Measurement range & accuracy

The AUTENS HT622A measures sound pressure from 30 to 130 dB with a stated accuracy of ±1.5 dB. Frequency response spans 30 Hz to 8 kHz, covering typical environmental and industrial noise. A colour LCD shows the reading together with a simulated sound-level bar.

Who benefits and who needs more

Suitable for technicians, facility managers and hobbyists who need quick spot checks in factories, workshops, offices or traffic areas. Not for users requiring Class 1 or Class 2 certification, data logging to a computer, or measurements below 30 dB.

Key decision spec

The single figure that decides fit is the 30–130 dB measurement range with ±1.5 dB accuracy; if your application demands a wider span or tighter tolerance, this meter will not meet the requirement.

Questions about this item

Does the HT622A need periodic recalibration to keep its ±1.5 dB accuracy?

The meter ships factory-calibrated; for critical work users typically send it to a calibration lab annually, but no user-replaceable sensor or calibration kit is included.

What limits continuous logging — battery life or internal memory?

The HT622A has no internal data-logging memory; readings are held on the LCD only, so the practical limit is the 9 V battery runtime during extended sessions.

How much heat or fan noise does the unit produce during all-day use?

The HT622A is a passive handheld meter with no fan or active cooling; it generates negligible heat and makes no audible noise while operating.
