Toxic and harmful gas monitoring

The hazards of toxic and harmful gases

hand-heldToxic and harmful gas monitoringInstrument features

• Low power consumption, long standby time

• Built in vibrator, suitable for extremely noisy environments in case of alarm

• When an alarm is triggered, 6 ultra high brightness LED light emitting diodes rotate and light up, while driving simultaneously

• The buzzer emits an intermittent 'beep beep' sound

• Two level alarm for high and low limits, with adjustable alarm points

• The special shell material has good anti slip effect
