Shipping Weight: 8-9 lbs approx.
Dimensions in inches: 6.25" wide, 13.75" tall, 1.6" deep
Calibration: Verify annually if necessary. Due to our moisture and shock resistant sensor, the need for calibration is unlikely.

     Each instrument is referenced (by comparison testing) to NIST traceable standard. All instruments are calibrated by type 1 precision sound level metering and sound calibration instruments.

Alarm Options: Instruments can be manufactured with one or two alarms. Each alarm is adjustable from 61 - 123 dB levels. Alarms can be considered as Hi/Low instrumentation style alarms. Each alarm activates an alarm indicator light and relay. Alarm indicator lights are bright red. Relay switching outputs are capable of 5-Amp., 250 VAC switching loads, and are isolated from any other circuitry.

Alarm 2: Has an additional "latching" option. This means, once activated, alarm 2  remains on. Alarm 2 must be reset in order to re-start it's latching option.

4-20mA Current Output Option: Provides an adjustable DC current to represent a sound level range. Sound level ranges can vary from 20 - 40 dB. Zero levels can be as low as 65dB. Current outputs are linear but, represent dB logarithmic ranges.

Remote Sensor Option: 1-500 feet distance for remote sound level sensor placement. This allows special monitoring and distance monitoring applications.

Re-ranging Instrument: For special sound level applications,  instruments can be re-ranged. (For example: 31-91dB instead of 61-121dB)
