Description Specifications Literature Description This series of Ashcroft® industrial bimetal thermometers have a hermetic seal and an external adjustment in the rear of the case. As with other Ashcroft® industrial bimetal thermometers, it has a Maxivision® dial which eliminates parallax by placing the pointer on the same plane as the graduations. The connection locations are rear, lower and Every angle™. The hermetic seal prevents entry of moisture into the casing, thus minimizing the possibility of icing or fogging inside the case. The window stays clear, and with the Maxivision® dial, precise readings are certain.Features:Hermetically sealedExternal adjustmentMaxivision® dial±1% full-span accuracy (ASME B 40.3 Grade A)All-welded Stainless Steel constructionSilicone on the coil provides vibration dampening and superior time responseHeavy-duty glass standard; plastic or shatterproof glass optional State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
