The Cooper-Atkins 6142-20-3 is a high-precision vapor tension thermometer engineered specifically for remote monitoring in cold storage and commercial refrigeration units. This panel mount thermometer features a 2-inch dual-scale dial encased in a durable stainless steel housing, protected by a high-impact polycarbonate lens and bezel. The 48-inch capillary lead allows for versatile placement, enabling technicians to monitor internal air temperatures from the exterior of walk-in freezers or display cases without disrupting the thermal envelope. With a temperature range of -40°F to +60°F (-40°C to +15°C) and an accuracy of ±2°F within the critical 10°F to 40°F range, this industrial refrigerator thermometer is essential for HACCP compliance. The tin-plated bulb and capillary resist corrosion in high-moisture environments, while the NSF certified thermometer design ensures it meets stringent sanitation standards for food safety. Designed for a 3-inch front flange flush mount, it integrates seamlessly into existing equipment panels for a professional, clean installation. Key Benefits Remote Temperature Monitoring: The 48-inch capillary tube provides flexible placement of the sensing bulb to capture accurate data without opening unit doors. Maintenance-Friendly Calibration: Features a recalibrateable dial to maintain high-level accuracy over the life of the instrument. Corrosion Resistance: Tin-plated components and stainless steel housing protect against the oxidative stress typical of commercial kitchens and humid cold rooms. No Power Required: Mechanical vapor tension operation ensures consistent monitoring during power outages. Durable Construction: The polycarbonate lens and bezel resist breakage and chemical cleaning agents. Common Questions Is the Cooper 6142-20-3 suitable for outdoor walk-in units?Yes, the tin-plated bulb and stainless steel casing are designed to handle high humidity and varying exterior conditions common in commercial outdoor installations. What is the best way to install the sensing bulb for accurate readings?For the most precise air temperature data, mount the 5/16-inch bulb in the center of the air stream, away from coil discharge or door openings, and secure the capillary to prevent vibration fatigue. How do I perform a recalibration on this model?This unit is recalibrateable via the adjustment point on the rear; it should be verified against a certified reference thermometer in a stabilized ice bath or thermal block following standard industry protocols.
