Be the first to review this product

The ACG+ is a unique compressed breathing air monitor
designed to be used in a fixed installation to your air

compressor or as an ideal portable solution for multi-
point air monitoring. The ACG+ offers the user peace

of mind as it continually monitors Oxygen (O2), Carbon
Dioxide (CO2), Carbon Monoxide (CO), dew point (H2O)
and Volatile Organic Compounds (VOC) and also has a
sample port to check for oil mist. It is simple to install,
use and maintain and has a low cost of ownership. The
ACG+ offers 90 days of datalogging, easily retrieved
with a USB connection and has audio/visual alarms and
a common relay to connect to a beacon or to shut down
the compressor should an alarm be triggered.

Portable or fixed

Mains, DC and up to 12 hour rechargable battery power options

Proprietary dew point sensor lock out system for fast start up - ideal for multi-point checking

Proprietary humidifier option for continual use to prolong electrochemical sensor lives (CO & O2)

Easy-connect purge system - helps ensure accurate readings in minutes

Robust carry case

90 days of datalogging easily retrieved via USB connection options

The ACG+ is built upon Analox’s latest innovations in sensor technology.
The new range of 5S3 and MEC intelligent sensors are Analox’s most compact,
miniaturised range of sensors to date. Each sensor comes with its own electronics
for signal processing and temperature compensation which enables each sensor
to become a field replaceable item.
