The Tinytag Ultra 2 is the core, general-purpose indoor climate monitoring solution within the basic range. It is designed specifically for environments where there is little to no risk of continuous submersion, making it the standard choice for building management, HVAC testing, indoor environmental research, and office climate monitoring. The Ultra 2 balances cost-effectiveness with professional-grade measurement, focusing primarily on indoor ambient profiles.
Large Memory Capacity: Stores up to 32,000 readings (non-volatile memory ensures data is safe even if the battery runs flat).
Highly Programmable: Supports flexible logging intervals (from 1 second up to 10 days) and dynamic “stop” options (such as stop when full, stop after a set number of readings, or continuous “wrap-around” logging).
Alarms & Triggers: Features 2 fully programmable, latching alarms (via red LED indicators) and supports delayed start times or physical magnetic switch activation.
Practical Form Factor: Housed in a compact, lightweight (55g) ABS case with an IP54 splashproof rating (provided the connector caps are fitted and the unit is hung vertically).
Long Battery Life: Runs on a user-replaceable 3.6V 1/2 AA Lithium battery that typically lasts up to 12 months.
The Tinytag Ultra 2 Temperature series provides lightweight, high-precision indoor telemetry for laboratories, offices, and cold-chain monitoring. Featuring a 32,000-reading non-volatile memory, this IP51-rated fleet includes internal sensor models (TGU-4017), external thermistor probe variants (TGU-4020), specialised dual-channel units (TGU-4510), and high-accuracy PT1000 configurations (TGU-4550), making it the premier choice for flexible, cost-effective environmental tracking.
The Tinytag Ultra 2 TGU-4500 is the definitive, high-precision climate data logger for indoor facilities management, archival storage, and HVAC auditing. Combining a premium internal NTC thermistor and a capacitive relative humidity sensor, this lightweight IP53 splashproof unit logs up to 32,000 readings concurrently, identifying fine ambient air drop-offs down to 0.01°C resolutions at a glance.
