Cleanroom Resistivity Tester
CLEANROOM RESISTIVITY TESTER | ||||
| Item Name: Surface Resistivity Tester Description: This durable and lightweight handheld meter measures both Surface Resistivity between two points (Rtt) and Resistance to Ground (Rtg). Test Range 105 to 1012 . Automatically generates a 10v or 100v test voltage for a 9 volt battery with results shown through a mutli-colored LED display. Can be used with the built-in parallel stainless steel electrodes or with optional external electrodes | |||
| Item Name: Probe Resistance Test Kit Description: This kit is designed to measure resistance between two points (RTT), surface to ground (RTG), and surface resistivity in accordance with ANSI/EOS/ESD S4.1 and S7.1. The display is an easy-to-read LCD and light emitting diodes (LED's) illuminates exponent numbers and functions. Kit comes complete with protective carrying case, two 5 lb. electrodes, set of test leads, Certificate of Calibration and 2 AA alkaline batteries. | |||

What is "CLEANROOM" ?
Typically used in manufacturing or scientific research, a cleanroom is an environment that has a controlled level of contamination. It contains a low level of environmental pollutants such as dust, airborne microbes, aerosol particles and chemical vapors. These contamination can be specified by the number of particles per cubic meter at a specified particle size.
What is "Electrostatic" ?
Static electricity is often generated through tribocharging, the separation of electric charges that occurs when two materials are brought into contact and then separated. Another cause is the electrostatic induction which occurs when an electrically charged object is placed near a conductive object isolated from ground. The presence of the charged object creates an electrostatic field that causes electrical charges on the surface of the other object to redistribute.
