VWR Dual Channel Timer Traceable Flashing LED Lot of 2 Timers

Control Company / VWR Traceable Dual-Channel Flashing LED Timer (89140-196 / 5004) – Lot of 2 Timers

The VWR Traceable Dual-Channel Flashing LED Timer (89140-196) is a multi-function digital laboratory timer engineered for precision timekeeping across concurrent analytical assays, incubation protocols, and synthesis reactions. Featuring two independent channels capable of counting down or up from 99 hours, 59 minutes, and 59 seconds with 1-second resolution, this timer provides both high-decibel audible alarms and high-visibility red flashing LED indicators for noisy or darkroom environments. Individually tested and certified to NIST-traceable standards, each unit includes a Traceable Certificate of Calibration ensuring compliance with ISO, FDA, cGMP, and GLP quality management systems. Supplied as a lot of 2 complete timers, this set comes equipped with magnetic backs, flip-out benchtop stands, and wall mounts for versatile laboratory placement.

Technical Performance & Structural Attributes

• Dual Independent Channels: Tracks two separate laboratory operations simultaneously (Channel 1 and Channel 2), with independent display lines and control keys.
• Audible & Visual LED Alarms: Combines an extra-loud 80 dB audible beeper with bright green-to-red flashing LED indicators to signal completion in high-ambient-noise or light-sensitive settings.
• NIST-Traceable Accuracy: Individually calibrated against NIST-traceable standards by an A2LA-accredited ISO/IEC 17025 laboratory to deliver absolute timing precision.
• Integrated Memory Function: Automatically recalls previous alarm time settings for rapid execution of repetitive laboratory incubation cycles.
• Versatile Mounting Architecture: Built-in spring clip, strong rear magnet, flip-open easel stand, and lanyard hole provide multi-surface positioning options.
