To assure accuracy an individually serial-numbered Traceable certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Unique thru-zero feature allows counting down, alarming, and counting up.
