The Trek Model 152-1 Surface/Volume Resistance Meter is designed to precisely measure surface or volume resistance on a wide variety of conductive, dissipative, and insulative materials. The Model 152-1 employs a measurement technique which conforms to ANSI/ESD Association standards for measuring surface resistance, resistivity, and volume resistance including STM2.1 for garments, S4.1 for work surfaces, S7.1 for flooring, STM9.1 for footwear, STM11.11 for planar materials, STM11.12 for volume resistance (IEC 61340-2-3), STM12.1 for seating, STM11.13 for two point resistance measurement and STM97.1 for floor materials/footwear. A variety of measuring probe electrode configurations are available and are purchased separately.
The Model 152-1 features exceptional measurement accuracy and wide measurement ranges of 103 to 1013Ω using point-to-point probes or the two-point resistance probe for small surface area measurements. When used with the exclusive 152P-CR-1 concentric ring probe that contains a pre-amplifier, the usual noise, stray pickup and long settling time associated with other concentric ring probe designs is eliminated, thus providing ease of operation even at very high resistance values.
The electrode test voltage for the measurement probe(s) is switch selectable for 10 V or 100 V operation to conform to the individual requirements of the ANSI/ESD Association standards and testing conditions. The selected test voltage is indicated on the LCD display. The light-weight portable unit is operable via batteries or an AC line power source with a battery eliminator.
The Walking Test Adapter Kit [CN 1K039 ] for the Model 152-1 Surface/Volume Resistance Meter allows analysis of resistance levels on the human body.
The resistance of a person to ground in an electronic environment can be measured with the Trek Walking Test Adapter. This test provides measurement data of actual resistance on a person in multiple locations. This test ensures ESD safe practices, such as STM 97.1 "Body System to Ground" resistance measurements, are being implemented properly and that proper resistance is being maintained.
