Glass thermometers measure precise, network-independent, and cost-effective. Because of their resistance against aggressive media, they are universally usable. Calibrated instruments also serve as test standards for monitoring other instruments. They fulfill national and international standards and norms as well.
We also offer many types of glass thermometers with eco-friendly, mercury-free filling. At your request, our glass thermometers are manufactured with high-grade transparent safety coating (FEP/PTFE). This increases safety – especially in the food sector (HACCP).

ASTM-IP-BS thermometers

We offer you highly precise measuring instruments for standardized material testing. The measurement accuracy lies within the tolerance limits specified by the ASTM, BS, IP and ISO as a matter of course. These precision thermometers are for mineral and fuel testing in particular and granted a network-independent, precise measuring – e.g. for the determination of the flammability point or the viscosity. The stem types have the graduation indestructibly diffused into the glass surface and are acid- and alkali-resistant.
