Analygas® Systems Model 72 is a wall mounted gas monitor for use in non-hazardous indoor locations and housed in a rugged stainless steel enclosure that meets industry standard NEMA 4X. It offers a high degree of protection against dirt, corrosion and liquid ingress and is suitable for use in wash down locations.

The Model 72 has an electrochemical sensor that is  specific to the target gas and minimizes the chance of false alarms from interfering gases or vapours.

This instrument can be configured in sample drawing or diffusion formats. Filters, flow meter and pressure sensors are included to ensure correct flow conditions.

The front panel has an acrylic viewing window, behind which is a Vacuum Fluorescent digital display plus power and alarm status LED's. A keypad assembly allows selection and adjustment of many on-board features.

'Calibration has never been easier'

During routine calibration, the Model 72 detects the presence of calibration gas and enters its AUTO-CAL procedure, prompting easy to follow instructions on the display.
