Ashcroft 100B-1-30-130 Industrial Thermometer

Ashcroft 100B-1-30-130 Industrial Thermometer is a mechanical temperature indicator built for industrial process monitoring. It relies on a bimetal sensing element to translate temperature into a dial reading, delivering a direct, non-electronic measurement suitable for harsh factory environments. The model designation includes a 30–130 range, a specification that appears in Ashcroft’s bimetal thermometer datasheets for similar single‑scale indicators, which are commonly offered in Fahrenheit scales for mid‑range process monitoring. Typical applications include monitoring temperatures in process piping, equipment housings, and storage vessels where a reliable, low‑maintenance thermometer is preferred. Ashcroft, a long‑standing manufacturer of pressure and temperature instrumentation, designs these thermometers to withstand industrial use and provide accurate, steady readings without external power. For technicians selecting instrumentation, this type of thermometer offers passive indication with a robust dial and enclosure, making it suitable for spots where electronic sensors are impractical or undesirable.
