Testo 112 Highly Accurate Temperature Measuring Instrument with PTB Approval
The Testo 112 high-precision thermometer is a specialized single-channel calibration instrument designed for official control measurements by food inspectors, assessors, and quality supervisors. Engineered with a dual technology matrix supporting interchangeable Pt100 and NTC probes, this instrument complies with German legal metrology demands when ordered with the initial conformity assessment. The integrated automatic self-monitoring core validates electronics baseline stability before every measuring cycle, securing absolute data safety in cold storage facilities and high-temperature technical process monitoring profiles.
Industrial & Laboratory Applications
- Official Food Safety Inspection: Certified precision reference device for executing state regulatory audits across distribution hubs and retail networks.
- Deep-Freeze Supply Chain Control: Accurate low-temperature tracking down to -50 °C inside commercial cold storage blocks and transport hubs.
- High-Temperature Processing Quality Auditing: Heat profiling up to +300 °C for processing fryers, oil tanks, and technical cooking blocks.
