About This

• Flexible Dual‑Usage：With or Without Probe Detachable external probe supports two working modes. When probe connected, real‑time IN & OUT temperature auto‑alternate on screen and alarm responds to OUT probe reading. Remove probe, auto‑alternate stops; only built‑in IN sensor works and alarm monitors main‑unit ambient temperature. One device for different monitoring needs.
• Customizable High‑Low Audible Temperature Alarm Set your own high and low temperature thresholds. Buzzer beeps 60 seconds per trigger and repeats up to 5 cycles to notify you of abnormal temperature, effectively preventing food spoilage in cold‑storage environments. Factory default alarm: High +28℃, Low ‑28℃.
• Independent IN & OUT Max‑Min Historical Memory Separate max‑min records for IN built‑in sensor and OUT external probe.

Press CLR button to clear stored history and start new monitoring cycle.
