Designed originally for flat (planar) packaging materials, this unique portable test fixture will measure Surface and Volume Resistance of virtually any flat material in accordance with current industry standards.These include Surface Resistance per ANSI/ESD STM11.11, and Volume Resistance per ANSI/ESD STM11.12, and will approximate surface and volume resistivity measurements per ASTM D-257.Note that ANSI/ESD Standards are for materials employed for electrostatic discharge control, while ASTM D-257 is used to assess insulating materials utilized in electrical distribution and power applications.
The PRF-911 Concentric Ring is a low-profile test fixture conceived specifically for use with the Prostat Resistance instruments such as the PRS-801 Resistance System, PRS-812 Resistance Meter and the PAS-853B Resistance Auditing System.The Concentric Ring is an important tool to caluculate surface resistivity and volume resistivity. For example, multiply the surface resistance measurement in ohms by 10 to obtain surface resistivity in ohms/square.
Its compact size allows the fixture to be inserted into small flexible containers, such as an ESD protective bag, without having to cut the package.
The PRF-911 incorporates a spring loaded, self-aligning center electrode feature. This unusual feature aids in maintaining consistent contact of the fixture’s highly conductive rubber electrode surfaces with materials under test.This reduces the need for frequent calibration and alignment of the fixture.
The PTB-920 Dual Test Bed consists of an insulated test surface for S11.11 surface measurements laminated to a steel test plate, which is employed for volume resistivity measurements.The four inch diameter steel test bed assembly includes a banana receptacle for instrument connections during volume measurements.
The PRF-911 is capable of accurate measurements from less than 100 ohms (<1.0x102ohms), to greater than 1.0x1012 Ohms (>1.0x1013 ohms/square). The fixture is configured so that it can be connected to either an instrument ground reference or earth ground to minimize the effects of extraneous fields and charges on the measurement.

SHIPPING
A delivery and handling charge applies to all orders with the exception of back-ordered items.
Unless otherwise required by Buyer, Seller will make transport arrangements as follows:
For deliveries within the metropolitan areas of mainland State capital cities a standard freight charge may be added to invoice; goods
For delivery outside those areas, seller will select the transport to be used and prepay freight for Buyer. Seller will then bill Buyer for freight at Seller's discretion.
Should the Buyer request goods be sent to a Post Office box the Buyer acknowledges this method is the only available and therefore the Seller is not liable for undelivered goods.
Free shipping on orders over $199 incl GST (valid for 1 delivery per order and excludes NT, WA & TAS). If only part of the order is in stock, the customer has the option of paying for a second delivery if they require a partial shipment prior to all goods becoming available. Mektronics Australia reserves the right to charge additional freight in the event of hazardous, bulky or heavy items ordered.
DELIVERY TIME
All quoted delivery or consignment dates are estimates only, given without engagement.
Delay in consignment of any part of an order shall not relieve Buyer of its obligation to accept and pay for the remainder of the order.
Except as provided in paragraph 1.2 of Terms & Conditions, seller will not be liable to pay damages or compensation for any injury or loss sustained by Buyer
a) in the event of a delay in consignment or delivery of goods: or
b) in the event of non delivery.
Goods offered ex-stock by Seller are subject to prior sale.
In the event of any happening beyond Seller's reasonable control in consequence of which Seller cannot effect consignment by the time or times quoted or specified, Seller shall be entitled to consign part only of an order, suspend consignment or extend the time for consignment, for the period during which such cause of delay operates, or may cancel the order, and in the event of such suspension, extension or cancellation, Seller shall not be liable for damages.
