The Tinytag Ultra 2 TGU-4500 is a compact, self-contained data logger engineered specifically for precise environmental tracking in indoor and climate-controlled settings. It features an internally mounted 10K NTC thermistor and an integrated capacitive sensor to monitor ambient temperature and relative humidity simultaneously. Designed to secure up to 32,000 readings in non-volatile memory, this device records actual, minimum, and maximum values over customisable intervals. Its specialised electronics provide industry-leading 16-bit measurement resolution, helping facilities protect sensitive assets from microclimatic drift.
Dual Parameter Tracking: Concurrently records both ambient temperature and relative humidity using onboard, factory-calibrated internal sensors.
Massive Non-Volatile Memory: Stores up to 32,000 individual readings (16,000 per channel) safely, preventing data loss even during complete battery depletion.
Flexible Trigger Routines: Offers absolute delayed startup configurations up to 45 days, as well as a magnetic switch trigger option for on-demand field activation.
Advanced Alarm Thresholds: Equipped with two user-programmable, latching LED alarms to provide immediate visual alerts if critical environmental boundaries are breached.
