Frequently asked questions
Does the TDS-100H need to be installed inside the pipe?
No. The listing describes clamp-on sensors installed on the outside of the pipe, and the sensors can be plugged and unplugged.
How do I connect the TDS-100H to a computer?
Use the isolated RS232 output. A PC without a serial port needs a suitable RS232-to-USB adapter, since RS232 signal levels differ from USB.
