• Digital compliance verification surface resistance meter kit
• Measures resistance point-to-point (Rtt) and resistance-to-ground (Rtg) of worksurfaces, flooring systems, garments, packaging, and other materials in accordance with several ESD Association documents
• Displays resistance mantissa and exponent, temperature, relative humidity and test voltage
• Internal memory stores and recalls up to 100 measurements - resistance, temperature, humidity and test voltage
• Measurement stability mode sets the 15-second electrification period for test requirements
• Electrode spacers space the 5 lb. electrodes to 10 and 36 inches for resistance point-to-point (Rtt) measurement requirements of ANSI/ESD S.1 and ANSI/ESD S4.1
• Resistance range of 1.0 x 103 to 1.0 x 1012 ohms

The Desco 19290 Digital Surface Resistance Meter Kit is an instrument designed to measure resistance point-to-point (Rtt) or surface to ground (Rtg).

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:
■ Compliance Verification - ESD TR53, Resistance Measurements
■ Worksurfaces - ANSI/ESD S4.1, Worksurfaces
■ Floors - ANSI/ESD S7.1, Resistive Characterization of Materials Floor Materials
■ Foot Grounders - ESD SP9.2, Foot Grounders, Resistive Characterization
■ Garments - ANSI/ESD STM2.1, Garments
■ Seating - ANSI/ESD STM12.1- Seating, Resistive Measurement
■ Floor/Footwear - ANSI/ESD STM97.1, Floor Materials and Footwear - Resistance Measurement in Combination with a Person
