Buyer Beware: NIST Certification Expiry Date
The online ordering process was seamless and the product itself was delivered promptly. On 5 Oct, 2020, I received the order I placed on 1 October, 2020. Having paid an additional $175.00 for NIST certification, the accompanying certificate had a calibration done date of 9 Jan 2020 and a due date of 9 Jan 2021
Given that I received this unit on 5 Oct., 2020, there is approximately 25% of the calibration validity left, 75% already expired.
I sent a request on October 6th to the customer service e mail for a proportional refund of $131.25 pro rated by 75%, for the payment for NIST certification valid for 1 year. As of Oct 24th there has been no acknowledgement.

Paperless Humidity/Temperature Chart Recorder
I bought the chart recorder for my team to use for about 3 weeks, and the recorder had memory corruption problem. The recorded data can't be exported with the serial connection. I'll soon look into returning the unit.
