Depending on how many breaks/splices are in the wire, people have been able to trace wires across extremely large warehouses and stores. The more splices there are in the wire being traced, the weaker the signal is going to get down the line. Rule of thumb is for every spice in the wire, the signal is getting cut in half.
Depends on the wire, how deep it is buried, and the soil. Most wire that is going to be buried underground is going to have a thick jacket and possibly shielded. Shielded wire is going to block out the signal leaking out of the wire to be traced. Normally we answer this as no.
This depends on how far behind the sheetrock the wire is, the type of wire it is, if it is in conduit or not, how thick the sheetrock is, and how new the batteries are in the testers. As the batteries in the tester weaken, the signal being sent is weaker and the transmitter has a harder time picking up the signal. If the sheetrock (drywall) is extremely thick or even doubled up, that is going to affect the receiver’s ability to pick up the signal. If they are trying to trace BX wire (wire in an armored sheathing) or if it is in conduit, it will not be able to detect the wire. These metal encasements will block out the signal being sent and the transmitter will not pick anything up.
Currently we do not carry any of the replacement temperature probes. Best place to find replacement probes is from www.omega.com .
No, we currently only have non-contact voltage testers, not voltage meters. Any voltage reading would require having the test leads from the meter touching the circuit. Clamping the meter around a conductor with the meter on a voltage setting will not give any reading.
We offer the E1 lines splitter that isolates both the hot and the neutral conductors safely for the end user to take their measurement. Using this, you can either get a direct reading or a x10 reading for low current applications. This is only rated for up to 10 Amps. Any larger current draws would require making a custom jumper isolating each of the conductors. A professional electrician should be contacted for help doing this.
We do not have any type of covers or protective cases for the meters. Some units will come with a case, but we do not sell them individually.
