The Gas Alarm Clip provides two years of continuous maintenance-free operation from the day of activation.
The Gas Alarm Clip provides two years of continuous maintenance-free operation from the day of activation. Operated by an advanced microcontroller and electrochemical sensor, the unit is equipped with two levels of alarm, a full feature LCD status panel and high output audible/visual alarms.

Simply press the START/TEST button and the unit is ready for use. The life remaining is displayed in months, then days and then hours. The full function self-test verifies sensor, circuit and battery integrity and audible/visual alarms.

Alarm setpoints, peak alarm and the time elapsed since the peak alarm occurred are displayed on command. Generate a permanent record of gas alarm events encountered. Transmit stored event data to a cordless printer.

The rugged, compact unit is designed with the most advanced RFI protection available in industry today. Simply clip the instrument to your lapel, pocket, belt or hard hat for unequaled cost effective protection.
 
Features
  • Two years of protection with zero maintenance costs
  • Continuous, alphanumeric LCD shows detector life remaining, alarm setpoints and advises self-test status
  • Records and displays the peak alarm encountered and the time since the exposure occurred
  • Records and transmits gas alarm events encountered and the time elapsed since the event occurred
  • Two alarm levels (Low / High)
  • Provides ≈85 dB tone and bright LED indication on alarm
  • Internal vibrator alarm
  • Small size (1.1 x 2.0 x 3.2 inches / 28 x 50 x 81 mm) and lightweight (2.6 oz. / 73 g)
  • Maintenance free – no sensor or battery replacement, no calibration, no downtime
  • Full function self-test of: audible/visual alarms plus integrity of sensor, battery and circuitry
  • Continuously ON – one button activation, test and data transmission
  • Comes complete with pocket/belt clip, test cap and hose
  • Optional alligator and hard hat clips available
