Each model is engineered to deliver stable, repeatable temperature measurement in hygienic production environments.

Anderson-Negele offers specialized temperature indicators designed to meet stringent industry requirements. The FD digital reference thermometer is ideal for legal pasteurization systems, fully compliant with the Pasteurized Milk Ordinance. It’s also suitable for retort cookers, where its remote-mounted display enhances operator safety by keeping readings away from hazardous areas.

The FH digital temperature gauges provides a modern, battery-operated replacement for traditional mercury-in-glass thermometers on retort cookers. Its digital display simplifies the collection of process data during critical cook cycles, ensuring accuracy and ease of use.

Additionally, our advanced sensors are specifically engineered to monitor and control Clean-In-Place (CIP) chemical concentrations. This optimizes cleaning processes and protects equipment from the damage caused by chemical overuse.

Additional Options for Temperature Measurement

Anderson-Negele’s standard temperature meters provide precise measurements for liquid media, ranging from 0°F to 300°F, with certain models extending from -50°F to 350°F. For easy visual monitoring, these sensors feature an LCD display with digital temperature indication in both °C and °F.

We also offer specialized versions, including battery-powered temperature gauges designed for food and dairy applications, robust gauges tailored for retort processes, and digital reference thermometers ideal for pasteurization and reporting applications. Each option is crafted to meet the specific needs of your process, ensuring reliable and accurate temperature control.
