SURFACE RESISTIVITY TESTER 385

Hanstar model 385 -SURFACE RESISTIVITY TESTER

The first pocket resistivity Meter, with Specifications ranging from 10³ Ohms per square to 10¹² Ohms per square, with accuracy ± 1/2 Decade.

The meter measures both surface resistivity and resistance to ground. To measure surface resistivity, ¬simply place the meter on the surface of the material that requires measuring, and press the green test button. The meter will then light the appropriate LED from 10³ ~ 10¹²0hms per square or insulative. To measure resistance to ground, repeat this process and insert the earth leakage lead in the earth socket attaching the croc clip to your ground point.

The meter uses correctly spaced parallel bars for sensing its measurements and operates with a 9 volt battery giving over 40 hours of testing time.

SIZE: 130mm x 70mm x 25mm

HANSIN/ HANSTAR/ EXALT 498- Wrist Strap Tester

Hansin-Hanstar 498- Wrist Strap System Tester

Used to check wrist straps and ground cords, as well as the contact resistance between wrist strap and skin. To operate, simply connect the tester to the ground cord of the wrist strap assembly, and press the finger pad. If the wrist strap and ground cord are working properly (resistance between 500KΩ and 10MΩ), the green "GOOD" lamp will light up and an audible signal will be heard. A lit red "HIGH" lamp, with no audible signal heard, indicates loose contact between wrist band and skin (resistance greater than 10MΩ). A lit red "LOW" lamp, with no audible signal heard, indicates a faulty ground cord resistor (resistance less than 500KΩ). It Comes with 8-ft. grounding wire and 9V battery.

Features:
• Can be used anywhere for quick and easy checking variety of grounding systems.
• Ensures employee safety.
• Eliminates product defects caused by static electricity.
• Battery operated (included)

Specifications
Power Supply 9V Dry Battery

LED Indication Calibration Resistance Buzzer
LOW (Red) R <> 9M ohm OFF

Note: The tolerance in resistance is set to 0 +10% for the
Lower Limit of 800 KiloOhm and -10% to 0 for the upper limit of 9 MegaOhm
