Watts No. TK-99D

New Backflow Preventer Test Kit

The Watts Model TK-99D hand-held digital test kit is an advanced test instrument designed to test PVB's, SVB's, DCVA's, DCDA's, RP's and RPDA's. The high contrast LCD display and large 5/8" height Differential Character make backflow testing a snap.

This compact test kit features .25% Full Scale "Accuracy" in addition to a low battery indicator and an automatic shutdown feature to conserve battery life. Why lug around gauges weighing 15 lbs or more? At "less than 3 lbs", the TK-99D test kit from Watts Regulator beats the competition hands down.

Watts TK-DL


Say Hello to 'TK-DL' ...That's short for Test Kit with Digital Print-Out - the finest piece of field test equipment made today.

Imagine for a moment that you could test backflow prevention assemblies in the field with the same digital print-out confidence that our quality control technicians achieve at the factory.

Well, that's exactly what the Watts new TK-DL is all about. Through the power of microprocessors, Watts shrank their factory test bench into a small also lightweight traveling companion that replaces both pressure and differential test gauges. Regardless of the job - pressure vacuum breakers, reduced pressure backflow preventers, or double check valve assemblies - the TK-DL is the only test gear you'll need.

But versatility isn't TK-DL's only claim to fame. It's also substantially more accurate than mechanical test gauges (to ± 0.2%) and features an easy-to-read numerical display that eliminates the reading errors common to analog dials and pointers. High-side, low side, and differential pressure are continuosly displayed and recorded in the unit's 32-K memory.

Best of all, the TK-DL gives you printed, on-site documentation, recording the time, date, and verified test results. If you like, you can print a copy for a client, to be left at the site, then print a second copy for yourself, to be filed in you office. Either way, you get real-time verification that the backflow preventer was puncutally and properly tested. If the test should ever be challenged - as is sometimes done in litigation - you have the printed test results as material proof. And since the TK-DL holds 50 three-minute tests in its memory (or 75 shorter tests), you can access and print your test results whenever and wherever you like.

Last but not least, Watts designed the TK-DL so it's a snap to use, with no programming required. When you switch the unit on, it automatically checks its calibration and battery power, and documents the results. No guesswork. If you're forgetful about turning it off, it'll even take care of that.

The TK-DL comes in a rugged carrying case with the handgrip and adjustable shoulder strap. The kit includes a set of NiCad batteries, AC battery charger, three six-foot color-coded hoses, a set of brass adapters, and the operatiing maual. Watts stands behind the unit with a full one-year warranty.

The TK-DL also assures that every test is equally accurate. The unit calibrates itself before each test.
