Digital surface resistance tester with OLED display - A1-ESD DESCO 19291

The DESCO 19291 is a digital teraohmmeter for point-to-point and point-to-ground resistance measurements on ESD workstations, floor coverings and packaging materials. With switchable test voltages of 10 V and 100 V, it covers the relevant resistance range from conductive to insulating and delivers reproducible, standard-compliant results for ongoing ESD control.

Key benefits

• Large display: OLED display showing reading, temperature, relative humidity and test voltage at the same time.
• Complete documentation: internal memory for up to 100 readings.
• Fast range classification: additional LED indicator for the resistance exponent.
• Two test voltages: 10 V and 100 V for standard-compliant testing of different materials.
• Wide range: below 1.0 x 10³ to above 1.0 x 10¹² Ω.
