The Protégé multi-gas monitor uses a Tri-Alarm warning system. The Protégé provides warning in hazardous conditions through dual bright red LED visual alarm, piercing 90dB (@15cm) audible alarm and vibrating alarm for noisy and harsh environments.
The glove tested Protégé has a simple two-button operation which makes calibration and basic operation simple. Its robust construction survives drops while being dust-tight and immersion-resistant.
The Protégé has a lithium ion battery pack which provides an 18 hour run time without a pump (diffusion mode) and a 12 hour run time with a pump.
