6. Factory Standard List
Recorder main unit, USB data cable, wall-mounted bracket, anti-theft lock, TL-5903 battery, factory calibration certificate, manual
III. Core Product Advantages
Dual-point 4-channel synchronous monitoring
Can be arranged with 2 independent extension probes, simultaneously monitoring different areas of the warehouse and cold/hot zones in the workshop, one device replacing two single-channel recorders, saving procurement costs.
External Separated Probes The probe is extended through cables and can be inserted into the shelves, equipment cavities, and deep inside the cold storage, without being restricted by the installation location of the main unit. It has good air circulation and responds to temperature and humidity changes much faster than the built-in sensors in the body.
8-year ultra-long battery life
Industrial-grade lithium batteries, which can be installed once and used for many years, significantly reducing the frequency of on-site maintenance.
Ultra-large 2 million data storage capacity
No need to frequently export data, suitable for long-term continuous collection in remote warehouses and unmanned laboratories.
IP65 dustproof and waterproof + anti-theft lock
Can be directly wall-mounted in damp workshops, cold storages, raw material warehouses, and can be used to prevent theft and tampering of records, meeting the official inspection standards of food and supervision, GMP.
Multi-dimensional temperature and humidity calculation
Automatically records dew point and wet bulb values, precisely controls the risks of mold and condensation, suitable for storing cultural relics, electronic components, and wine.
Four. Main application scenarios
1. industry compliance storage (core scenario)
cool storage, vaccine refrigeration storage, biological reagent storage room, hospital pharmacy
Two probes monitor the temperature difference between the upper/lower layers and the entrance/internal of the warehouse throughout the process, trace the temperature and humidity throughout the storage, and are equipped with CFR software to meet GMP and 21CFR regulations for audits
2. Precise raw materials & electronic component warehouses
PCB, sensors, chips, optical components (such as LTH-1550-01) storage, strictly control humidity to prevent oxidation and short circuits; the two probes distinguish the temperature and humidity differences inside and outside the shelves to avoid materials getting damp and being scrapped.
3. Archives, cultural relics, museum exhibition halls
Ancient books, paintings, cultural relic storage rooms, monitor temperature and humidity and dew point, prevent paper cracking and collection mold, provide complete data evidence for cultural tourism supervision inspections.
4. Food, tobacco, wine constant temperature storage
Wine, tea, tobacco, dairy product raw material warehouses, monitor the temperature and humidity at the corners and the center of the warehouse at two points, stabilize the storage environment, avoid product deterioration and loss.
5. Industrial workshops & laboratories
Precision processing workshops, high and low temperature test chambers, quality inspection laboratories, two probes simultaneously collect the temperature and humidity in the production area and the raw material storage area, retain production environment quality inspection records.
6. Building HVAC operation and maintenance
Office building machine rooms, clean workshops, monitor the operation effect of air conditioners, compare the temperature and humidity in different indoor areas, optimize ventilation and energy-saving renovation analysis.
