These robust single-gas detectors are made specifically to fit industrial safety requirements. Small in size and light in weight, these instruments provide easy, single-handed operation, even when wearing gloves. To ensure continuous operation, even when the unit is in a shirt pocket, the sensor has been carefully positioned to allow gas intake from both the top and the front of the device. Sensors offer a reaction time of just ten seconds and have a life of 2 years. In addition to a vibrating alarm, this unit emits an audible, multi-tone signal and a clear, 360º visual LED alarm. The large display shows both the gas concentration and the measurement unit. Monitors are able to store up to 60 events with dates and times, and can be linked to a PC.
