when equipped with the communications option and used 
with the Jerome

®

 Communication Software (JCS) program and the Jerome

®

 Data Logger. 

•

 

Regulated film heat voltage during sensor regeneration.  This allows the sensor to clean 
properly with voltages from 100-130 VAC (or 200-260 VAC). 

•

 

Survey mode can be locked in. 

•

 

DIP switch setting can change the digital meter readings from mg/m

3

 Hg to nanograms 

(ng) of Hg (see page 22). 

•

 

The Jerome

®

 431-X can be operated from 100-130 or 200-260 VAC.  To change the 

default voltage range, refer to Setting the Input Voltage, page 21.  

Accessories and Maintenance Parts 

The Accessories and optional items available to support the 431-X are listed and pictured
