The Desco 19291 Digital Surface Resistance Meter is an instrument designed to measure resistance point-to-point (Rtt) or surface to ground (Rtg). Please note, the 19291 is only the meter. For the full kit, please see part 19290.
Its test functions include:
- Resistance measurement accuracy of ±10% (±20% accuracy for 1 x 1012 ohms and greater)
- Resistance range of <1 x 103 ohms to >1 x 1012 ohms
- Under load voltages of 10 and 100 volts ±5%
- Electrification period of approximately 15 seconds
The Digital Surface Resistance Meter also measures ambient temperature and relative humidity. Up to 100 measurements may be stored and recalled from the meter's internal memory. This includes the resistance value, temperature, relative humidity and test voltage at the time of the measurement.
The Surface Resistance Meter is referenced and designed to be used to make measurements in accordance with the test procedures in:
