This item is identical to our standard DS18B20 but comes with a calibration traceable to the US NIST. Each device comes with an individual calibration certificate provided by Precision Metrology of Wauwatosa, Wisconsin. The certificate is valid for one year, and we will remind you when the calibration is due to expire in plenty of time to arrange re-calibration. This certification makes them suitable for food storage temperature monitoring as required under EU Directive EC No 852/2004.
As these devices have a time limited calibration they will be supplied to order only so that you receive the maximum usage from them. Orders placed before the 14th of the month will be received by you during the first week of the following month. If you wish to buy, please place an order as usual on the web site and we will confirm expected date of delivery.
Note that a minimum order quantity of 50 items applies to this device.
