The 740 Surface Resistance Meter is a pocket-sized instrument providing fast and repeatable measurements of conductive, static dissipative and insulative surfaces.

The 740 Surface Resistance Meter (SRM) provides fast and repeatable measurements of conductive, static dissipative and insulative surfaces.

The pocket-sized 740 SRM uses the ASTM Standard method of parallel bar sensing, features automatic ranging and is easy to operate (see Datasheet).

When measuring surface resistivity, an illuminated LED shows the decade in Ohms per Square. Resistance to ground measurements are shown in Ohms.

Traditionally used for checking packaging materials in the electronics sector, the 740 is now also used to check a wide range of materials and processes throughout industry.

Range 10³-10¹²+ Ohms per Square.

Resolution One order of magnitude.

Changeover Point ½ decade on logarithmic scale (3.15 x 10 n).

Accuracy of Changeover Point +/- ½ decade.

Accuracy +/- 10%. Repeatability: +/- 5%.

Test Operation Test battery - press button when holding in free air - the red insulative LED should illuminate.

Battery 9 V PP3 alkaline.

Dimensions 70 x 130 x 35 mm ( W x H x D).

Weight 103 g.

Equipment Meters are supplied with carrying case, battery and earth lead for resistance to ground measurement.

Environmental Temperature 5 - 50 °C. Humidity 0-90 % rH non-condensing.

Certification CE.
