Altair Pro

Altair Pro General Information

Innovative ALTAIR® Pro toxic gas and oxygen detectors are based on the design of the very popular ALTAIR® Single-Gas Detector, but with added features and functionality. These detectors accurately measure the gas concentration or percent oxygen (depending on model) and display this information on a large, clear, backlit LCD. The ALTAIR® Pro Single-Gas Detector features superior dust and water protection, excellent impact resistance, great RFI performance, and an extremely effective alarm system. Adjustable alarm set points are offered for LOW and HIGH levels on all units. In addition, the toxic gas versions also have TWA and STEL alarm points. A distinct alarm is indicated by two bright flashing LEDs, a piercing audible alarm, a flashing notification on the LCD, and an internal vibrating alarm, helping to ensure that no alarm condition will go by unnoticed. With current sensor options for CO, H2S or O2, the ALTAIR® Pro Single-Gas Detector will provide worry-free performance and stand up to the roughest handling in even the toughest industrial environments. The sensors and battery can easily be replaced to keep the unit performing perfectly for years. Its rubberized armor housing and one-button operation provide the durability and simplicity you expect. The ALTAIR® Pro Single-Gas Detector is designed and built with MSA’s superior quality and is part of the MSA STELLAR® Series, which features a varied selection of single-gas and multigas instruments.

Altair Pro Calibration guide

  1. Turn on the device by holding down the button on the monitor till the hour glass on the display disappears, other wise it will just shut off.
  2. Once the device is on hold the button for a few seconds till you see Test Gas?
  3. Once you see Test Gas? Hold the button once again for 2-3 seconds.
  4. This will bring up the Test Cal? screen. Press the button to confirm.
  5. FAS? will now appear on the screen. Press the button to confirm. This will zero the device and set the reading to fresh air.
  6. Once done Cal? will appear. Press button to confirm you are ready to calibrate.
  7. Apply the correct gas to the device using the tube.
  8. The device will beep and let you know if the calibration has passed or failed.
