Its design prioritizes user convenience and cleanliness, with an ergonomically designed case that mitigates spills through its sloping shape and a PEEK spill barrier around the stainless steel prism dish.
The centerpiece of this design is the high-definition capacitive touch-screen display, which not only ensures usability in factory settings, even when wearing gloves, but also serves as the focal point for the user-friendly software. Together, the touchscreen and GUI enable swift navigation through user and configuration menus, aided by on-screen graphical prompts for tasks such as method loading, calibration, and routine maintenance.
Standard RFID swipe technology offers operator clearance and maintains a log of functions, especially valuable in FDA-regulated environments adhering to 21 CFR Part 11 or best practices like HACCP.
Measurements with the RFM340T are user-friendly, offering familiar measuring modes or a straightforward Methods system with one-touch configuration for scale, temperature, and data storage. It can store up to 8000 results alongside preset limits for audit purposes, ensuring precise and efficient measurement processes.
