This product is now obsolete.

ALTAIR PRO features a broad range of field proven, fastresponding 20 series sensors. Choose from O2, CO, H2S, NH3, Cl2, ClO2, HCN, NO2, PH3 and SO2 configurations. All sensors are simple to fit reducing instrument down time.

Some outstanding features include:

  1-button operation
  Bump check confirmation [lasts 24 hours]
  Configurable alarm setpoints
  High performance audible, visual and vibrating alarm
  Full data-logging as standard
  IP67 rated
  Fast-responding 20 series sensors
  Easy to read gas concentration display
  Replaceable sensor and CR2 battery
  Multiple clip options

The replacement of both the sensors and batteries is incredibly simple, minimising any maintenance downtime. The highly efficient, commercially available battery ensures the ALTAIR PRO will run for over a year when used over a standard working week.

ALTAIR PRO features an extra thick rubberised housing which provides resistance to water and dust ingress. With the rugged suspension clip fitted as standard the ALTAIR PRO can be securely attached to clothing. A highly comprehensive datalogging facility is standard on ALTAIR PRO. Via the built-in Infra-Red link data is transferred to a PC where information can be assessed quickly and easily.
