Large digits permit viewing from across the lab. When counting down, green LED flashes every second for the last ten seconds; red LED flashes when zero is reached and the alarm is sounding. Adjustable alarm volume has three settings: high, low, and off. Timer also counts up showing elapsed time after zero was reached. Traceable® products have an individually-numbered Traceable® certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognised national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable® name, thus saving you both time and money by not having to calibrate separately.
