Badge-Type Ambient Ozone Monitor

a.  Shall measure the level of ozone present 

in the room where ozone equipment is 
located.

b.  The ChromAir

®

 System ozone badge (K&M 

Environmental P/N 380010-10; www.
kandmenvironmental.com; 1-800-808-
2234) may be used for personnel or area 

monitoring for exposure times ranging from 
5 minutes to 10 hours. For higher resolution, 
the ChromAir ozone badge may be used in 
conjunction with the ChromAir ozone color 
comparator.

b-1. ChromAir System features:

•  Constantly monitors work environment

Other ambient ozone monitors are also avail-
able. Contact DEL for further information.

OZONE IN WATER
The ozone concentration in water can be measured 
in different ways.

1.  Oxidation Reduction Potential (ORP) monitor 

measures the effective biocidal activity of 
dissolved ozone in water in millivolts and can 
be converted to mg/l (PPM). NOTE:  ORP 
is an 

ineffective measurement of ozone 

concentrations greater than about 0.5 PPM.

2.  Dissolved Ozone monitors measure levels 

of dissolved ozone in water (mg/l or PPM). 
The HACH Indigo Blue AccuVac high range 
dissolved ozone test kit (DEL P/N 6-0116) is an 
inexpensive colorimetric test. Electronic, in-line 
dissolved ozone monitors are also available. 
Contact DEL for further information.

6E-3. Ozone Detection Data Log
In addition to automatic chart recorders, operators 
should log ozone monitor output. Record ozone 
output data twice per shift (maximum 12 hour shift). 
If system does not have an automatic chart recorder, 
record data every 4 hours, regardless of shift 
changes. 

(See Daily Data Log - page 10).
