Monitor and Event Recording Thermometer (Data logging optional)

This professional-grade thermometer series is engineered for high-accuracy and reliable temperature monitoring in refrigerators, freezers, ultra-low temperature freezers, and LN2 storage systems. It is available with or without built-in data logging, making it ideal for cold chain monitoring, laboratory environments, and pharmaceutical storage applications.

Each unit uses a high-grade NTC thermistor or a Class A Pt1000 sensor to ensure precise and consistent temperature measurement. Probe options include a plastic-encapsulated NTC (5 mm diameter × 25 mm length with a 3-meter cable, fully submersible from -50°C to 70°C), a stainless steel NTC probe for ranges up to 125°C, and a stainless steel Pt1000 probe suitable for extreme conditions.

The device features a dual-channel, 3-line LCD display that simultaneously shows current, maximum, and minimum temperatures for two sensor inputs. By pressing the MAX/MIN button, users can view timestamped high/low readings from the past 24 hours (hourly), 7 days (daily), or 30 days (daily).

Internal memory supports up to 318,000 data points, providing secure and traceable temperature records. Audible and visual alarms immediately alert users to any temperature excursions, supporting regulatory compliance and safety standards.

Power is supplied by three AAA batteries or an included DC adapter. The unit offers flexible installation options including handheld use, flat surface placement, stand mounting, or magnetic wall mounting—making it adaptable to various work environments.

Sensor options are available in PTFE or stainless-steel encapsulation, with accuracy levels from ±0.2°C to ±0.1°C to meet different application requirements. Each thermometer is factory-calibrated through a multi-point process and comes with a calibration certificate traceable to SI units via NIST, ensuring measurement reliability and compliance in critical temperature-sensitive applications.
