Peracetic Acid E-Cell® Sensor

ChemDAQ peracetic acid sensor with patented filter to give accurate real-time monitoring

Electrochemical Sensor Technology

Electrochemical sensors are a widely used sensor for work place gas monitoring.  Peracetic Acid diffuses into the sensor, through the back of the porous membrane to the working electrode where it is oxidized or reduced. This electrochemical reaction results in an electric current that passes through the external circuit. In addition to measuring, amplifying and performing other signal processing functions, the external circuit maintains the voltage across the sensor between the working and counter electrodes for a two electrode sensor or between the working and reference electrodes for a three electrode cell. At the counter electrode and equal an opposite reaction occurs, such that if the working electrode is an oxidation, then the counter electrode is a reduction.

The ChemDAQ Difference

Peracetic acid has become an essential antimicrobial and bleaching compound in many industries, and ChemDAQ was the first company to develop a sensor to detect PAA. Like our H202 sensors, ChemDAQ’s PAA sensors are always calibrated with PAA test gas. If you have a PAA or H2O2 monitor from another supplier, ask them how they calibrate their sensors. Do they use PAA or something else? PAA is always found with hydrogen peroxide and their chemical similarity means that there is some response from H202 on the bare PAA sensor. ChemDAQ's PAA sensor employs a unique filter that removes essentially all the H202 but lets the PAA pass through to the sensor. This innovative, patent pending technology is included with every ChemDAQ PAA sensor to provide our customers with the best performance in the industry.

Sensor Exchange Program is our solution to the issue of calibrating peracetic acid sensors

ChemDAQ Sensor Calibration Exchange (SXP)

ChemDAQ’s exclusive SXP service provides you with the assurance that your monitoring system sensors are calibrated and accurate.  This is done by delivering timely and consistent factory pre-calibrated sensors.

The SXP Program minimizes the time and materials needed to maintain your Peracetic Acid monitoring system. ChemDAQ centrally manages the maintenance schedules  providing  pre-calibrated sensors at prescribed intervals. 

Simple Three Step Process

1.  ChemDAQ notifies designated SXP contact person at your facility when it's time for new sensor(s)

2. ChemDAQ ships factory pre-calibrated sensors for each specific chemical along with calibration certificates. 

3. Designated SXP contact person connects new sensor(s) to monitor(s) and returns expired sensor(s) to ChemDAQ in the shipping container provided using the pre-addressed, pre-paid return shipping label.

Peracetic Acid Area Monitoring

Industrial Sampling System (ISS)

Our sampling system is housed in a water resistant stainless steel enclosure that continuously samples PAA in air. This enclosure is capable of withstanding high humidity, heavy fog/condensation and wash down conditions, while providing accurate readings of Peracetic Acid.

  • Fixed air sampling system for continuous monitoring of vapor concentrations at "hot spots" to help control exposure levels where people work

  • Employs ChemDAQ's E-Cell PAA sensor for accurate and dependable monitoring   

  • Designed for ease of use, especially when exchanging PAA sensors

  • Vapor draw system pulls air sample into the sensor and keeps it contained reducing the risk of condensation damaging the internal components

  • The system is designed to connect to the DAQ system (see below) or a customer's PLC via WiFi, RS-485 or 4-20 mA current loop interface

  • Front panel indicators for power and air flow fault detection

Industrial Area Monitor (IAM)

This product only works in conjunction with the Industrial Sampling System. Our Industrial Area Monitor for Peracetic Acid is a water resistant stainless steel enclosure with a clear window that allows visibility of the LCD touchscreen mounted internally.

  • Water resistant, stainless steel enclosure

  • Continuous real-time monitoring and display of vapor concentrations in parts per million (PPM), as well as, calculations of 8 hour and 15 minute time weighted average (TWA) exposures

  • User adjustable "impending" alerts provide advanced warning before PAA  exposure reaches unsafe limits

  • Control settings for ventilation/air handler and PAA scrubber system

  • Exposure data is collected and stored in .csv format and is downloadable for analysis and reporting purposes

Steri-Trac 2+ Area Monitor

ChemDAQ's continuous monitor ensures your employees are safe in real-time. The ST2+ fixed monitor pairs with our PAA E-Cell sensor to continuously monitor and alert you to hazardous vapor levels in the air. This provides a fully integrated, intuitive system with flexible options for monitoring Peracetic Acid exposure.

  • Real-time measurement of vapor concentration in parts per million, while simultaneously calculating an 8 hour and 15 minute time weighted average (TWA)

  • Easy to use "plug & play" setup

  • Mount by acrylic stand or wall mount

  • Visual and audible alerts are factory set to meet regulatory requirements, but are customizable to user preference

  • "Impending" alerts warn as exposure is approaching unsafe limits allowing for proactive measures to prevent exposure to hazardous chemical vapors

  • Data collected and stored in .csv format and is downloadable for analysis and reporting purposes

Our Data Acquisition System shows peracetic acid levels throughout monitored area

Data Acquisition System (DAQ)

The CHEMDAQ Data Acquisition System (DAQ) is a PC-based computer software system that continuously Gathers, Analyzes, Reports, Displays and Stores (GARDS) workers against high concentration Peracetic Acid (PAA) exposures for up to 32 Area Monitors simultaneously. This integrated system helps to monitor immediate and long term exposure of Peracetic Acid.

As an area monitoring and archival system, the CHEMDAQ Data Acquisition System is not intended to meet the OSHA 29CFR1910·1047(d) requirement for initial and follow-up personnel monitoring. The Area Monitor units of the Data Acquisition System fulfill the requirements of OSHA 29CFR1947(h)(2) for alerting employees in emergency situations.

The Data Acquisition System (DAQ) increases the effectiveness of individual Area Monitors by:

  • Centralizing all monitoring data;

  • Comparing all exposure levels to OSHA standards and requirements for user safety;

  • Alarming when these levels are exceeded or may be exceeded if current concentrations continue (Impending Alerts);

  • Documenting and storing all Area Monitor activity for current review and/or later retrieval; and

  • Storing exposure, maintenance and calibration histories of each Area Monitor unit.

Remote Video Display (RVD)

The Remote Video Display duplicates the display from the DAQ computer to a video monitor, that workers and supervisors can view all sensors from a single location. Do you have a door leading into your monitored area? Putting a Remote Video Display outside of it will let everyone know it is safe to enter before entering.

Remote Display Repeater (RDR)

Do you want to see a rooms exposure levels from a safe distance? Our remote display is perfect for you to keep yourself clear from over-exposure to any of our chemicals. The remote display duplicates information received from the fixed monitor, which can connect to one or more remote displays. Remote displays are typically wall mounted outside of monitored areas to warn personnel of gas levels prior to entry.
