Key Benefits and Applications

• High-contrast readability — The white opal internal scale with sharp, black markings enhances legibility, reducing reading errors in busy labs and production areas.
• Precision for critical control — Fine graduations, including options as tight as 0.1 °C on selected ranges, support precise monitoring in calibration baths, titrations, and method verification.
• Versatile temperature coverage — Multiple range options span low‑temperature storage, ambient checks, and elevated process temperatures, ideal for chemical, pharmaceutical, food, academic, and R&D environments.
• Durable laboratory construction — Chemical‑resistant glass and a protected internal scale help withstand routine exposure in fume hoods, water or oil baths, and field kits.
• Total immersion confidence — Total‑immersion models deliver accurate readings when the specified column length is submerged, perfect for baths, flasks, and reactors.
• Safety-first options — Organic‑liquid fill options are available to support mercury‑free policies, enhancing safety and environmental stewardship.

Featured technical specifications

• Measurement range options — Available models cover popular laboratory spans such as −100 to +30 °C, −50 to +50 °C, −10 to +150 °C, and −10 to +200 °C, plus narrow analytical windows like +49 to +101 °C for high‑resolution control.
• Graduation and resolution — Clear, metric‑only scales with typical graduations of 1.0 °C or 0.5 °C, and select models offering fine 0.1 °C divisions for greater precision.
• Immersion type — Total‑immersion designs support accurate readings when immersed to the designated depth, minimizing stem‑exposure errors.
• Scale design — Opal (white) internal scale with black print provides outstanding contrast and protects markings from direct chemical contact.
• Indicator liquid — Liquid‑in‑glass performance with organic (spirit) indicator available on many ranges; mercury‑free configurations offered depending on model.
• Overall length — Common overall lengths from 200 mm to 400 mm, selected to suit benchtop use, baths, and in‑process measurements.
• Build quality — Laboratory‑grade, chemically resistant glass body designed for routine use in educational, QC, and industrial settings.
• Calibration readiness — Compatible with laboratory calibration and verification routines; certificates can be requested according to your quality system needs.
