Digital Surface Resistance Meter Kit - 

19290 is a digital surface resistance meter kit. It is an instrument designed to measure resistance point-to-point (Rtt) or surface to ground (Rtg). Its test functions include resistance range of <1 x 10^3ohms to >1 x 10^12ohms, under load voltages of 10 and 100volts ±5% and electrification period of approximately 15seconds. 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.
