Watts TK-DL
Installation
The Watts TK-DL Computerized Backfl ow Tester is an advanced piece of test equipment designed to make pressure and differ-
ential gauges obsolete in the testing of backfl ow assemblies. Two solid-state, high-resolution pressure transducers provide the inter-
face to the computer. With 32K of memory, battery back up, 48 character super-twist display, 16 function keyboard and high-effi cien-
cy thermal printer, the TK-DL is equipped to provide real time data handling and the outputs required to test, validate and certify every
backfl ow assembly. (See operating manual for details). The TK-DL allows you to download your test results into a personal computer
for permanent storage. In addition, the TK-DL menu driven software program allows for customizing of printed header and footer.
