Alpha Lab, Inc.
The AlphaLab Voltage Touch Monitor enables personnel to identify voltage problems that usually remain hidden. The monitor reads the voltage on a finger (which is identical to the voltage at every other point on the body). It can detect as little as 1/10 volt in two modes: DC and AC/Spikes (ESD transients). In the DC mode, the displayed voltage is either positive or negative, and is usually very low if grounding is being worn and is functioning properly. Higher DC voltages (even while grounded) occur if a DC ionizer is blowing too close or if the person rubs against a high-static material or comes in contact with metal at a DC potential. If personal grounding is not being used, any DC signal can build up over time, and the DC mode continues to show the instantaneous body voltage as it changes. In the AC/Spikes mode, any transient voltage spike at least 1/2 millisecond long is temporarily displayed. If there are several consecutive spikes, only the highest is displayed, regardless of polarity. If the signal is a repetitive (AC) wave, the peak voltage is displayed, but always as a positive number. Even when proper grounding is worn, several tens of volts often occur with transients and AC. Maximum error for DC and AC is only 2% of the reading +/- 0.1 volt.

Oersted Meter -
Alpha Lab, Inc.
The Air Shipment Milligauss Meter has been designed so that one person alone can be the tester, and do repackaging, if necessary, without moving from the area. The remote sensor, shown on the right side, is connected through a 15-foot cable to the control box (left). This control box is placed next to both the package and the tester (person) so the tester can manually rotate the shipment. The remote sensor is placed either 15 feet or 7 feet away, depending on which test is being done.
