The Extech 461830 & 461831 Digital StroboTach gives you two calibration options with the model you choose: standard factory calibration or NIST Calibration Certification. Note that NIST Calibration Certification adds 5 days to this product's lead time.
Completely satisfied with the desk. More impressive was the buying process, knowledge of the sales and support staff, and attention to detail. It's clear that this company is on a mission to help people. They have found a way to differentiate themselves in a crowded market and stand out as a great company which deserves all the success it achieves. We will be adding a second UpLift 900 in the near future. Thank you!
