Timers

for Water Quality Testing

---

810005: Features the largest display available on a timer: 3 x 21/2" (76 x 63mm). Can be easily read from across a room. Simultaneously displays either one count up channel and a clock, or two count down channels. All channels have a range of 24 hours with 1 second resolution. Also indicates how much time has elapsed after a countdown alarm sounds and conveniently recalls the last timer setting for reuse.

810046: Although small and easily portable, it features a large display with ¾” high digits. Also unique is an auto-power-off feature to extend battery life (operates only when the timer is idle for 10 minutes and will not interrupt a timing sequence). Counts down from 100 minutes with 1-second resolution. Short warning alarms sound at 3 and 5 minutes prior to the final 30-second alarm. Automatically records elapsed time following the alarm for up to 20 minutes, or until stopped. A memory recalls the last timer setting for repetitive tests. Has a built in stand, pocket clip and magnetic back.
