Extech 480823 Electromagnetic Field Meter is a battery powered meter that measures and displays EMF in Gauss and Tesla units with a frequency bandwidth of 30 to 300Hz.
The Extech 480823 is a professional, battery-powered electromagnetic field meter that measures EMF in Gauss and Tesla units with a frequency bandwidth of 30 to 300Hz. The device features an LCD display capable of showing low battery and overload indications.
To operate the meter, switch it to the desired unit (Gauss or Tesla), move the sensor toward the device under test, and record the highest reading obtained from various angles. If a "1" appears on the left side of the LCD, it indicates an overload condition where the radiation exceeds the meter's capability.
| Measurement Rate | Approx. 0.4 seconds |
|---|---|
| Maximum Ranges and Resolution | 19.99µTesla (0.01) and 199.9mGauss (0.1) |
| Accuracy | ± (4% + 3 digits) |
| Frequency Bandwidth | 30 to 300Hz |
| Power Source | 9V Battery |
| Dimensions | 131 x 70 x 25mm (5.2 x 2.8 x 1") |
An overload condition exists, indicating that the measured radiation is higher than the capability of the meter.
The battery should be replaced as soon as possible when the low battery message "LO BAT" appears on the left corner of the LCD.
