About
The NeoRTD External RTD Memory Gauge combines sapphire technology with RTD sensor to allow users obtain fast
temperature responses. This product is primarily designed for
detecting tubing and casing leakage problem. It could also be
used for other operations such as gradients and build up tests.
The same simple to use Neotek MaxView software is used for
programming gauges and conducting data processing. All files
are in ASCII data format.
