Product Description
AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter UL 913 Intrinsically Safe Bonding Milli-Ohmmeter USAF NSN 6625-01-542-7487 Bonding Milli-Ohmmeter*
AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter Compliant to UL 913 as an intrinsically safe apparatus for use in Class 1 Division 1, Groups A,B,C, and D, Ambient temperature -20 °C to 50 °C. Approved for UL913 Flight-Line Safety Standards
![]() AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter is now UL 913 certified as an “Intrinsically Safe Apparatus” for use in Hazardous (Classified) locations and safe for use around Aircraft (Fuel-Air Areas), Fuel Cells/Tanks, Gas Systems, and around Aircraft Fuel Installations. It will not make a spark. |
AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter Certified UL913 Approved for UL913 Flight-line Safety Requirements
The brand new, UL 913 Intrinsically Safe AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter is a portable Low Resistance Explosive Safety Bonding Micro- Ohmmeter ideal for bond determination offering 0.001 milliohm resolution . The meter is based upon the AMPTEC 620UK and 620UK-B Bonding Ohmmeter design and safely measures bond resistance from 0.001 milliohms on the 19.999 milliohm range in Volatile and Explosive Atmospheres.
After a thorough evaluation by the USAF Electrical Standards Bonding and Grounding Group, the AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter has been placed at the top of their list as approved for use on Boeing 707, Boeing 727, Boeing 737-747, Boeing 757-777 for Ground bond testing in explosive hazardous areas. Just ask some of growing list of commercial airline customers (contact AMPTEC Sales Dept.) about how they prefer the new AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter or reliability, accuracy and ease of use over the antiquated pricey competition (almost $10,000.00) like the AVTRON T477W bond meter or the bulky BCD M1 Bonding Milliohmmeter. With UL913 certification, AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter is certified to be an INTRINSICALLY SAFE APPARATUS AND ASSOCIATED APPARATUS FOR USE IN CLASS I, II, AND III, DIVISION 1, HAZARDOUS (CLASSIFIED) LOCATIONS.
AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter approved by US Air Force
Since the AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter is Approved by the USAF and it is also Mil Std 810 Method 511 Explosive and Volatile Fuel Air use in hazardous environment compliant, it is ideal for safe use around volatile fuel air hazardous areas, such as aircraft refueling and is certified safe by the UL913 certification. The AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter (Milli-Ohmmeter) is approved for use in hazardous and volatile environments for use around Aircraft (Fuel-Air Areas), Fuel Cells/Tanks, Gas Systems, and around Aircraft Fuel Installations (Will Not make a Spark).
AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter ~ Low level Bond Milli-Ohm Measurements made Easy
The intelligent AMPTEC 620LK-HR Aircraft Safety Bonding Ohmmeter “Auto-locks”, once continuity is established, onto the lowest resistance (bond) measurement automatically. The “Auto-Lock” feature (signaled with a yellow backlit display) “Locks-On” & holds (displays) the lowest ohm bond measurement by the operator lifting the Kelvin probes (continuity broken). The low level bi-polar bond resistant measurement (average of both polarities of the meter’s current source) eliminates errors from thermal emfs and any potential offset error(s). No range changes to deal with, No zeroing of the test leads. No erroneous readings, only when continuity is made, does it continuously sample measurements and lock in the lowest resistance reading and “Auto-locks” on the bond reading by holding it “frozen” (simply re-establish continuity with the Kelvin probes or press the reset button to start over.
